I have to use #PBS to submit any jobs in my cluster.
I cannot use command line to hang a job on my cluster.
You don't need a cluster to run MPI jobs, can you run the job on whatever you development machine is? Does it hang there?
PBS interactive jobs are started with qsub -I.
Where should I put the (gdb --batch -ex 'bt full' -ex 'info reg' -pid ZOMBIE_PID) in the script ?
On the line after "mpirun ...", assuming that control returns to there after the hang. You didn't answer whether that was the case.
And how to get ZOMBIE_PID from the script ?
Simplest is "pgrep $COMMAND", or use ps.
