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

Mpirun opens separate shell on each machine/node, so the "ulimit" will
not be available in new sheel. 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 :)
