[MPICH] Re: collective abort of all ranks

[Kamaraju Kusumanchi]

This is what I did in my previous email. I ran 4 processes on each
node locally and ran the program on each node. In this case the code
executes without any errors on all the nodes. The problem shows up
only when I boot 4 processes across the nodes (one on each node).
