[torqueusers] p4_error: interrupt SIGx: 15

Hi Samir, list

This is not likely to be a Torque problem,
but generated by the old MPICH-1 and how it works/doesn't work
with newer kernels.

The easy fix is to upgrade to MPICH2
with the Nemesis communication channel,
or to OpenMPI.
There was a long discussion about p4 errors from
MPICH 1.2.7p1 in Rocks 5.1 not so long ago.
Follow this thread backwards to see the details:


I hope this helps,
Gus Correa
