Resolution to this. Upgrading to OpenMPI 1.6.2 and getting Intel
Cluster Studio 2013 did the trick.

Interesting. I figured that might be the case. I will have to contact
Intel and find out if we can get a newer version.
Thanks.

Did this ever get a followup? If not...
We've seen problems with specific versions of the Intel compiler that
randomly set fault in strange places. The only solution was the
upgrade the Intel compiler to the latest version in that series.

I'm trying to build OpenMPI 1.6.1 with Intel Cluster Studio 2012 for
use on our cluster however I'm running into a bit of a problem. The
OpenMPI itself builds fine as does the code I'm testing with.
However when I try to run on more than about 16 processors the run
seg faults and when I turn on traceback it seems to point to this call:
CALL MPI_INIT_THREAD(MPI_THREAD_FUNNELED, provided, ierr)
This is a pretty standard call. Even stranger when I use a different
version of the Intel Compiler 12.0.3 20110309 it doesn't have any
problems.
The version of the Intel compiler in Intel Cluster Studio 2012 is
12.1.0 20110811.
Does any one have any thoughts about this error? I've tried turning
off any optimization to no avail. I even tried turned on debug mode
for OpenMPI but I can't get any thing more specific as to why it is
failing. I even tried compiling Intel MPI Benchmark, which failed
in a similar way, which indicates that its a problem specifically
with the interaction of MPI and the intel compiler and not the code
I was working with.
Thanks.
