[MPICH] core dumps MPICH & Linux

[Wolfram Brenig]

I'm trying to force core dumps on
a heterogeneous linux cluster running
mpich2version: 1.0.2 and SuSE linux
versions 9.2 and 10.0.

I have set "ulimit -c unlimited" on all
nodes.

When I run non-parallel code I can get
core dumps. But no parallel program will
core dump.

Any help, or hint where to get info
would be most appreciated.

>From searching the WWW I got the
impression that linux may not be able
to do core dumps with MPI. Is this so?
