DESCRIPTION

       Qsub submits batch jobs to the Sun Grid Engine queuing system. Sun Grid
       Engine supports single- and multiple-node jobs. Command can be  a  path
       to  a  binary or a script (see -b below) which contains the commands to
       be run by the job  using  a  shell  (for  example,  sh(1)  or  csh(1)).
       Arguments  to  the  command  are  given  as  command_args to qsub .  If
       command is handled as a script then it is possible to  embed  flags  in
       the  script.  If the first two characters of a script line either match
       ’#$’ or are equal to the prefix  string  defined  with  the  -C  option
       described below, the line is parsed for embedded command flags.

       Qsh  submits  an  interactive  X-windows session to Sun Grid Engine. An
       xterm(1) is brought up from the  executing  machine  with  the  display
       directed  either  to  the X-server indicated by the DISPLAY environment
       variable or as specified with the -display qsh option. Interactive jobs
       are  not  spooled if no resource is available to execute them. They are
       either dispatched to a suitable machine for  execution  immediately  or
       the  user  submitting  the  job  is  notified  by  qsh that appropriate
       resources to execute the job are not available.  xterm_args are  passed
       to  the  xterm(1) executable.  Note, however, that the -e and -ls xterm
       options do not work with qsh .

       Qlogin is similar to qsh in that it submits an interactive job  to  the
       queueing  system. It does not open an xterm(1) window on the X display,
       but uses the current terminal for user I/O. Usually, qlogin establishes
       a telnet(1) connection with the remote host, using standard client- and
       server-side  commands.  These  commands  can  be  configured  with  the
       qlogin_daemon  (server-side,  Sun  Grid  Engine  telnetd  if  not  set,
       otherwise  something  like  /usr/sbin/in.telnetd)  and   qlogin_command
       (client-side,  Sun  Grid  Engine telnet if not set, otherwise something
       like /usr/bin/telnet) parameters in the global and local  configuration
       settings  of  sge_conf(5).   The  client  side command is automatically
       parameterized with the remote host name and port  number  to  which  to
       connect, resulting in an invocation like

              /usr/bin/telnet my_exec_host 2442

       for  example.  Qlogin is invoked exactly like qsh and its jobs can only
       run on INTERACTIVE queues.   Qlogin  jobs  can  only  be  used  if  the
       sge_execd(8) is running under the root account.

       Qrsh  is similar to qlogin in that it submits an interactive job to the
       queuing system.  It uses the current terminal for user  I/O.   Usually,
       qrsh  establishes  a  rsh(1)  connection  with  the  remote host. If no
       command is given to qrsh, an rlogin(1)  session  is  established.   The
       server-side  commands  used  can  be configured with the rsh_daemon and
       rlogin_daemon parameters in the global and local configuration settings
       of  sge_conf(5).   An  Sun  Grid  Engine rshd or rlogind is used if the
       parameters are not set. If the parameters are set, they should  be  set
       to  something  like  /usr/sbin/in.rshd or /usr/sbin/in.rlogind.  On the
       client-side, the rsh_command and rlogin_command parameters can  be  set
       in the global and local configuration settings of sge_conf(5).  If they
       are not set, special Sun Grid  Engine  rsh(1)  and  rlogin(1)  binaries
       delivered with Sun Grid Engine are used.  Use the cluster configuration
       parameters to integrate mechanisms like ssh or the rsh(1) and rlogin(1)
       facilities supplied with the operating system.

       Qrsh  jobs can only run in INTERACTIVE queues unless the option -now no
       is used (see below).  They can also only be run, if the sge_execd(8) is
       running under the root account.

       Qrsh  provides  an  additional  useful  feature  for  integrating  with
       interactive  tools  providing  a  specific  command   shell.   If   the
       environment  variable  QRSH_WRAPPER  is  set  when qrsh is invoked, the
       command interpreter pointed to by QRSH_WRAPPER will be executed to  run
       qrsh  commands  instead of the users login shell or any shell specified
       in the qrsh command-line.  The options -cwd,  -v,   -V,   and  -display
       only apply to batch jobs.

       Qalter  can be used to change the attributes of pending jobs. For array
       jobs with a mix of running and pending tasks (see the -t option below),
       modification  with  qalter  only affects the pending tasks.  Qalter can
       change most of the characteristics of  a  job  (see  the  corresponding
       statements  in  the  OPTIONS section below), including those which were
       defined as embedded flags in the script file (see above).  Some  submit
       options, such as the job script, cannot be changed with I. qalter.

       Qresub  allows the user to create jobs as copies of existing pending or
       running jobs. The copied jobs will have exactly the same attributes  as
       the  ones  from  which  they were copied, except with a new job ID. The
       only modification to the copied jobs supported by qresub is  assignment
       of  a  hold  state with the -h option. This option can be used to first
       copy a job and then change its attributes via qalter.

       Only a manager can use  qresub  on  jobs  submitted  by  another  user.
       Regular users can only use qresub on their own jobs.

       For  qsub,  qsh,  qrsh,  and  qlogin the administrator and the user may
       define default request files (see sge_request(5)) which can contain any
       of the options described below.  If an option in a default request file
       is understood by qsub and qlogin but not by qsh the option is  silently
       ignored if qsh is invoked. Thus you can maintain shared default request
       files for both qsub and qsh.

       A  cluster  wide   default   request   file   may   be   placed   under
       $SGE_ROOT/$SGE_CELL/common/sge_request.   User  private default request
       files  are  processed  under  the  locations   $HOME/.sge_request   and
       $cwd/.sge_request. The working directory local default request file has
       the highest precedence, then the home directory located file  and  then
       the  cluster  global  file.   The option arguments, the embedded script
       flags and the options in the default request files are processed in the
       following order:

              left to right in the script line,
              left to right in the default request files,
              from top to bottom of the script file (qsub only),
              from top to bottom of default request files,
              from left to right of the command line.

       In  other  words, the command line can be used to override the embedded
       flags and the default request settings.  The embedded  flags,  however,
       will override the default settings.

       Note,  that  the  -clear  option  can  be  used to discard any previous
       settings at any time in a default request file, in the embedded  script
       flags,  or in a command-line option. It is, however, not available with
       qalter.

       The options described below can be requested either hard or  soft.   By
       default,  all  requests are considered hard until the -soft option (see
       below) is encountered. The hard/soft status remains in effect until its
       counterpart  is  encountered again.  If all the hard requests for a job
       cannot be met, the job will not be scheduled.  Jobs which cannot be run
       at the present time remain spooled.

OPTIONS

       -@ optionfile
              Forces  qsub,  qrsh, qsh, or qlogin to use the options contained
              in optionfile. The indicated file may contain all valid options.
              Comment lines must start with a "#" sign.

       -a date_time
              Available for qsub and qalter only.

              Defines  or  redefines  the  time  and  date  at  which a job is
              eligible    for     execution.     Date_time     conforms     to
              [[CC]]YY]MMDDhhmm[.SS],  for  the  details, please see Date_time
              in: sge_types(1).

       -ac variable[=value],...
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Adds the given name/value pair(s) to the  job’s  context.  Value
              may  be  omitted.  Sun Grid Engine appends the given argument to
              the list of context variables for the job.  Multiple  -ac,  -dc,
              and -sc options may be given.  The order is important here.

              QALTER  allows changing this option even while the job executes.

       -ar AR_id
              Available for qsub, qalter  qrsh, qsh, or qloginP  only.

              The AR_id AR_is is required.  Assigns the submitted job to be  a
              part  of  an existing Advance Reservation.  The complete list of
              existing  Advance  Reservations  can  be  obtained   using   the
              qrstat(1) command.

       -ar  option adds implicitly the -w e option if not otherwise requested.

       Qalter allows the AR_id of a pending job to be changed.  The AR_id of a
       running job cannot be changed.

       -A account_string
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Identifies  the account to which the resource consumption of the
              job should be charged. The account_string should conform to  the
              name  definition  in  M  sge_types  1  .  In the absence of this
              parameter Sun Grid Engine will place the default account  string
              "sge" in the accounting record of the job.

              Qalter  allows changing this option even while the job executes.

       -b y[es]|n[o]
              Available for qsub, qrsh only. Qalter does  not  allow  changing
              this  option.  This option cannot be embedded in the script file
              itself.

              Gives the user the possibility to  indicate  explicitly  whether
              command  should  be treated as binary or script. If the value of
              -b is ’y’, then command  may be a binary or script.  The command
              might  not  be  accessible  from  the  submission host.  Nothing
              except the path of the command  will  be  transferred  from  the
              submission  host  to  the  execution host. Path aliasing will be
              applied to the path of command before command will be  executed.

              If  the value of -b is ’n’ then command needs to be a script and
              it will be  handled  as  script.  The  script  file  has  to  be
              accessible by the submission host. It will be transferred to the
              execution host. qsub/qrsh will search directive prefixes  within
              script.

              qsub  will  implicitly use -b n whereas qrsh will apply the -b y
              option if nothing else is specified.

       -c occasion_specifier
              Available for qsub and qalter only.

              Defines or redefines whether the job should be checkpointed, and
              if  so,  under  what  circumstances.  The  specification  of the
              checkpointing  occasions  with  this   option   overwrites   the
              definitions   of   the   when  parameter  in  the  checkpointing
              environment (see checkpoint(5)) referenced  by  the  qsub  -ckpt
              switch.  Possible values for occasion_specifier are

              n           no checkpoint is performed.
              s           checkpoint when batch server is shut down.
              m           checkpoint at minimum CPU interval.
              x           checkpoint when job gets suspended.
              <interval>  checkpoint in the specified time interval.

              The  minimum  CPU interval is defined in the queue configuration
              (see queue_conf(5) for details).  <interval> has to be specified
              in  the  format  hh:mm:ss.   The  maximum  of <interval> and the
              queue’s minimum CPU interval is used if <interval> is specified.
              This  is  done  to  ensure  that  a machine is not overloaded by
              checkpoints being generated too frequently.

       -ckpt ckpt_name
              Available for qsub and qalter only.

              Selects the checkpointing environment (see checkpoint(5)) to  be
              used  for  checkpointing  the job. Also declares the job to be a
              checkpointing job.

       -clear Available for qsub, qsh, qrsh, and qlogin only.

              Causes all elements of the  job  to  be  reset  to  the  initial
              default  status  prior  to  applying  any modifications (if any)
              appearing in this specific command.

       -cwd   Available for qsub, qsh, qrsh and qalter only.

              Execute the job from the current working directory.  This switch
              will  activate  Sun Grid Engine’s path aliasing facility, if the
              corresponding   configuration    files    are    present    (see
              sge_aliases(5)).

              In  the  case  of qalter, the previous definition of the current
              working directory will be overwritten if qalter is executed from
              a different directory than the preceding qsub or qalter.

              Qalter  allows changing this option even while the job executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -C prefix_string
              Available for qsub and qrsh with script submission (-b n).

              Prefix_string  defines  the  prefix that declares a directive in
              the job’s command. The  prefix  is  not  a  job  attribute,  but
              affects  the  behavior  of  qsub  and  qrsh. If prefix is a null
              string, the command will not be scanned for embedded directives.
              The  directive  prefix  consists  of two ASCII characters which,
              when appearing in the first two bytes of a script line, indicate
              that what follows is an Sun Grid Engine command.  The default is
              "#$".
              The user should be aware  that  changing  the  first  delimiting
              character  can  produce  unforeseen  side effects. If the script
              file contains anything other than a "#" character in  the  first
              byte  position of the line, the shell processor for the job will
              reject the line and may exit the job prematurely.
              If the -C option is present in the script file, it is ignored.

       -dc variable,...
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Removes the given variable(s) from the job’s context.   Multiple
              -ac, -dc, and -sc options may be given.  The order is important.

              Qalter allows changing this option even while the job  executes.

       -display display_specifier
              Available for qsh only.

              Directs  xterm(1)  to  use display_specifier in order to contact
              the X server.  The display_specifier has to contain the hostname
              part  of  the display name (e.g. myhost:1).  Local display names
              (e.g. :0) cannot be used in grid environments.  Values set  with
              the  -display  option  overwrite  settings  from  the submission
              environment and from -v command line options.

       -dl date_time
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Specifies the deadline initiation time in  [[CC]YY]MMDDhhmm[.SS]
              format  (see  -a  option above). The deadline initiation time is
              the time at which a deadline job has to reach top priority to be
              able  to  complete  within a given deadline. Before the deadline
              initiation time the priority of a deadline job  will  be  raised
              steadily  until  it reaches the maximum as configured by the Sun
              Grid Engine administrator.
              This option is applicable  only  for  users  allowed  to  submit
              deadline jobs.

       -e [[hostname]:]path,...
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Defines or redefines the path used for the standard error stream
              of the job. For qsh, qrsh and qlogin  only  the  standard  error
              stream  of  prolog  and  epilog  is  redirected.   If  the  path
              constitutes an absolute path name, the error-path  attribute  of
              the job is set to path, including the hostname. If the path name
              is relative, Sun  Grid  Engine  expands  path  either  with  the
              current  working  directory path (if the -cwd switch (see above)
              is also specified) or with the home directory path. If  hostname
              is  present,  the  standard  error  stream will be placed in the
              corresponding location only if the job  runs  on  the  specified
              host.  If  the path contains a ":" without a hostname, a leading
              ":" has to be specified.

              By default the file name for interactive jobs is /dev/null.  For
              batch  jobs  the default file name has the form job_name.ejob_id
              and job_name.ejob_id.task_id for array job tasks (see -t  option
              below).

              If  path  is  a  directory, the standard error stream of the job
              will be put in this directory under the default file  name.   If
              the  pathname  contains  certain  pseudo  environment variables,
              their value will be expanded at runtime of the job and  will  be
              used  to  constitute  the  standard  error stream path name. The
              following pseudo environment variables are supported currently:

              $HOME       home directory on execution machine
              $USER       user ID of job owner
              $JOB_ID     current job ID
              $JOB_NAME   current job name (see -N option)
              $HOSTNAME   name of the execution host
              $TASK_ID    array job task index number

              Alternatively to $HOME the tilde sign "~" can be used as  common
              in  csh(1)  or  ksh(1).   Note,  that the "~" sign also works in
              combination with user names, so that "~<user>"  expands  to  the
              home directory of <user>. Using another user ID than that of the
              job owner requires corresponding permissions, of course.

              Qalter allows changing this option even while the job  executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -hard  Available for qsub, qsh, qrsh, qlogin and qalter only.

              Signifies  that  all  resource  requirements  following  in  the
              command  line will be hard requirements and must be satisfied in
              full before a job can be scheduled.
              As Sun Grid Engine scans the command line and  script  file  for
              Sun  Grid  Engine  options  and  parameters  it builds a list of
              resources required by a job.  All  such  resource  requests  are
              considered  as  absolutely essential for the job to commence. If
              the -soft option (see below) is encountered during the scan then
              all  following  resources  are designated as "soft requirements"
              for execution, or "nice-to-have,  but  not  essential".  If  the
              -hard  flag  is  encountered  at  a later stage of the scan, all
              resource requests following it once  again  become  "essential".
              The  -hard  and  -soft options in effect act as "toggles" during
              the scan.

       -h | -h {u|s|o|n|U|O|S}...
              Available for qsub, qrsh (with  command  argument),  qalter  and
              qresub.

              List  of holds to place on a job, a task or some tasks of a job.

              ‘u’  denotes a user hold.
              ‘s’  denotes a system hold.
              ‘o’  denotes a operator hold.
              ‘n’  denotes no hold.

              As long as any hold other than ‘n’ is assigned to  the  job  the
              job  is  not  eligible  for execution. Holds can be released via
              qalter and qrls(1).  In case of qalter this is supported by  the
              following additional option specifiers for the -h switch:

              ‘U’  removes a user hold.
              ‘S’  removes a system hold.
              ‘O’  removes a operator hold.

              Sun  Grid  Engine managers can assign and remove all hold types,
              Sun Grid  Engine  operators  can  assign  and  remove  user  and
              operator  holds, and users can only assign or remove user holds.

              In the case of qsub only user holds can be placed on a  job  and
              thus  only the first form of the option with the -h switch alone
              is allowed.  As opposed to this, qalter requires the second form
              described above.

              An  alternate  means  to assign hold is provided by the qhold(1)
              facility.

              If the job is a array job (see the -t option below),  all  tasks
              specified   via   -t   are   affected   by   the   -h  operation
              simultaneously.

              Qalter allows changing this option even while the job  executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -help  Prints  a listing of all options.

       -hold_jid wc_job_list
              Available for qsub, qrsh, and  qalter  only.  See  sge_types(1).
              for wc_job_list definition.

              Defines  or  redefines  the job dependency list of the submitted
              job. A reference by job name or pattern is only accepted if  the
              referenced  job  is owned by the same user as the referring job.
              The submitted job is not eligible for execution unless all  jobs
              referenced  in  the  comma-separated job id and/or job name list
              have completed.  If any of the referenced jobs exits  with  exit
              code   100,   the  submitted  job  will  remain  ineligible  for
              execution.

              With the help of job names or regular pattern one can specify  a
              job  dependency  on multiple jobs satisfying the regular pattern
              or on all jobs with the requested name.  The  name  dependencies
              are  resolved at submit time and can only be changed via qalter.
              New jobs or name changes of other jobs will not  be  taken  into
              account.

              Qalter  allows changing this option even while the job executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -hold_jid_ad wc_job_list
              Available  for  qsub,  qrsh,  and qalter only. See sge_types(1).
              for wc_job_list definition.

              Defines or redefines  the  job  array  dependency  list  of  the
              submitted  job.  A  reference  by  job  name  or pattern is only
              accepted if the referenced job is owned by the same user as  the
              referring  job.  Each  sub-task  of  the  submitted  job  is not
              eligible for execution unless the corresponding sub-tasks of all
              jobs  referenced  in  the comma-separated job id and/or job name
              list have completed.  If any array task of the  referenced  jobs
              exits  with  exit code 100, the dependent tasks of the submitted
              job will remain ineligible for execution.

              With the help of job names or regular pattern one can specify  a
              job  dependency  on multiple jobs satisfying the regular pattern
              or on all jobs with the requested name.  The  name  dependencies
              are  resolved at submit time and can only be changed via qalter.
              New jobs or name changes of other jobs will not  be  taken  into
              account.

              If  either  the  submitted job or any job in wc_job_list are not
              array jobs with the same  range  of  sub-tasks  (see  -t  option
              below),  the request list will be rejected and the job create or
              modify operation will error.

              qalter allows changing this option even while the job  executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -i [[hostname]:]file,...
              Available for qsub, and qalter only.

              Defines or redefines the file used for the standard input stream
              of  the  job.  If the file constitutes an absolute filename, the
              input-path attribute of the job is set to  path,  including  the
              hostname.  If the path name is relative, Sun Grid Engine expands
              path either with the current working directory path (if the -cwd
              switch (see above) is also specified) or with the home directory
              path. If hostname is present, the standard input stream will  be
              placed in the corresponding location only if the job runs on the
              specified host. If the path contains a ":" without a hostname, a
              leading ":" has to be specified.

              By default /dev/null is the input stream for the job.

              It  is  possible  to  use certain pseudo variables, whose values
              will be expanded at runtime of the  job  and  will  be  used  to
              express  the standard input stream as described in the -e option
              for the standard error stream.

              Qalter allows changing this option even while the job  executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -inherit
              Available only for qrsh and qmake(1).

              qrsh allows the user to start a task  in  an  already  scheduled
              parallel  job.   The option -inherit tells qrsh to read a job id
              from the environment variable JOB_ID  and  start  the  specified
              command  as  a  task in this job. Please note that in this case,
              the hostname of the host where the command will be executed must
              precede the command to execute; the syntax changes to

              qrsh  -inherit [ other options ] hostname command [ command_args
              ]

              Note also, that in combination with -inherit, most other command
              line options will be ignored.  Only the options -verbose, -v and
              -V will be interpreted.  As a replacement to option -cwd  please
              use -v PWD.

              Usually  a  task should have the same environment (including the
              current  working  directory)  as  the  corresponding   job,   so
              specifying   the   option   -V   should  be  suitable  for  most
              applications.

              Note: If in your system the qmaster tcp port is  not  configured
              as   a   service,   but  rather  via  the  environment  variable
              SGE_QMASTER_PORT, make sure that this variable  is  set  in  the
              environment when calling qrsh or qmake with the -inherit option.
              If you call qrsh or qmake with the -inherit option from within a
              job   script,   export  SGE_QMASTER_PORT  with  the  option  "-v
              SGE_QMASTER_PORT" either as a command argument  or  an  embedded
              directive.

       -j y[es]|n[o]
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Specifies whether or not the standard error stream of the job is
              merged into the standard output stream.
              If both the -j y and the -e options are present, Sun Grid Engine
              sets but ignores the error-path attribute.

              Qalter  allows changing this option even while the job executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -js job_share
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Defines  or redefines the job share of the job relative to other
              jobs.  Job share is an unsigned integer value.  The default  job
              share value for jobs is 0.

              The   job  share  influences  the  Share  Tree  Policy  and  the
              Functional Policy. It has no effect on the Urgency and  Override
              Policies  (see  share_tree(5),  sched_conf(5)  and  the Sun Grid
              Engine  Installation  and  Administration  Guide   for   further
              information on the resource management policies supported by Sun
              Grid Engine).

              In case of the Share  Tree  Policy,  users  can  distribute  the
              tickets  to  which  they are currently entitled among their jobs
              using different shares assigned via -js. If all  jobs  have  the
              same  job  share  value,  the  tickets  are  distributed evenly.
              Otherwise, jobs receive tickets relative to  the  different  job
              shares.  Job  shares are treated like an additional level in the
              share tree in the latter case.

              In connection with the Functional Policy, the job share  can  be
              used to weight jobs within the functional job category.  Tickets
              are distributed relative to any uneven  job  share  distribution
              treated  as  a  virtual  share distribution level underneath the
              functional job category.

              If both the Share Tree and the Functional Policy are active, the
              job shares will have an effect in both policies, and the tickets
              independently derived in each of them are  added  to  the  total
              number of tickets for each job.

       -l resource=value,...
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Launch  the  job  in  a  Sun Grid Engine queue meeting the given
              resource  request  list.   In  case  of  qalter   the   previous
              definition is replaced by the specified one.
              complex(5) describes how a list of available resources and their
              associated valid value specifiers can be obtained.
              There may be multiple -l switches in a single command.  You  may
              request  multiple -l options to be soft or hard both in the same
              command line. In case of  a  serial  job  multiple  -l  switches
              refine the definition for the sought queue.

              Qalter  allows  changing the value of this option even while the
              job is running, but only if the initial list of  resources  does
              not contain a resource that is marked as consumable. However the
              modification will only be effective after a restart or migration
              of the job.

       -m b|e|a|s|n,...
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Defines  or  redefines  under  which circumstances mail is to be
              sent to the job owner or to the users defined with the -M option
              described   below.  The  option  arguments  have  the  following
              meaning:

              ‘b’     Mail is sent at the beginning of the job.
              ‘e’     Mail is sent at the end of the job.
              ‘a’     Mail is sent when the job is aborted or
                      rescheduled.
              ‘s’     Mail is sent when the job is suspended.
              ‘n’     No mail is sent.

              Currently no mail is sent when a job is suspended.

              Qalter allows changing the b, e, and  a  option  arguments  even
              while  the  job  executes.  The  modification  of  the  b option
              argument will only be in effect after a restart or migration  of
              the job, however.

       -M user[@host],...
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Defines  or redefines the list of users to which the server that
              executes the job has to send mail,  if  the  server  sends  mail
              about  the  job.   Default  is  the job owner at the originating
              host.

              Qalter allows changing this option even while the job  executes.

       -masterq wc_queue_list
              Available   for  qsub,  qrsh,  qsh,  qlogin  and  qalter.   Only
              meaningful for parallel jobs, i.e. together with the -pe option.

              Defines or redefines a list of cluster queues, queue domains and
              queue instances which may be used to become the so called master
              queue  of  this  parallel  job.  A  more detailed description of
              wc_queue_list can be found in sge_types(1).  The master queue is
              defined  as  the  queue  where  the parallel job is started. The
              other queues to which the parallel job spawns tasks  are  called
              slave queues.  A parallel job only has one master queue.

              This  parameter has all the properties of a resource request and
              will be merged with requirements  derived  from  the  -l  option
              described above.

              Qalter  allows changing this option even while the job executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -notify
              Available for qsub, qrsh (with command) and qalter only.

              This  flag,  when  set  causes Sun Grid Engine to send "warning"
              signals  to  a  running  job  prior  to  sending   the   signals
              themselves.  If  a  SIGSTOP  is  pending, the job will receive a
              SIGUSR1 several seconds before the  SIGSTOP.  If  a  SIGKILL  is
              pending,  the  job will receive a SIGUSR2 several seconds before
              the SIGKILL.  The amount of time  delay  is  controlled  by  the
              notify    parameter    in    each   queue   configuration   (see
              queue_conf(5)).

              Note that the Linux operating system "misused" the user  signals
              SIGUSR1  and SIGUSR2 in some early Posix thread implementations.
              You might not want to use the -notify option if you are  running
              multi-threaded   applications   in   your   jobs   under  Linux,
              particularly on 2.0 or earlier kernels.

              Qalter allows changing this option even while the job  executes.

       -now y[es]|n[o]
              Available for qsub, qsh, qlogin and qrsh.

              -now  y  tries  to  start the job immediately or not at all. The
              command returns 0 on success, or 1 on failure (also if  the  job
              could  not  be scheduled immediately).  For array jobs submitted
              with the  -now  option,  if  all  tasks  cannot  be  immediately
              scheduled,  no  tasks are scheduled.  -now y is default for qsh,
              qlogin and qrsh
              With the -now n option, the job will be  put  into  the  pending
              queue  if  it  cannot be executed immediately. -now n is default
              for qsub.

       -N name
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              The  name  of  the  job.  The  name  should  follow  the  "name"
              definition in sge_types(1).  Invalid job names will be denied at
              submit time.
              If the -N option is not present, Sun  Grid  Engine  assigns  the
              name  of  the job script to the job after any directory pathname
              has been removed from the script-name. If  the  script  is  read
              from standard input, the job name defaults to STDIN.
              In  the  case of qsh or qlogin with the -N option is absent, the
              string ‘INTERACT’ is assigned to the job.
              In the case of qrsh if the -N option is  absent,  the  resulting
              job  name  is determined from the qrsh command line by using the
              argument string up to the first occurrence  of  a  semicolon  or
              whitespace and removing the directory pathname.

              Qalter  allows changing this option even while the job executes.

       -noshell
              Available only for qrsh with a command line.

              Do not start the command line given to qrsh in  a  user’s  login
              shell, i.e.  execute it without the wrapping shell.

              This  option can be used to speed up execution as some overhead,
              like the shell startup and sourcing the shell resource files, is
              avoided.

              This  option  can only be used if no shell-specific command line
              parsing is required. If the command line contains  shell  syntax
              like  environment  variable  substitution  or  (back) quoting, a
              shell must be started.  In this case,  either  do  not  use  the
              -noshell option or include the shell call in the command line.

              Example:
              qrsh echo ’$HOSTNAME’
              Alternative call with the -noshell option
              qrsh -noshell /bin/tcsh -f -c ’echo $HOSTNAME’

       -nostdin
              Available only for qrsh.

              Suppress  the  input stream STDIN - qrsh will pass the option -n
              to the rsh(1) command. This is especially  useful,  if  multiple
              tasks  are  executed  in  parallel using qrsh, e.g. in a make(1)
              process - it would be undefined, which  process  would  get  the
              input.

       -o [[hostname]:]path,...
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              The  path  used  for  the standard output stream of the job. The
              path is handled as described in the -e option for  the  standard
              error stream.

              By  default  the  file  name  for  standard  output has the form
              job_name.ojob_id  and  job_name.ojob_id.task_id  for  array  job
              tasks (see -t option below).

              Qalter  allows changing this option even while the job executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -ot override_tickets
              Available for qalter only.

              Changes  the  number  of override tickets for the specified job.
              Requires manager/operator privileges.

       -P project_name
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Specifies the  project  to  which  this  job  is  assigned.  The
              administrator  needs  to  give permission to individual users to
              submit  jobs  to  a  specific  project.  (see  -aprj  option  to
              qconf(1)).

       -p priority
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Defines  or  redefines the priority of the job relative to other
              jobs.  Priority is an integer in the range -1023 to  1024.   The
              default priority value for jobs is 0.

              Users  may  only  decrease the priority of their jobs.  Sun Grid
              Engine  managers  and  administrators  may  also  increase   the
              priority  associated  with  jobs.  If  a  pending job has higher
              priority, it is earlier eligible for being dispatched by the Sun
              Grid Engine scheduler.

       -pe parallel_environment n[-[m]]|[-]m,...
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Parallel  programming  environment (PE) to instantiate. For more
              detail about PEs, please see the sge_types(1).

              Qalter allows changing this option even while the job  executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -pty y[es]|n[o]
              Available for qrsh and qlogin only.

              -pty yes enforces the job to be started  in  a  pseudo  terminal
              (pty).  If  no  pty  is available, the job start fails.  -pty no
              enforces the job to be started without a pty.  By default,  qrsh
              without a command and qlogin start the job in a pty, qrsh with a
              command starts the job without a pty.

       -q wc_queue_list
              Available for qsub, qrsh, qsh, qlogin and qalter.

              Defines or redefines a list of cluster queues, queue domains  or
              queue  instances  which  may be used to execute this job. Please
              find a  description  of  wc_queue_list  in  sge_types(1).   This
              parameter  has all the properties of a resource request and will
              be merged with requirements derived from the -l option described
              above.

              Qalter  allows changing this option even while the job executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -R y[es]|n[o]
              Available for qsub, qrsh, qsh, qlogin and qalter.

              Indicates  whether  a  reservation  for this job should be done.
              Reservation  is  never  done  for  immediate  jobs,  i.e.   jobs
              submitted   using   the  -now  yes  option.   Please  note  that
              regardless of the reservation request, job reservation might  be
              disabled  using  max_reservation  in  sched_conf(5) and might be
              limited only to a certain number of high priority jobs.

              By default jobs are submitted with the -R n option.

       -r y[es]|n[o]
              Available for qsub and qalter only.

              Identifies the ability of a job to be  rerun  or  not.   If  the
              value  of  -r  is  ’yes’,  the  job will be rerun if the job was
              aborted without leaving  a  consistent  exit  state.   (This  is
              typically  the  case  if  the  node  on which the job is running
              crashes).  If -r is ’no’, the job will not be  rerun  under  any
              circumstances.
              Interactive  jobs  submitted  with  qsh,  qrsh or qlogin are not
              rerunnable.

              Qalter allows changing this option even while the job  executes.

       -sc variable[=value],...
              Available for qsub, qsh, qrsh, qlogin and qalter only.

              Sets  the given name/value pairs as the job’s context. Value may
              be omitted.  Sun  Grid  Engine  replaces  the  job’s  previously
              defined  context  with  the one given as the argument.  Multiple
              -ac, -dc, and -sc options may be given.  The order is important.
              Contexts  provide  a  way to dynamically attach and remove meta-
              information to and from a job. The  context  variables  are  not
              passed to the job’s execution context in its environment.

              Qalter  allows changing this option even while the job executes.

       -shell y[es]|n[o]
              Available only for qsub.

              -shell n causes qsub to execute the command line directly, as if
              by  exec(2).   No  command  shell  will be executed for the job.
              This option only applies when -b y is also used.  Without -b  y,
              -shell n has no effect.

              This  option can be used to speed up execution as some overhead,
              like the shell startup and sourcing the shell resource files  is
              avoided.

              This  option  can only be used if no shell-specific command line
              parsing is required. If the command line contains shell  syntax,
              like  environment  variable  substitution  or  (back) quoting, a
              shell must be started.  In this  case  either  do  not  use  the
              -shell  n  option  or  execute the shell as the command line and
              pass the path to the executable as a parameter.

              If a job executed with the -shell n option fails due to  a  user
              error,  such  as an invalid path to the executable, the job will
              enter the error state.

              -shell y cancels the effect of a previous -shell n.   Otherwise,
              it has no effect.

              See -b and -noshell for more information.

       -soft  Available for qsub, qsh, qrsh, qlogin and qalter only.

              Signifies  that  all  resource  requirements  following  in  the
              command line will be soft requirements and are to be  filled  on
              an "as available" basis.
              As  Sun  Grid  Engine scans the command line and script file for
              Sun Grid Engine options and parameters,  it  builds  a  list  of
              resources  required  by  the job. All such resource requests are
              considered as absolutely essential for the job to  commence.  If
              the  -soft  option  is  encountered  during  the  scan  then all
              following resources are designated as  "soft  requirements"  for
              execution,  or  "nice-to-have,  but not essential". If the -hard
              flag (see above) is encountered at a later stage  of  the  scan,
              all   resource   requests   following   it   once  again  become
              "essential". The -hard  and  -soft  options  in  effect  act  as
              "toggles" during the scan.

       -sync y[es]|n[o]
              Available for qsub.

              -sync  y  causes  qsub  to  wait  for the job to complete before
              exiting.  If the job completes successfully,  qsubs  exit  code
              will be that of the completed job.  If the job fails to complete
              successfully, qsub will print out a error message indicating why
              the  job  failed  and  will  have an exit code of 1.  If qsub is
              interrupted, e.g. with CTRL-C, before the job completes, the job
              will be canceled.
              With  the  -sync n option, qsub will exit with an exit code of 0
              as soon as the  job  is  submitted  successfully.   -sync  n  is
              default for qsub.
              If  -sync y is used in conjunction with -now y, qsub will behave
              as though only  -now  y  were  given  until  the  job  has  been
              successfully  scheduled,  after  which  time qsub will behave as
              though only -sync y were given.
              If -sync y is used in conjunction with -t n[-m[:i]],  qsub  will
              wait for all the job’s tasks to complete before exiting.  If all
              the job’s tasks complete successfully, qsubs exit code will  be
              that of the first completed job tasks with a non-zero exit code,
              or 0 if all job tasks exited with an exit code of 0.  If any  of
              the  job’s  tasks fail to complete successfully, qsub will print
              out an error message indicating why the job task(s)  failed  and
              will  have an exit code of 1.  If qsub is interrupted, e.g. with
              CTRL-C, before the job completes, all of the job’s tasks will be
              canceled.

       -S [[hostname]:]pathname,...
              Available for qsub, qsh and qalter.

              Specifies  the interpreting shell for the job. Only one pathname
              component without a host specifier is valid and  only  one  path
              name  for  a  given  host  is  allowed.  Shell  paths  with host
              assignments define the interpreting shell for  the  job  if  the
              host  is  the  execution  host.  The  shell  path  without  host
              specification is used if the execution host matches none of  the
              hosts in the list.

              Furthermore,   the  pathname  can  be  constructed  with  pseudo
              environment variables as described for the -e option above.

              In the case of qsh the specified shell path is used  to  execute
              the  corresponding  command interpreter in the xterm(1) (via its
              -e option) started on behalf of the interactive job.

              Qalter allows changing this option even while the job  executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -t n[-m[:s]]
              Available for qsub and qalter only.

              Submits a so called Array Job, i.e. an array of identical  tasks
              being  differentiated  only by an index number and being treated
              by Sun Grid Engine almost like a  series  of  jobs.  The  option
              argument  to  -t specifies the number of array job tasks and the
              index number which will be associated with the tasks. The  index
              numbers  will  be  exported to the job tasks via the environment
              variable SGE_TASK_ID. The option arguments n, m and  s  will  be
              available  through  the  environment  variables  SGE_TASK_FIRST,
              SGE_TASK_LAST and  SGE_TASK_STEPSIZE.

              Following restrictions apply to the values n and m:

                     1 <= n <= MIN(2^31-1, max_aj_tasks)
                     1 <= m <= MIN(2^31-1, max_aj_tasks)
                     n <= m

              max_aj_tasks  is  defined  in  the  cluster  configuration  (see
              sge_conf(5))

              The  task  id  range  specified  in the option argument may be a
              single number, a simple range of the form n-m or a range with  a
              step  size.  Hence,  the task id range specified by 2-10:2 would
              result in the task id indexes 2, 4, 6, 8, and 10, for a total of
              5   identical   tasks,   each   with  the  environment  variable
              SGE_TASK_ID containing one of the 5 index numbers.

              All array job tasks  inherit  the  same  resource  requests  and
              attribute definitions as specified in the qsub or qalter command
              line,  except  for  the  -t  option.  The  tasks  are  scheduled
              independently    and,    provided    enough   resources   exist,
              concurrently, very much like separate jobs.  However,  an  array
              job  or a sub-array there of can be accessed as a single unit by
              commands like qmod(1) or qdel(1).  See the corresponding  manual
              pages for further detail.

              Array  jobs  are  commonly  used  to  execute  the  same type of
              operation on varying input data sets correlated  with  the  task
              index number. The number of tasks in a array job is unlimited.

              STDOUT  and  STDERR  of  array  job  tasks  will be written into
              different files with the default location

              <jobname>.[’e’|’o’]<job_id>’.’<task_id>

              In order to change this default, the  -e  and  -o  options  (see
              above)   can  be  used  together  with  the  pseudo  environment
              variables  $HOME,  $USER,  $JOB_ID,  $JOB_NAME,  $HOSTNAME,  and
              $SGE_TASK_ID.

              Note,  that  you  can  use  the output redirection to divert the
              output of all tasks into the same file, but the result  of  this
              is undefined.

       -terse Available for qsub only.

              -terse  causes  the  qsub  to display only the job-id of the job
              being submitted rather than the regular "Your job  ..."  string.
              In case of an error the error is reported on stderr as usual.
              This  can be helpful for scripts which need to parse qsub output
              to get the job-id.

       -u username,...
              Available for qalter only. Changes are only made on  those  jobs
              which   were  submitted  by  users  specified  in  the  list  of
              usernames.  For managers it is possible to use the qalter -u*’
              command to modify all jobs of all users.

              If  you  use  the  -u  switch  it is not permitted to specify an
              additional wc_job_range_list.

       -v variable[=value],...
              Available for qsub, qrsh (with command argument) and qalter.

              Defines or redefines the environment variables to be exported to
              the  execution  context of the job.  If the -v option is present
              Sun Grid Engine will add the environment  variables  defined  as
              arguments  to  the  switch  and, optionally, values of specified
              variables, to the execution context of the job.

              Qalter allows changing this option even while the job  executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       -verbose
              Available only for qrsh and qmake(1).

              Unlike qsh and qlogin, qrsh does not  output  any  informational
              messages  while  establishing  the  session,  compliant with the
              standard rsh(1) and  rlogin(1)  system  calls.   If  the  option
              -verbose  is set, qrsh behaves like the qsh and qlogin commands,
              printing information  about  the  process  of  establishing  the
              rsh(1) or rlogin(1) session.

       -verify
              Available for qsub, qsh, qrsh, qlogin and qalter.

              Instead  of  submitting a job, prints detailed information about
              the would-be job as though qstat(1) -j were used, including  the
              effects of command-line parameters and the external environment.

       -V     Available for qsub, qsh, qrsh with command, qalter and qresub.

              Specifies that all environment variables active within the  qsub
              utility be exported to the context of the job.

       -w e|w|n|v
              Available for qsub, qsh, qrsh, qlogin and qalter.

              Specifies  a validation level applied to the job to be submitted
              (qsub, qlogin, and qsh) or the specified  queued  job  (qalter).
              The information displayed indicates whether the job can possibly
              be scheduled assuming  an  empty  system  with  no  other  jobs.
              Resource requests exceeding the configured maximal thresholds or
              requesting unavailable resource attributes are  possible  causes
              for jobs to fail this validation.

              The  specifiers  e,  w,  n and v define the following validation
              modes:

              ‘e’  error - jobs with invalid requests will be
                   rejected; the default for qrsh, qsh
                   and qlogin.
              ‘w’  warning - only a warning will be displayed
                   for invalid requests.
              ‘n’  none - switches off validation; the default for
                   qsub and qalter.
              ‘v’  verify - does not submit the job but prints a
                   validation report.

              Note, that the necessary checks are  performance  consuming  and
              hence the checking is switched off by default.

       -wd working_dir
              Available for qsub, qsh, qrsh and qalter only.

              Execute  the  job  from  the directory specified in working_dir.
              This switch  will  activate  Sun  Grid  Engine’s  path  aliasing
              facility,  if  the corresponding configuration files are present
              (see sge_aliases(5)).

              Qalter allows changing this option even while the job  executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       command
              Available for qsub and qrsh only.

              The job’s scriptfile or  binary.   If  not  present  or  if  the
              operand  is  the  single-character  string  ’-’,  qsub reads the
              script from standard input.

       command_args
              Available for qsub, qrsh and qalter only.

              Arguments to the job. Not valid if the script  is  entered  from
              standard input.

              Qalter  allows changing this option even while the job executes.
              The modified parameter will only be in effect after a restart or
              migration of the job, however.

       xterm_args
              Available for qsh only.

              Arguments   to  the  xterm(1)  executable,  as  defined  in  the
              configuration.  For details, refer to sge_conf(5)).

ENVIRONMENTAL VARIABLES

       SGE_ROOT       Specifies the location of the Sun Grid  Engine  standard
                      configuration files.

       SGE_CELL       If  set,  specifies the default Sun Grid Engine cell. To
                      address a Sun Grid Engine  cell  qsub,  qsh,  qlogin  or
                      qalter use (in the order of precedence):

                             The name of the cell specified in the environment
                             variable SGE_CELL, if it is set.

                             The name of the default cell, i.e. default.

       SGE_DEBUG_LEVEL
                      If set,  specifies  that  debug  information  should  be
                      written  to  stderr.  In addition the level of detail in
                      which debug information is generated is defined.

       SGE_QMASTER_PORT
                      If set, specifies the tcp port on  which  sge_qmaster(8)
                      is  expected to listen for communication requests.  Most
                      installations will use a  services  map  entry  for  the
                      service "sge_qmaster" instead to define that port.

       DISPLAY        For  qsh  jobs  the  DISPLAY  has to be specified at job
                      submission.  If the DISPLAY is  not  set  by  using  the
                      -display  or  the -v switch, the contents of the DISPLAY
                      environment variable are used as default.

       In addition to those environment variables specified to be exported  to
       the  job  via the -v or the -V option (see above) qsub, qsh, and qlogin
       add the following variables with the indicated values to  the  variable
       list:

       SGE_O_HOME     the home directory of the submitting client.

       SGE_O_HOST     the  name  of the host on which the submitting client is
                      running.

       SGE_O_LOGNAME  the LOGNAME of the submitting client.

       SGE_O_MAIL     the MAIL of the submitting  client.  This  is  the  mail
                      directory of the submitting client.

       SGE_O_PATH     the executable search path of the submitting client.

       SGE_O_SHELL    the SHELL of the submitting client.

       SGE_O_TZ       the time zone of the submitting client.

       SGE_O_WORKDIR  the  absolute  path  of the current working directory of
                      the submitting client.

       Furthermore, Sun Grid Engine sets additional variables into  the  job’s
       environment, as listed below.

       ARC

       SGE_ARCH       The  Sun  Grid  Engine  architecture name of the node on
                      which the job is running. The name is  compiled-in  into
                      the sge_execd(8) binary.

       SGE_CKPT_ENV   Specifies  the  checkpointing  environment  (as selected
                      with the -ckpt option) under which a  checkpointing  job
                      executes. Only set for checkpointing jobs.

       SGE_CKPT_DIR   Only  set for checkpointing jobs. Contains path ckpt_dir
                      (see checkpoint(5) ) of the checkpoint interface.

       SGE_STDERR_PATH
                      the pathname of the file to  which  the  standard  error
                      stream  of  the  job  is  diverted.  Commonly  used  for
                      enhancing the output with error  messages  from  prolog,
                      epilog, parallel environment start/stop or checkpointing
                      scripts.

       SGE_STDOUT_PATH
                      the pathname of the file to which  the  standard  output
                      stream  of  the  job  is  diverted.  Commonly  used  for
                      enhancing the output with messages from prolog,  epilog,
                      parallel   environment   start/stop   or   checkpointing
                      scripts.

       SGE_STDIN_PATH the pathname of the file from which the  standard  input
                      stream  of the job is taken. This variable might be used
                      in combination with SGE_O_HOST in prolog/epilog  scripts
                      to  transfer  the  input  file  from  the  submit to the
                      execution host.

       SGE_JOB_SPOOL_DIR
                      The directory  used  by  sge_shepherd(8)  to  store  job
                      related  data  during  job  execution. This directory is
                      owned by root or by a  Sun  Grid  Engine  administrative
                      account  and  commonly  is  not  open  for read or write
                      access to regular users.

       SGE_TASK_ID    The index number of the current array job task  (see  -t
                      option  above).  This  is an unique number in each array
                      job and can be used to reference  different  input  data
                      records,  for  example. This environment variable is set
                      to "undefined" for non-array jobs.  It  is  possible  to
                      change  the predefined value of this variable with -v or
                      -V (see options above).

       SGE_TASK_FIRST The index number of the first array  job  task  (see  -t
                      option  above).  It is possible to change the predefined
                      value of this  variable  with  -v  or  -V  (see  options
                      above).

       SGE_TASK_LAST  The  index  number  of  the  last array job task (see -t
                      option above). It is possible to change  the  predefined
                      value  of  this  variable  with  -v  or  -V (see options
                      above).

       SGE_TASK_STEPSIZE
                      The step size of the array  job  specification  (see  -t
                      option  above).  It is possible to change the predefined
                      value of this  variable  with  -v  or  -V  (see  options
                      above).

       ENVIRONMENT    The  ENVIRONMENT  variable  is  set to BATCH to identify
                      that the job is being executed  under  Sun  Grid  Engine
                      control.

                      in the range 1 to 99999.

       JOB_NAME       The job name.  For batch jobs or jobs submitted by  qrsh
                      with a command, the job name is built as basename of the
                      qsub  script  filename  resp.  the  qrsh  command.   For
                      interactive  jobs  it  is  set  to ‘INTERACTIVE’ for qsh
                      jobs, ‘QLOGIN’ for qlogin jobs and  ‘QRLOGIN’  for  qrsh
                      jobs without a command.

                      This default may be overwritten by the -N.  option.

       SGE_BINARY_PATH
                      The  path  where  the  Sun  Grid  Engine  binaries   are
                      installed. The value is the concatenation of the cluster
                      configuration value  binary_path  and  the  architecture
                      name $SGE_ARCH environment variable.

       PE             The  parallel  environment  under which the job executes
                      (for parallel jobs only).

       PE_HOSTFILE    The path of a file  containing  the  definition  of  the
                      virtual  parallel  machine assigned to a parallel job by
                      Sun Grid Engine. See the description of the $pe_hostfile
                      parameter in sge_pe(5) for details on the format of this
                      file. The environment variable  is  only  available  for
                      parallel jobs.

       QUEUE          The  name  of  the  cluster  queue  in  which the job is
                      running.

       REQUEST        Available for batch jobs only.

                      The request name of a  job  as  specified  with  the  -N
                      switch  (see  above)  or  taken  as  the name of the job
                      script file.

       RESTARTED      This variable is set to 1 if a job was restarted  either
                      after  a  system crash or after a migration in case of a
                      checkpointing  job.  The  variable  has  the   value   0
                      otherwise.

       SHELL          The  user’s  login  shell from the passwd(5) file. Note:

       USER           The user’s login name from the passwd(5) file.

RESTRICTIONS

       There  is no controlling terminal for batch jobs under Sun Grid Engine,
       and any tests or actions on a controlling terminal will fail. If  these
       operations  are  in your .login or .cshrc file, they may cause your job
       to abort.

       Insert the following test before any commands that are not pertinent to
       batch jobs in your .login:

              if ( $?JOB_NAME) then
                     echo "Sun Grid Engine spooled job"
                     exit 0
              endif

       Don’t  forget  to  set  your shell’s search path in your shell start-up
       before this code.

EXIT STATUS

       The following exit values are returned:

       0    Operation was executed successfully.

       25   It was not possible  to  register  a  new  job  according  to  the
            configured  max_u_jobs  or  max_jobs limit. Additional information
            may be found in sge_conf(5)

       >0   Error occurred.

EXAMPLES

       The following is the simplest form of a Sun Grid Engine script file.

       =====================================================

       #!/bin/csh
          a.out

       =====================================================

       The next example is a more complex Sun Grid Engine script.

       =====================================================

       #!/bin/csh

       # Which account to be charged cpu time
       #$ -A santa_claus

       # date-time to run, format [[CC]yy]MMDDhhmm[.SS]
       #$ -a 12241200

       # to run I want 6 or more parallel processes
       # under the PE pvm. the processes require
       # 128M of memory
       #$ -pe pvm 6- -l mem=128

       # If I run on dec_x put stderr in /tmp/foo, if I
       # run on sun_y, put stderr in /usr/me/foo
       #$ -e dec_x:/tmp/foo,sun_y:/usr/me/foo

       # Send mail to these users
       #$ -M santa@nothpole,claus@northpole

       # Mail at beginning/end/on suspension
       #$ -m bes

       # Export these environmental variables
       #$ -v PVM_ROOT,FOOBAR=BAR

       # The job is located in the current
       # working directory.
       #$ -cwd
