MPI run crashes on more than one node

Hi everyone,

I'm using MPICH2 v1.5 to run my WRF model on INTEL Xeon Processors. I can run on one node with as many cores as I want but if it exceeds the number of porcessors in a core it will crash with following error:

*********************************************************************************************************************************************

and this is how I run the model:

$ulimit -s unlimited

$source ~/setup-intel.sh

$mpiexec -np nproc ./wrf.exe >& benchmark#n.log

I would appreciate any help in this regard.

Bests,

Arash
