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

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.
