Not offhand. The error you're seeing *typically* indicates that you've got a mismatch of OMPI version somewhere. Are you running on multiple machines with different Open MPI versions, perchance?
If you're running only on a single machine, try completely uninstalling the Open MPI package, re-installing it, recompiling your trivial app, and see what happens. Also, you might want to check the output of "mpicc yourapp.c --showme" and see if it's pointing to the right libraries, etc. On Jul 19, 2013, at 7:06 PM, "Kevin H.
