[OMPI users] segfault with HPL/OMPI/LAM

[Brock Palen]

In trying to test a new large memory machine i have encountered a  
problem with with segfaults.

I am trying to run a large problemsize HPL job.  Once each process  
exceeds ~2GB per process i get segfaults.  This happens with both  
openmpi-1.1 openmpi-1.1.1 and lam-7.1.2  the blas lib is ACML-3.1.0   
and the compiler is PGI-6.1

Is this a known problem with HPL?  each process was never ment to get  
into greater than 2 GB ?
