I put in /etc/bashrc and opened a new shell, but I still am not seeing any core files.

I think if you will add "ulimit -c unlimited" to you default shell configuration file (~/.bashrc in BASH case ant ~/.tcshrc in TCSH/CSH case) you will find your core files :) Regards, Pavel Shamis (Pasha) Adams Samuel D Contr AFRL/HEDR wrote: > 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.
