<div>Also, the same script runs fine as well when I use OpenMPI instead of MPICH2. That's why I suspect it is MPICH2 & SGE integration issue.</div><div><br></div><div>The problem is that I need multi-thread support, and it is by default disabled in OpenMPI. I also prefer to use MPICH2 instead of OpenMPI.</div>
<div><br></div><div>I was able to reproduce the problem when I restarted the cluster from scratch. Would any of you please take a look on the problem by trying the same image with MPICH2 plugin?</div><div><br></div><div>
