[Rd] Rmpi on CentOS (64bit)

There are many different versions of OpenMPI about.  It looks like you
have one that is set up for specialized hardware.  Either this is the
wrong version or a configuration error, and you will need to talk to
your 'local System Administrator'.

Incidentally, you should not have to set LD_LIBRARY_PATH, but I
frequently have had to add configuration files in /etc/ld.so.conf.d,
including for openmpi on Fedora 12. On Fedora 10 (but not 12) MPI was
under the /etc/alternatives mechanism, and had other problems.  I
currently have

gannet% cat /etc/ld.so.conf.d/openmpi-x86_64.conf
/usr/lib64/openmpi/lib

on F12.
