Hi Robert: The tasks jobs are all submitted at the same time, and they also have SGE_TASK_ID environment variable set, which is VERY useful! Give it a try:
echo 'HOSTNAME=`hostname`; echo "this is task $SGE_TASK_ID on $HOSTNAME"' | qsub -N arraytest -t 1-4 -j y Use that SGE_TASK_ID to import options or data from a file or files, set a seed, etc. Task array jobs rule! :) -Hugh -----Original Message----- From: users-boun...@gridengine.org [mailto:users-boun...@gridengine.org] On Behalf Of Roberto Nunnari Sent: Wednesday, November 12, 2014 8:56 AM To: William Hay Cc: users@gridengine.org Subject: Re: [gridengine users] limit the number of jobs users can put on queue (pending) Il 12.11.2014 14:51, William Hay ha scritto: > On Wed, 12 Nov 2014 13:42:32 +0000 > Roberto Nunnari <roberto.nunn...@supsi.ch> wrote: > >> Il 12.11.2014 14:33, William Hay ha scritto: >>> On Wed, 12 Nov 2014 13:14:25 +0000 >>> Roberto Nunnari <roberto.nunn...@supsi.ch> wrote: >>> >>>> humm.. answering myself.. >>>> >>>> from the man pages it seams that >>>> >>>> maxujobs is for only running jobs per user >>>> >>>> while >>>> >>>> max_u_jobs is for both running and pending jobs per user >>>> >>>> is that correct? >>>> >>>> Thank you and best regards >>>> Robi >>> More or less.

Nice! :-) And the tasks in the array jobs can get running in parallel or they always run in serial?
