I'm on a HPC cluster. So, the openmpi-1.6.4 here installed as a module. In .pbs script, before executing my code-line, I'm loading both "nwchem" and "openmpi" module. It is working very nicely when I work on single node(with 16 processors). But if I try to switch in multiple nodes with "hostfile" option, things are starting to crash.
