I found the job name is none and no results show up.
No shell prompt appear, the command line is hang there , no response.
Any help is appreciated.

I don't know if your site allows this, but interactive debugging here might be *significantly* easier than try to automate some debugging. > > > On Oct 25, 2010, at 1:35 PM, Jack Bryan wrote: > > > thanks > > > > I have to use #PBS to submit any jobs in my cluster. > > I cannot use command line to hang a job on my cluster. > > > > this is my script: > > -------------------------------------- > > #!/bin/bash > > #PBS -N jobname > > #PBS -l walltime=00:08:00,nodes=1 > > #PBS -q queuename > > COMMAND=/mypath/myprog > > NCORES=5 > > > > cd $PBS_O_WORKDIR > > NODES=`cat $PBS_NODEFILE | wc -l` > > NPROC=$(( $NCORES * $NODES )) > > > > mpirun -np $NPROC --mca btl self,sm,openib $COMMAND > > > > ------------------------------------------- > > > > Where should I put the (gdb --batch -ex 'bt full' -ex 'info reg' -pid ZOMBIE_PID) in the script ? > > And how to get ZOMBIE_PID from the script ? > > > > Any help is appreciated. > > > > thanks > > > > Oct. 25 2010 > > > > Date: Mon, 25 Oct 2010 19:24:35 +0200 > > From: firstname.lastname@example.org > > To: email@example.com > > Subject: Re: [OMPI users] Open MPI program cannot complete > > > > On Mon, Oct 25, 2010 at 19:07, Jack Bryan <firstname.lastname@example.org> wrote: > > I need to use #PBS parallel job script to submit a job on MPI cluster. > > > > Is it not possible to reproduce locally?
