NAME

       oarsub - OAR job submission command.

SYNOPSIS

       oarsub [OPTIONS] <command>

       oarsub [OPTIONS] -I

       oarsub [OPTIONS] -r "<START DATE|now>[, <END DATE>]" [<command>]

       oarsub [OPTIONS] -C [<JOB ID>]

DESCRIPTION

       One uses oarsub to submit a job to the OAR resources and jobs management system.  A job is
       defined by a command to run and optionally the description of a set of wanted resources to
       execute a task.  The command can be any executable program or script file, or a script
       command line.

       The OAR scheduler is in charge of providing a set of resources which matches the oarsub
       resource request (see the -l option). Once scheduled and launched, the job executes the
       command on the first node (machine) of the assigned resources, with some environment
       variables set (e.g. the assigned resources list, the job duration a.k.a walltime, ...). If
       many nodes (machines) are assigned to the job, it is let to the user's command to dispatch
       an execution on all nodes.

       OAR defines two kinds of jobs: batch jobs and advance reservation jobs.

   BATCH JOBS
       A batch job lets the OAR scheduler decide when to execute the job, depending on when the
       requested resources are available. If not using the -I option, oarsub returns immediately:
       the job is queued (use the oarstat command to list the queued jobs). When using the -I
       option, oarsub waits until the job can start then opens a interactive shell on the first
       of the assigned nodes.

   ADVANCE RESERVATION JOBS
       Calling oarsub with the -r option creates an advance reservation job instead of a batch
       job. An advance reservation job lets the user decide when the job should start (and
       optionally end). oarsub waits for a validation of the resources availability. Whether a
       set of resources matching the resource request of the job is available, an OK or KO
       message is returned. OK means that the job will run at the requested date. KO means that
       the job is refused.

OPTIONS

       -I, --interactive
           Request an interactive job.

       -C, --connect [<JOB ID>]
           Connect to a running job. Job id may be omitted if only one job is running.

       -l, --resource <DESCRIPTION>[,<WALLTIME>]
           Set the description of the requested resources for the job and a walltime which
           specifies an estimation of the maximum duration of the job (the job process can
           terminate earlier).  The walltime format is hours:minutes:seconds (seconds and minutes
           can be omitted).

             oarsub -l /host=4/cpu=1,walltime=2:00:00

           Multiple -l options can be given to define a moldable job: a job accepting different
           combination of resource definitions. Example:

             oarsub -l cpu=2,walltime=20:00:00 -l cpu=4,walltime=10:00:00 -l cpu=8,walltime=5:00:00 ./script.sh

           OAR will allocate resources to the job accordingly to one of the 3 given definitions
           depending of the load of the cluster, and preferring earliest possible start.

           One can also request different groups of resources, for example:

             oarsub -l "{mem > 64}/host=1+{mem < 48}/host=3",walltime=1:00:00 -I

           The job requests to run on 1 host with the property "mem" > 64 and 3 hosts with
           property "mem" < 48.  The syntax between braces, {...}, is the same as the one used
           for -p option.

       --array <NUMBER>
           Submit an array job containing "NUMBER" subjobs. All the subjobs share the same
           array_id but each subjob is independent and has its own job_id. All the subjobs have
           the same characteristics (script, requirements) and can be identified by an
           environment variable $OAR_ARRAY_INDEX.

           Array jobs can neither be Interactive (-I) nor a reservation (-r).

       --array-param-file <FILE>
           Submit a parametric array job. Each non-empty line of "FILE" defines the parameters
           for a subjob. All the subjobs have the same characteristics (script, requirements) and
           can be identified by an environment variable $OAR_ARRAY_INDEX.   '#' is the comment
           sign.

           Parametric array jobs can neither be Interactive (-I) nor a reservation (-r).

       -S, --scanscript
           Request oarsub to scan the script file given as the job command, for extra options to
           apply to the job (lines starting with #OAR)

       -q, --queue <QUEUE>
           Set the queue to submit the job to.

       -p, --property "<SQL WHERE CLAUSE>"
           Add constraints to the wanted resource for the job, using the resources properties.
           Constraints use the SQL WHERE CLAUSE syntax.

       -r, --reservation "<START DATE|now>[, <END DATE>]"
           Request that the job starts (and optionally ends) at a specified time. Using this
           option, the job is called an advance reservation.

           Start and end dates use the YYYY-MM-DD hh:mm:ss format. If YYYY-MM-DD is omitted, it
           defaults to the current day. In hh:mm:ss, ss and mm can be omitted. Quotes are only
           required when spaces are present.  When an end date is provided the job walltime is
           inferred, unless provided in the -l resources request which prevails. The special
           keyword now can be used as the start date to request an advance reservation job that
           starts just now.

       --checkpoint <DELAY>
           Enable the checkpointing mechanism for the job.  A signal will be sent DELAY seconds
           before the walltime to the first processus of the job (on the first node of the job
           resources).

       --signal <#SIG>
           Specify the signal to used to trigger the checkpointing. Use signal numbers (see kill
           -l), default is 12 (SIGUSR2).

       -t, --type <TYPE>
           Specify a specific type (besteffort, timesharing, idempotent, cosystem, deploy, noop,
           container, inner, token:xxx=yy,... )

           Notes:
             - a job with the besteffort type will be scheduled with the lowest priority and will
           be killed if a "normal" job needs its resources.
             - a job with the idempotent type will be automatically resubmitted if its exit code
           is 99 and its duration > 60s.
             - a job with the idempotent and besteffort types but with no checkpoint delay will
           automatically be resubmitted whenever killed by OAR before its normal termination to
           execute a non-besteffort jobs.
             - a job with the idempotent and besteffort types with a checkpoint delay will be
           automatically resubmitted if its exit code is 99 and its duration > 60s (that is, as
           if only idempotent was present).
             - a job with the noop type does nothing except reserving the resources. It is ended
           at the end of it walltime or when using the oardel command.

           The -t option can be used several times to provide different job types to the job.

       -d, --directory <DIR>
           Specify the directory where to launch the command (default is current directory)

       --project <TXT>
           Specify a name of a project the job belongs to.

       -n, --name <TXT>
           Specify an arbitrary name for the job.

       -a, --anterior <OAR JOB ID>
           Previously submitted job that the new job execution must depend on. The new job will
           only start upon the end of the previous one.

       --notify <TXT>
           Specify a notification method (email or command to execute).  Ex:
            --notify "mail:name@domain.com"
            --notify "exec:/path/to/script args"

           Arguments are job_id, job_name, TAG, comment

           TAG can be:
             - RUNNING: when the job is launched
             - END: when the job is finished normally
             - ERROR: when the job is finished abnormally
             - INFO: used when oardel is called on the job
             - SUSPENDED: when the job is suspended
             - RESUMING: when the job is resumed

           By default all TAGs are triggered. It is possible to specify which TAGs must be
           triggered.  Ex:
            --notify "[END,ERROR]mail:name@domain.com"
            --notify "[RUNNING]mail:name@domain.com"
            --notify "[RUNNING,END,ERROR]exec:/path/to/script args"

       --resubmit <OAR JOB ID>
           Resubmit the given job as a new one.

       -k, --use-job-key
           Activate the job-key mechanism: a job-key will be generated for the job, which can be
           used my the oarsh command in place of the OAR_JOB_ID. That job-key also allows one to
           connect to a job from a machine which is outside the OAR cluster the job belong to
           (e.g. in a grid of OAR clusters), given the job-key is available on that machine.

           The job-key mechanism may be activated by default in the configuration of your OAR
           cluster. In that case, the -k option is useless.

           Please note that this option is mostly useful when used together with the -e option or
           the -i option (see below).

       -e, --export-job-key-to-file
           Export the job-key to a file (the %jobid% pattern is automatically replaced in the
           filename). Warning: the file will be overwritten, whenever it already exists.

       -i, --import-job-key-from-file
           Import the job-key to use (you may reuse an exported job-key from a previous job for
           instance) from a file, instead of generating a new one. One may also use the
           OAR_JOB_KEY_FILE environment variable to set the job-key file.

       --import-job-key-inline
           Import the job-key to use inline (as text in the command line), instead of generating
           a new one.

       -O <FILE>
           Specify the file that will store the standard output stream of the job. The %jobid%
           and %jobname% patterns are automatically replaced.

       -E <FILE>
           Specify the file that will store the standard error stream of the job. The %jobid% and
           %jobname% patterns are automatically replaced.

       --hold
           Set the job state into Hold instead of Waiting, so that it is not scheduled as long as
           not resumed (the oarresume command allows one to turn it back into the Waiting state).

       -D, --dumper
           Print the command results in Perl's Data::Dumper format.

       -X, --xml
           Print the command results in the XML format.

       -Y, --yaml
           Print the command results in the YAML format.

       -J, --json
           Print the command results in the JSON format.

       -h, --help
           Print this help message.

       -V, --version
           Print the version of OAR.

       -v  Verbose mode, oarsub and admissions rules (if compatible) will print more information
           on terminal. Multiple -v can be used to increase the level of verbosity (max: 2).

ENVIRONMENT

       OAR_FILE_NODES or OAR_NODE_FILE or OAR_NODEFILE
           Pathname to the file containing the list of the nodes that are assigned to the job.

       OAR_JOB_NAME
           Name of the job as given using the -n option.

       OAR_JOB_ID or OAR_JOBID
           Id of the job. Each job get a unique job identifier. This identifier can be use to
           retrieve information about the job using oarstat, or to connect to a running job using
           oarsub -C or oarsh for instance.

       OAR_ARRAY_ID or OAR_ARRAYID
           Array Id of the job. Every array job gets an unique array identifier that is shared by
           all the subjobs of the array job. This identifier can be used to identify the
           different subjobs pertaining to a same array job. Array Id can also be used to deal
           with all the subjobs of a given array at once (by means of the --array  option in the
           case of oarstat, oarhold, oarresume and oardel). NB: regular jobs are array jobs with
           only one subjob.

       OAR_JOB_INDEX or OAR_JOBINDEX
           Array Index of the job: within an array job, each subjob gets a unique (for a given
           array) index, starting from 0, which can be used to identify the subjob.

       OAR_JOB_WALLTIME and OAR_JOB_WALLTIME_SECONDS
           Walltime of the job in the hh:mm:ss format and in seconds.

       OAR_RESOURCE_PROPERTIES_FILE
           Pathname to the file containing the list of all resources assigned for the job, and
           their value. See oarprint also.

       OAR_PROJECT_NAME
           Name of the project the job is part of, as given using the --project option.

       OAR_STDOUT and OAR_STDERR
           Pathname to the files storing the standard output and standard error of the job
           executable, if not running in interactive mode.

       OAR_WORKING_DIRECTORY aka OAR_WORKDIR aka OAR_O_WORKDIR
           Working directory for the job. The job executable will be executed in that directory,
           on the first node which is allocated to the job.

       OAR_JOB_KEY_FILE
           Key file to use for the submission (or oarsh) if using the job-key mechanism (-k or
           --use-job-key option). One may provide the job-key to import using the -i or
           --import-job-key-from-file option as well.

SCRIPT

       When submitting a job using a script file, that script file can contain some extra OAR
       options, with lines starting with #OAR and using the same option syntax as described
       above.

EXAMPLES

   Job submission with arguments
        oarsub -l /nodes=4 -I

        oarsub -q default -l /nodes=10/cpu=3,walltime=50:30:00 -p "switch = 'sw1'" /home/username/path/to/my/prog

        oarsub -r "2009-04-27 11:00:00" -l /nodes=12/cpu=2

        oarsub -C 154

   Array job submission with 10 identical subjobs
        oarsub -l /nodes=4 /home/usename/path/to/my/prog --array 10

   Parametric array job submission
        oarsub /home/users/toto/prog --array-param-file /home/username/path/to/params.txt

       With /home/username/path/to/param.txt containing for instance:

        # my param file
        # a subjob with a single parameter
        p100
        # a subjob without parameter
        ""
        # a subjob with two strings as parameters
        "arg1a arg1b arg1c" "arg2a arg2b"

   Job submission with a job script
        oarsub -S /home/username/path/to/my/script.sh

       With /home/username/path/to/my/script.sh containing for instance:

        #!/bin/bash
        #OAR -l /nodes=4/cpu=1,walltime=3:15:00
        #OAR -p switch = 'sw3' or switch = 'sw5'
        #OAR -t besteffort
        #OAR -t type2
        #OAR -k
        #OAR -e /path/to/job/key
        #OAR --stdout stdoutfile.log
        /home/username/path/to/my/prog
