DESCRIPTION

       To  create  a  job  is  to  submit  an executable script to a batch server.  The batch server will be the
       default server unless the -q option is  specified.   See  discussion  of  PBS_DEFAULT  under  Environment
       Variables  below.  Typically, the script is a shell script which will be executed by a command shell such
       as sh or csh.

       Options on the qsub command allow the specification of attributes which affect the behavior of the job.

       The qsub command will pass certain environment variables in  the  Variable_List  attribute  of  the  job.
       These  variables  will be available to the job.  The value for the following variables will be taken from
       the environment of the qsub command: HOME, LANG, LOGNAME, PATH, MAIL, SHELL, and TZ.  These  values  will
       be  assigned to a new name which is the current name prefixed with the string "PBS_O_".  For example, the
       job will have access to an environment variable named PBS_O_HOME which have the  value  of  the  variable
       HOME in the qsub command environment.

       In addition to the above, the following environment variables will be available to the batch job.

       PBS_O_HOST
              the name of the host upon which the qsub command is running.

       PBS_SERVER
              the hostname of the pbs_server which qsub submits the job to.

       PBS_O_QUEUE
              the name of the original queue to which the job was submitted.

       PBS_O_WORKDIR
              the absolute path of the current working directory of the qsub command.

       PBS_ARRAYID
              each member of a job array is assigned a unique identifier (see -t)

       PBS_ENVIRONMENT
              set  to PBS_BATCH to indicate the job is a batch job, or to PBS_INTERACTIVE to indicate the job is
              a PBS interactive job, see -I option.

       PBS_JOBID
              the job identifier assigned to the job by the batch system.

       PBS_JOBNAME
              the job name supplied by the user.

       PBS_NODEFILE
              the name of the file contain the list of nodes assigned to  the  job  (for  parallel  and  cluster
              systems).

       PBS_QUEUE
              the name of the queue from which the job is executed.

OPTIONS

       -a date_time
               Declares the time after which the job is eligible for execution.

               The date_time argument is in the form: [[[[CC]YY]MM]DD]hhmm[.SS]

               Where  CC  is  the first two digits of the year (the century), YY is the second two digits of the
               year, MM is the two digits for the month, DD is the day of the month, hh is the hour, mm  is  the
               minute, and the optional SS is the seconds.

               If the month, MM, is not specified, it will default to the current month if the specified day DD,
               is in the future.  Otherwise, the month will be set to next month.  Likewise, if the day, DD,  is
               not  specified,  it  will default to today if the time hhmm is in the future.  Otherwise, the day
               will be set to tomorrow.  For example, if you submit a job at 11:15am with a time of -a 1110, the
               job will be eligible to run at 11:10am tomorrow.

       -A account_string
               Defines the account string associated with the job.  The account_string is an undefined string of
               characters and is interpreted by the server which executes the job.  See section 2.7.1 of the PBS
               ERS.

       -b seconds
               Defines  the  maximum  number  of  seconds  qsub will block attempting to contact pbs_server.  If
               pbs_server is down, or for a variety of  communication  failures,  qsub  will  continually  retry
               connecting  to  pbs_server for job submission.  This value overrides the CLIENTRETRY parameter in
               torque.cfg.  This is a non-portable TORQUE  extension.   Portability-minded  users  can  use  the
               PBS_CLIENTRETRY  environmental  variable.   A  negative  value  is  interpreted as infinity.  The
               default is 0.

       -c checkpoint_options
               Defines the options that will apply to the job.  If the job executes upon a host which  does  not
               support checkpoint, these options will be ignored.

               Valid checkpoint options are:

               none
                  No checkpointing is to be performed.

               enabled
                  Specify  that  checkpointing  is allowed but must be explicitly invoked by either the qhold or
                  qchkpt commands.

               shutdown
                  Specify that checkpointing is to be done on a job at pbs_mom shutdown.

               periodic
                  Specify that periodic checkpointing is enabled. The default interval is 10 minutes and can  be
                  changed by the $checkpoint_interval option in the mom config file or by specifying an interval
                  when the job is submitted

               interval=minutes
                  Checkpointing is to be performed at an interval of minutes, which is  the  integer  number  of
                  minutes of wall time used by the job.  This value must be greater than zero.

               depth=number
                  Specify a number (depth) of checkpoint images to be kept in the checkpoint directory.

               dir=path
                  Specify a checkpoint directory (default is /var/spool/torque/checkpoint).

       -C directive_prefix
               Defines the prefix that declares a directive to the qsub command within the script file.  See the
               paragraph on script directives in the Extended Description section.

               If the -C option is presented with a directive_prefix argument that is the null string, qsub will
               not scan the script file for directives.

       -d path Defines  the  working  directory path to be used for the job.  If the -d option is not specified,
               the default working directory is the home directory.  This option sets the  environment  variable
               PBS_O_INITDIR.

       -D path Defines  the  root  directory  to be used for the job.  This option sets the environment variable
               PBS_O_ROOTDIR.

       -e path Defines the path to be used for the standard error stream of the batch job.  The path argument is
               of the form:
                   [hostname:][path_name]
               where hostname is the name of a host to which the file will be returned and path_name is the path
               name on that host in the syntax recognized  by  POSIX.   The  argument  will  be  interpreted  as
               follows:

               path_name
                      Where  path_name  is not an absolute path name, then the qsub command will expand the path
                      name relative to the current working directory of the command.  The  command  will  supply
                      the name of the host upon which it is executing for the hostname component.

               hostname:path_name
                      Where  path_name  is  not an absolute path name, then the qsub command will not expand the
                      path name relative to the current working directory of the command.  On  delivery  of  the
                      standard  error,  the  path name will be expanded relative to the user's home directory on
                      the hostname system.

               path_name
                      Where path_name specifies an absolute path name, then the qsub will supply the name of the
                      host on which it is executing for the hostname

               hostname:path_name
                      Where  path_name  specifies  an  absolute  path  name, the path will be used as specified.
                      hostname.

               hostname:
                      Where hostname specifies the name of the host that the file should  be  returned  to.  The
                      path will be the default file name.

               If  the  -e  option  is  not specified or the path_name is not specified or is specified and is a
               directory, the default file name for the standard error stream will be used.   The  default  name
               has the following form:
                   job_name.esequence_number
               where  job_name  is  the  name  of  the job, see -N option, and sequence_number is the job number
               assigned when the job is submitted.

       -f      Specifies that the job is fault tolerant. The fault_tolerant attribute will be set to true, which
               indicates  that  the  job can survive the loss of a mom other than the "mother superior" mom (the
               first node in the exec hosts )

       -h      Specifies that a user hold be applied to the job at submission time.

       -I      Declares that the job is to be run "interactively".  The job will be queued and scheduled as  any
               PBS  batch  job,  but when executed, the standard input, output, and error streams of the job are
               connected through qsub to the terminal session in which qsub is running.   Interactive  jobs  are
               forced  to  not  rerunable.  See the "Extended Description" paragraph for addition information of
               interactive jobs.

       -j join Declares if the standard error stream of the job will be merged with the standard  output  stream
               of the job.

               An  option  argument  value  of  oe  directs  that the two streams will be merged, intermixed, as
               standard output.  An option argument value of eo directs that the two  streams  will  be  merged,
               intermixed, as standard error.

               If  the  join  argument is n or the option is not specified, the two streams will be two separate
               files.

       -k keep Defines which (if either) of standard output or standard error will be retained on the  execution
               host.   If  set  for  a stream, this option overrides the path name for that stream.  If not set,
               neither stream is retained on the execution host.

               The argument is either the single letter "e" or "o", or the  letters  "e"  and  "o"  combined  in
               either order.  Or the argument is the letter "n".

               e  The standard error stream is to retained on the execution host.  The  stream will be placed in
                  the home directory of the user under whose user id the job executed.  The file  name  will  be
                  the  default  file  name given by: job_name.esequence where job_name is the name specified for
                  the job, and sequence is the sequence number component of the job identifier.

               o  The standard output stream is to retained on the execution host.  The  stream will  be  placed
                  in the home directory of the user under whose user id the job executed.  The file name will be
                  the default file name given by: job_name.osequence where job_name is the  name  specified  for
                  the job, and sequence is the sequence number component of the job identifier.

               eo Both the standard output and standard error streams will be retained.

               oe Both the standard output and standard error streams will be retained.

               n  Neither stream is retained.

       -l resource_list
               Defines  the  resources  that  are  required  by the job and establishes a limit to the amount of
               resource that can be consumed.  If not set for a generally available resource, such as CPU  time,
               the limit is infinite.  The resource_list argument is of the form:
                   resource_name[=[value]][,resource_name[=[value]],...]

       -m mail_options
               Defines the set of conditions under which the execution server will send a mail message about the
               job.  The mail_options argument is a string which consists of either the single character "n", or
               one or more of the characters "a", "b", and "e".

               If the character "n" is specified, no mail will be sent.

               For the letters "a", "b", and "e":

               a  mail is sent when the job is aborted by the batch system.

               b  mail is sent when the job begins execution.

               e  mail is sent when the job terminates.

               If the -m option is not specified, mail will be sent if the job is aborted.

       -M user_list
               Declares  the list of users to whom mail is sent by the execution server when it sends mail about
               the job.

               The user_list argument is of the form:
                   user[@host][,user[@host],...]
               If unset, the list defaults to the submitting user at the qsub host, i.e. the job owner.

       -N name Declares a name for the job.  The name specified may be up to  and  including  15  characters  in
               length.   It  must  consist  of  printable,  non  white space characters with the first character
               alphabetic.

               If the -N option is not specified, the job name will be the base name  of  the  job  script  file
               specified on the command line.  If no script file name was specified and the script was read from
               the standard input, then the job name will be set to STDIN.

       -o path Defines the path to be used for the standard output stream of the batch job.  The  path  argument
               is of the form:
                   [hostname:][path_name]
               where hostname is the name of a host to which the file will be returned and path_name is the path
               name on that host in the syntax recognized  by  POSIX.   The  argument  will  be  interpreted  as
               follows:

               path_name
                      Where  path_name  is not an absolute path name, then the qsub command will expand the path
                      name relative to the current working directory of the command.  The  command  will  supply
                      the name of the host upon which it is executing for the hostname component.

               hostname:path_name
                      Where  path_name  is  not an absolute path name, then the qsub command will not expand the
                      path name relative to the current working directory of the command.  On  delivery  of  the
                      standard  output,  the path name will be expanded relative to the user's home directory on
                      the hostname system.

               path_name
                      Where path_name specifies an absolute path name, then the qsub will supply the name of the
                      host on which it is executing for the hostname

               hostname:path_name
                      Where  path_name  specifies  an  absolute  path  name, the path will be used as specified.
                      hostname.

               hostname:
                      Where hostname specifies the name of the host that the file should  be  returned  to.  The
                      path will be the default file name.

               If  the  -o  option  is  not specified or the path_name is not specified or is specified and is a
               directory, the default file name for the standard output stream will be used.  The  default  name
               has the following form:
                   job_name.osequence_number
               where  job_name  is  the  name  of  the job, see -N option, and sequence_number is the job number
               assigned when the job is submitted.

       -p priority
               Defines the priority of the job.  The priority argument must be a integer between -1024 and +1023
               inclusive.  The default is no priority which is equivalent to a priority of zero.

       -P proxy_user[:group]
               Proxy  user  for  whom  the job should be submitted.  This option is only available for the super
               user.

       -q destination
               Defines the destination of the job.  The destination names a queue, a server, or  a  queue  at  a
               server.

               The  qsub  command  will submit the script to the server defined by the destination argument.  If
               the destination is a routing queue, the job may be routed by the server to a new destination.

               If the -q option is not specified, the qsub command will submit the script to the default server.
               See  PBS_DEFAULT under the Environment Variables section on this man page and the PBS ERS section
               2.7.4, "Default Server".

               If the -q option is specified, it is in one of the following three forms:
                   queue
                   @server
                   queue@server

               If the destination argument names a queue and does not name a server, the job will  be  submitted
               to the named queue at the default server.

               If  the  destination argument names a server and does not name a queue, the job will be submitted
               to the default queue at the named server.

               If the destination argument names both a queue and a server, the job will  be  submitted  to  the
               named queue at the named server.

       -r y|n  Declares  whether the job is rerunable.  See the qrerun command.  The option argument is a single
               character, either y or n.

               If the argument is "y", the job is rerunable.  If the argument is "n", the job is not  rerunable.
               The default value is 'y', rerunable.

       -S path_list
               Declares the shell that interprets the job script.

               The option argument path_list is in the form:
                   path[@host][,path[@host],...]
               Only  one  path  may be specified for any host named.  Only one path may be specified without the
               corresponding host name.  The path selected will be the one with the host name that  matched  the
               name of the execution host.  If no matching host is found, then the path specified without a host
               will be selected, if present.

               If the -S option is not specified, the option argument is the null string, or no entry  from  the
               path_list is selected, the execution will use the user's login shell on the execution host.

       -t array_request
               Specifies the task ids of a job array.  Single task arrays are allowed.

               The array_request argument is an integer id or a range of integers. Multiple ids or id ranges can
               be combined in a comma delimted list. Examples : -t 1-100 or -t 1,10,50-100

       -T script_name
               Allows for per job prologue and epilogue scripts. The full script name will be prologue.[name] or
               epilogue.[name].  For  the  job  submission,  only  request  the name of the prologue or epilogue
               script.

               Example: qsub -T prescript
               Specifies to use the script prologue.prescript

       -u user_list
               Defines the user name under which the job is to run on the execution system.

               The user_list argument is of the form:
                   user[@host][,user[@host],...]
               Only one user name may be given per specified host.  Only one of the user specifications  may  be
               supplied without the corresponding host specification.  That user name will used for execution on
               any host not named in the argument list.  If unset, the user list defaults to  the  user  who  is
               running qsub.

       -v variable_list
               Expands the list of environment variables that are exported to the job.

               In  addition  to  the variables described in the "Description" section above, variable_list names
               environment variables from the qsub command environment which are made available to the job  when
               it  executes.   The  variable_list  is  a comma separated list of strings of the form variable or
               variable=value.  These variables and their values are passed to the job.

       -V      Declares that all environment variables in the qsub command's environment are to be  exported  to
               the batch job.

       -w path Defines  the  working  directory path to be used for the job.  If the -w option is not specified,
               the default working directory is  the  current  directory.   This  option  sets  the  environment
               variable PBS_O_WORKDIR.

       -W additional_attributes
               The  -W  option allows for the specification of additional job attributes.  The general syntax of
               the -W is in the form:
                   -W attr_name=attr_value[,attr_name=attr_value...]
               Note if white space occurs anywhere within the option argument string or  the  equal  sign,  "=",
               occurs  within  an attribute_value string, then the string must be enclosed with either single or
               double quote marks.

               PBS currently supports the following attributes within the -W option.

               depend=dependency_list
               Defines the dependency between this and other jobs.  The dependency_list is in the form:
               type[:argument[:argument...][,type:argument...].
               The argument is either a numeric count or a PBS job id according to type  .   If  argument  is  a
               count,  it  must  be  greater  than  0.   If  it  is a job id and not fully specified in the form
               seq_number.server.name, it will be expanded according to the default server rules which apply  to
               job  IDs  on most commands.  If argument is null (the preceding colon need not be specified), the
               dependency of the corresponding type is cleared (unset).

                   synccount:count
                       This job is the first in a set of jobs to be executed at the same  time.   Count  is  the
                       number of additional jobs in the set.

                   syncwith:jobid
                       This  job  is  an additional member of a set of jobs to be executed at the same time.  In
                       the above and following dependency types, jobid is the job identifier of the first job in
                       the set.

                   after:jobid[:jobid...]
                       This  job  may  be  scheduled  for  execution  at any point after jobs jobid have started
                       execution.

                   afterok:jobid[:jobid...]
                       This job may be scheduled for execution only after jobs jobid  have  terminated  with  no
                       errors.  See the csh warning under "Extended Description".

                   afternotok:jobid[:jobid...]
                       This  job  may  be  scheduled  for  execution  only after jobs jobid have terminated with
                       errors.  See the csh warning under "Extended Description".

                   afterany:jobid[:jobid...]
                       This job may be scheduled for execution after jobs jobid have terminated, with or without
                       errors.

                   on:count
                       This  job may be scheduled for execution after count dependencies on other jobs have been
                       satisfied.  This form is used in conjunction with one of the before forms, see below.

                   before:jobid[:jobid...]
                       When this job has begun execution, then jobs jobid... may begin.

                   beforeok:jobid[:jobid...]
                       If this job terminates execution without errors, then jobs jobid... may begin.   See  the
                       csh warning under "Extended Description".

                   beforenotok:jobid[:jobid...]
                       If  this job terminates execution with errors, then jobs jobid... may begin.  See the csh
                       warning under "Extended Description".

                   beforeany:jobid[:jobid...]
                       When this job terminates execution, jobs jobid... may begin.

                       If any of the before forms are  used,  the  jobs  referenced  by  jobid  must  have  been
                       submitted with a dependency type of on.

                       If  any  of  the  before  forms are used, the jobs referenced by jobid must have the same
                       owner as the job being submitted.  Otherwise, the dependency is ignored.

                   Error processing of the existence, state,  or  condition  of  the  job  on  which  the  newly
                   submitted job is a deferred service, i.e. the check is performed after the job is queued.  If
                   an error is detected, the new job will be deleted by the server.  Mail will be  sent  to  the
                   job submitter stating the error.

                   Dependency examples:
                   qsub -W depend=afterok:123.big.iron.com /tmp/script
                   qsub -W depend=before:234.hunk1.com:235.hunk1.com /tmp/script

               group_list=g_list
               Defines  the  group  name  under  which  the  job  is to run on the execution system.  The g_list
               argument is of the form:
               group[@host][,group[@host],...]
               Only one group name may be given per specified host.  Only one of the group specifications may be
               supplied  without  the corresponding host specification.  That group name will used for execution
               on any host not named in the argument list.  If not set, the group_list defaults to  the  primary
               group of the user under which the job will be run.

               interactive=true
               If  the  interactive  attribute  is specified, the job is an interactive job.  The -I option is a
               alternative method of specifying this attribute.

               stagein=file_list
               stageout=file_list
               Specifies which files are staged (copied) in before  job  start  or  staged  out  after  the  job
               completes  execution.   On  completion of the job, all staged-in and staged-out files are removed
               from the execution system.  The file_list is in the form
               local_file@hostname:remote_file[,...]
               regardless of the direction of the copy.  The name local_file is the name  of  the  file  on  the
               system  where  the job executed.  It may be an absolute path or relative to the home directory of
               the user.  The name remote_file is the destination name on the host specified by  hostname.   The
               name  may  be absolute or relative to the user's home directory on the destination host.  The use
               of wildcards in the file name is not recommended.  The file names map to a  remote  copy  program
               (rcp) call on the execution system in the follow manner:
               For stagein:   rcp hostname:remote_file local_file
               For stageout:  rcp local_file hostname:remote_file
               Data staging examples:
               -W stagein=/tmp/input.txt@headnode:/home/user/input.txt
               -W stageout=/tmp/output.txt@headnode:/home/user/output.txt
               If  TORQUE  has  been  compiled with wordexp support, then variables can be used in the specified
               paths.  Currently only $PBS_JOBID, $HOME, and $TMPDIR are supported for stagein.

               umask=XXX
               Sets umask used to create stdout and stderr  spool  files  in  pbs_mom  spool  directory.  Values
               starting  with  0  are treated as octal values, otherwise the value is treated as a decimal umask
               value.

       -x      When running an interactive job, the -x flag makes it so that the script won't be parsed for  PBS
               directives,  but instead will be a command that is launched once the interactive job has started.
               The job will terminate at the completion of this command.

       -X      Enables X11 forwarding.  The DISPLAY environment variable must be set.

       -z      Directs that the qsub command is not to write the job identifier  assigned  to  the  job  to  the
               command's standard output.

OPERANDS

       The  qsub  command  accepts  a  script operand that is the path to the script of the job.  If the path is
       relative, it will be expanded relative to the working directory of the qsub command.

       If the script operand is not provided or the operand is the single character "-", the qsub command  reads
       the  script  from  standard input.  When the script is being read from Standard Input, qsub will copy the
       file to a temporary file.  This temporary file is passed to the  library  interface  routine  pbs_submit.
       The  temporary  file  is  removed  by qsub after pbs_submit returns or upon the receipt of a signal which
       would cause qsub to terminate.

STANDARD INPUT

       The qsub command reads the script for the job from standard input if the script operand is missing or  is
       the single character "-".

INPUT FILES

       The script file is read by the qsub command.  Qsub acts upon any directives found in the script.

       When the job is created, a copy of the script file is made and that copy cannot be modified.

STANDARD OUTPUT

       Unless the -z option is set, the job identifier assigned to the job will be written to standard output if
       the job is successfully created.

STANDARD ERROR

       The qsub command will write a diagnostic message to standard error for each error occurrence.

ENVIRONMENT VARIABLES

       The values of some or all of the variables in the qsub command's environment are exported with  the  job,
       see the -v and -V options.

       The  environment variable PBS_DEFAULT defines the name of the default server.   Typically, it corresponds
       to the system name of the host on which the server is running.  If PBS_DEFAULT is not set, the default is
       defined by an administrator established file.

       The  environment  variable  PBS_DPREFIX  determines  the prefix string which identifies directives in the
       script.

       The environment variable PBS_CLIENTRETRY defines the maximum number of seconds qsub will block.  See  the
       -b option above.  Despite the name, currently qsub is the only client that supports this option.

TORQUE.CFG

       The  torque.cfg  file, located in PBS_SERVER_HOME (/var/spool/torque by default) controls the behavior of
       the qsub command. This file contains a list of parameters and values separated by whitespace

       QSUBSLEEP takes an integer operand which specifies time to sleep when  running  qsub  command.   Used  to
       prevent users from overwhelming the scheduler.

       SUBMITFILTER specifies the path to the submit filter used to pre-process job submission. The default path
       is $(libexecdir)/qsub_filter, which  falls  back  to  /usr/local/sbin/torque_submitfilter  for  backwards
       compatibility. This torque.cfg parameter overrides this default.

       SERVERHOST specifies the value for the PBS_SERVER environment variable

       QSUBHOST specifies the hostname for the jobs QSUB_O_HOST variable

       QSUBSENDUID specifies a uid to use for the jobs PBS_O_UID variable

       XAUTHPATH specifies the path to xauth

       CLIENTRETRY specifies the integer seconds between retry attempts to communicate with pbs_server

       VALIDATEGROUP set this parameter to force qsub to verify the submitter's group id

       DEFAULTCKPT  specifies the default value for the jobs checkpoint attribute.  The user overrides this with
       the -c qsub option.

       VALIDATEPATH set this parameter to force qsub to validate local existence of a "-d" working directory

       RERUNNABLEBYDEFAULT this parameter specifies if a job is rerunnable by  default.  The  default  is  true,
       setting  this  to  false  causes  the  rerunnable  attribute value to be false unless the users specifies
       otherwise with the -r option

       FAULT_TOLERANT_BY_DEFAULT this parameter specifies if a job is fault tolerant by  default.   The  default
       value  for  the  fault_tolerant job attribute is false, setting this parameter to true causes the default
       value of the attribute to be true. The user can specify their preference with the -f qsub option.

       For example:
              QSUBSLEEP  2
              RERUNNABLEBYDEFAULT  false

EXTENDED DESCRIPTION

       Script Processing:

       A job script may consist of PBS directives, comments and executable statements.  A PBS directive provides
       a way of specifying job attributes in addition to the command line options.  For example:
              :
              #PBS -N Job_name
              #PBS -l walltime=10:30,mem=320kb
              #PBS -m be
              #
              step1 arg1 arg2
              step2 arg3 arg4

       The  qsub  command scans the lines of the script file for directives.  An initial line in the script that
       begins with the characters "#!" or the character ":" will be ignored and scanning  will  start  with  the
       next line.  Scanning will continue until the first executable line, that is a line that is not blank, not
       a directive line, nor a line whose first non white space  character  is  "#".   If  directives  occur  on
       subsequent lines, they will be ignored.

       A  line  in  the  script  file  will  be  processed  as  a directive to qsub if and only if the string of
       characters starting with the first non white space character on the line and of the same  length  as  the
       directive prefix matches the directive prefix.

       The  remainder of the directive line consists of the options to qsub in the same syntax as they appear on
       the command line.  The option character is to be preceded with the "-" character.

       If an option is present in both a directive and on the command line, that option  and  its  argument,  if
       any, will be ignored in the directive.  The command line takes precedence.

       If an option is present in a directive and not on the command line, that option and its argument, if any,
       will be processed as if it had occurred on the command line.

       The directive prefix string will be determined in order of preference from:

           The value of the -C option argument if the option is specified on the command line.

           The value of the environment variable PBS_DPREFIX if it is defined.

           The four character string #PBS.

       If the -C option is found in a directive in the script file, it will be ignored.

       User Authorization:

       When the user submits a job from a system other than the one on which the PBS Server is running, the name
       under which the job is to be executed is selected according to the rules listed under the -u option.  The
       user submitting the job must be  authorized  to  run  the  job  under  the  execution  user  name.   This
       authorization is provided if

              (1)  The host on which qsub is run is trusted by the execution host (see /etc/hosts.equiv),

              (2)  The execution user has an .rhosts file naming the submitting user on the submitting host.

       C-Shell .logout File:

       The  following warning applies for users of the c-shell, csh.  If the job is executed under the csh and a
       .logout file exists in the home directory in which the job executes, the exit status of the job  is  that
       of  the .logout script, not the job script.  This may impact any inter-job dependencies.  To preserve the
       job exit status, either remove the .logout file or place the following line as  the  first  line  in  the
       .logout file
          set EXITVAL = $status
       and the following line as the last executable line in .logout
          exit $EXITVAL

       Interactive Jobs:

       If  the  -I option is specified on the command line or in a script directive, or if the "interactive" job
       attribute declared true via the -W option, -W interactive=true, either on the command line or in a script
       directive,  the  job is an interactive job.  The script will be processed for directives, but will not be
       included with the job.  When the job begins execution, all input to the job is from the terminal  session
       in which qsub is running.

       When  an  interactive  job  is  submitted, the qsub command will not terminate when the job is submitted.
       Qsub will remain running until the job terminates, is aborted, or the user interrupts qsub with an SIGINT
       (the  control-C  key).   If  qsub  is interrupted prior to job start, it will query if the user wishes to
       exit.  If the user response "yes", qsub exits and the job is aborted.

       Once the interactive job has started execution, input to and output  from  the  job  pass  through  qsub.
       Keyboard  generated  interrupts  are  passed  to  the job.  Lines entered that begin with the tilde ('~')
       character and contain special sequences are escaped by qsub.  The recognized escape sequences are:

              ~.     Qsub terminates execution.  The batch job is also terminated.

              ~susp  Suspend the qsub program if running under the C shell.  "susp" is  the  suspend  character,
                     usually CNTL-Z.

              ~asusp Suspend  the  input  half  of  qsub  (terminal  to job), but allow output to continue to be
                     displayed.  Only works under the C shell.  "asusp"  is  the  auxiliary  suspend  character,
                     usually CNTL-Y.

EXIT STATUS

       Upon successful processing, the qsub exit status will be a value of zero.

       If the qsub command fails, the command exits with a value greater than zero.
