Subject: Re: [OMPI users] Open MPI program cannot complete
From: Jack Bryan (dtustudy68_at_[hidden])

Would like to tell me how to use
(gdb --batch -ex 'bt full' -ex 'info reg' -pid ZOMBIE_PID)
in MPI ?
I need to use #PBS parallel job script to submit a job on MPI cluster.
Where should I put the (gdb --batch -ex 'bt full' -ex 'info reg' -pid ZOMBIE_PID) in the script ?
How to get the ZOMBIE_PID ?
Any help is appreciated.

Thanks, the problem is still there.
This really doesn't prove that there are no outstanding asynchronous requests, but perhaps you know that there are not, despite not being able to post a complete test case here. I suggest attaching a debugger and getting a stack trace from the zombies (gdb --batch -ex 'bt full' -ex 'info reg' -pid ZOMBIE_PID).
