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.
