>(i'd like to make sure you are not using IntelMPI libmpi.so.1 with Open MPI libmpi_mpifh.so.2, that can happen if Intel MPI >appears first in your LD_LIBRARY_PATH)

Before removing /opt/openmpi, I would like to unset the LD_LIBRARY_PATH first to see if it has any effect. Do you agree with that? Regards, Mahmood
