NAME

       qevent - subscribe and respond to Grid Engine events

DESCRIPTION

       qevent  subscribes to "events" generated by the Grid Engine system and loops after writing its pid to the
       file qevent.pid.  It is used by the Grid Engine test suite, and otherwise can be used to wait for  a  job
       or task to finish more efficiently than running qstat in a loop.  See the example below.

SYNOPSIS

       qevent [-h|-help] [-ts|-testsuite] [-sm|-subscribe] [-trigger event script [-trigger event script],...]

OPTIONS

       -h, -help
              Show usage

       -ts, -testsuite
              Run in test suite mode.

       -sm, -subscribe
              Run in subscribe mode, printing events from the system.

       -trigger event script
              Start executable script when the specified event occurs.  script gets three arguments: event name,
              job id, and task id.  event is one of JB_END: signals a job end; JB_TASK_END: signals a  job  task
              end.

FILES

       qevent.pid
              Id of the qevent process.

EXAMPLE

       This  is  an  example  of  waiting for a job which could be used if the -sync, -hold_jid, or -hold_jid_ad
       options of qsub aren't sufficient.

           $ cat wait-for-job
           #!/bin/sh
           if [ "$2" = $JOBID ]; then
               echo Job $JOBID finished
               kill $(cat qevent.pid)
               exit 0
           fi
           $ export JOBID=`qsub -b y -terse sleep 30`
           $ qevent -trigger JB_END ./wait-for-job
           Job 122837 finished
           $

BUGS

       Needs tidying up and extending.
