I set bash to have unlimited size core files like this: $ ulimit -c unlimited
But, it was not dropping core files for some reason when I was running with mpirun. Just to make sure it would do what I expected, I wrote a little C program that was kind of like this int ptr = 4; fprintf(stderr,"bad! %s\n", (char*)ptr); That would give a segmentation fault. It dropped a core file like you would expect. Am I missing something?

If not, can you increase your coredumpsize to unlimited? This should let you get a corefile; can you send the backtrace from that corefile? > -----Original Message----- > From: users-boun...@open-mpi.org > [mailto:users-boun...@open-mpi.org] On Behalf Of Adams Samuel > D Contr AFRL/HEDR > Sent: Friday, April 07, 2006 11:53 AM > To: 'us...@open-mpi.org' > Subject: [OMPI users] job running question > > We are trying to build a new cluster running OpenMPI.
