NAME

       qrsub   - Submit an Advance Reservation (AR) to Grid Engine.

SYNTAX

       qrsub  [-a  date_time] [-A account_string] [-ckpt ckpt_name] [-d time] [-e date_time] [-he
       yes|no] [-help] [-l resource_list] [-now] [-M user[@host],...]  [-N ar_name] [-w e|v] [-pe
       pe_name slot_range] [-q wc_queue_list] [-u wc_user_list]

DESCRIPTION

       Qrsub  provides  a  means  for  operators,  managers  or  users referenced in the ACL (see
       access_list(5)) "arusers" to create an Advance Reservation (AR) in the Grid Engine queuing
       system. ARs allow reserving particular consumable resources for future use. These reserved
       resources are only available for jobs requesting the AR, and  the  scheduler  ensures  the
       availability  of  the resources when the start time is reached. Jobs requesting the AR can
       only use the reserved consumable resources.

       During AR submit time the Grid Engine queuing system selects the best  suited  queues  for
       the  AR request and then reserves the desired amount of resources.  For a reservation, all
       queues that are not in orphaned state are considered as suited. Only if the AR request can
       be fulfilled will the AR be granted.

       ARs  will  be deleted either automatically when the end time is reached, or manually using
       qrdel(1).  In both cases, first all jobs requesting the AR will be removed and then the AR
       itself. Already granted ARs can be shown with qrstat(1).

       Note:  To  make  AR  behavior  predictable,  it  is  necessary  to have reserved resources
       available at the time of AR start. This is done by keeping jobs with a  unlimited  runtime
       limit separated from ARs, and not considering resources used by such jobs for reservation.

       Note:  Resource  Quotas are not considered for AR queue selection, nor for jobs requesting
       an AR.

       When an AR was successfully added to the Grid Engine queuing system qrsub returns a unique
       integer  ID  referring  to  the the newly created AR. The highest AR ID is 9999999. If the
       highest ID is reached, a wraparound happens and the next unused ID, starting with 1,  will
       be used.

       For  qrsub,  the administrator and the user may define default request files (analogous to
       Grid Engine_request for qsub), which can contain any of the possible command line options.
       A cluster wide default request file is optional.  If such a default request file is  used,
       it must be placed under
       $SGE_ROOT/$SGE_CELL/common/sge_ar_request (global defaults file).
       A user private default request file is optional. If it is used, it must be placed under
       $HOME/.sge_ar_request (user private defaults file).

OPTIONS

       -a date_time
              Defines  the  activation  (start)  date  and  time  of  an  AR.   The option is not
              mandatory. If omitted, the current date_time is assumed. Either a duration  or  end
              date_time  must  also  be specified. For details of the date_time definition please
              see sge_types(5).

       -A account_string
              Identifies the account to which the  resource  reservation  of  the  AR  should  be
              charged.  For  "account_string"  value  details please see the "name" definition in
              sge_types(5).  In the absence of this parameter Grid Engine will place the  default
              account string "sge" in the accounting record of the AR.

       -ckpt ckpt_name
              Selects  the checkpointing environment (see checkpoint(5)) the AR jobs may request.
              Using this option guarantees that only queues providing this checkpoint environment
              will be reserved.

       -d date_time
              Defines  the  duration  of the AR. The use of "-d" is optional if "-e date_time" is
              requested.  For details of the "date_time" definition please see sge_types(5).

       -e date_time
              Defines the end date and time of an AR. The use of "-e date_time"  is  optional  if
              "-d  time"  is  requested.   For  details  about  "date_time" definition please see
              sge_types(5).

       -he y[es]|n[o]
              Specifies the behavior when the AR goes into an error state. The AR goes into error
              state  when a reserved host goes into unknown state, a queue error happens, or when
              a queue is disabled or suspended.

              A hard error, "-he yes", means as long as the AR is in error state  no  jobs  using
              the  AR  will  be  scheduled.   If  soft error, "-he no", is specified the AR stays
              usable with the remaining resources.
              By default soft error handling is used.

       -help  Prints a list of all options.

       -l resource=value,...
              Creates an AR in a Grid Engine queue, providing the given  resource  request  list.
              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.

       -m b|e|a|n
              Defines or redefines under which circumstances mail is to be sent to the  AR  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 AR
              e     Mail is sent at the end of the AR
              a     Mail is sent when the AR goes into error state
              n     No mail is sent, default for qrsub

       -M user[@host],...
              Defines or redefines the list of users to which the qmaster sends mail.

       -masterq wc_queue_list
              Only meaningful for a parallel AR request together with the -pe option.

              This option is used to reserve the proper queues to match this request if it  would
              be  requested by a qsub.  A more detailed description of wc_queue_list can be found
              in sge_types(5).

       -now y[es]|n[o]
              This option affects the queue selection for reservation.
              With the "-now y" option, only queues with the qtype "INTERACTIVE" assigned will be
              considered for reservation.  "-now n" is the default for qrsub.

       -N name
              The  name  of  the AR. The name, if requested, must conform to "name" as defined in
              sge_types(5).  Invalid names will be denied at submit time.

       -w e|v Specifies the validation level applied to the AR request.

              The specifiers e and v define the following validation modes:

              v    verify - does not submit the AR but prints
                   an extensive validation report
              e    error - rejects request if requirements cannot
                   be fulfilled, default for qrsub

       -pe parallel_env n[-[m]]|[-]m,...
              Parallel programming environment (PE) to  select  for  the  AR  queue  reservation.
              Please see the details of a PE in sge_pe(5).

       -q wc_queue_list
              Defines  or  redefines  a  list of cluster queues, queue domains or queue instances
              that may be reserved by the AR. Please  find  a  description  of  wc_queue_list  in
              sge_types(5).  This parameter has all the properties of a resource request and will
              be merged with requirements derived from the -l option described above.

       -u [username|@access_list],...
              Defines the users allowed to submit jobs requesting the AR. The access is specified
              by  a  comma-separated list containing UNIX users or ACLs (see access_list(5)).  An
              ACL is differentiated from a UNIX user name by prefixing the ACL name with  an  '@'
              sign.
              By default only the AR owner is allowed to submit jobs requesting the AR.

              Note:  Only queues where all users specified in the list have access are considered
              for reservation (see queue_conf(5)).

ENVIRONMENT VARIABLES

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

       SGE_CELL       If set, specifies the default Grid Engine cell. To address  a  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 of defining the port.
