Geraldo,
The previous message you saw was for our Altix ICE system. Since we
started seeing these errors after upgrading to SGI Propack 6, I wonder
if there's a bug somewhere in the Propack software or an incompatibility
between Open MPI and OFED 1.3 (we had no problems under OFED 1.2). A
workaround I stumbled across is to turn off the sm component:
mpirun --mca btl ^sm . . .
That seems to allow our application to run, although I guess at the
expense of losing on-node shared memory support.

Hi to all,
I am using the same subject of a recent message I found in the list
archives of this mailing list:
http://www.open-mpi.org/community/lists/users/2008/10/7025.php
There was no follow-up on that one, but will add this similar report
in case a list member can give us an idea of how to correct it. Or
whose bug this could be.
My application behaves as expected when I run it in a single host and
multiple MPI nodes of our SGI Altix ICE 8200 cluster with in
InfiniBand. When I try the same with multiple hosts, using the PBS
batch system the program terminates with a segmentation fault:

Most of the software infrastructure is provided by the Intel propack.
Any hints of where to look further into this bug?
Thanks in advance.
