Have you tried just adding -x LD_LIBRARY_PATH to your mpirun cmd line?
This will pickup your local LD_LIBRARY_PATH value and propagate it for
you to the remote node.

Hey,
I suspect that my not changing my .bash_profile is indeed the
problem unfortunately I do not know were yum placed open's lib and
bin directories. I tried looking in /usr/local/ but did not find and
openmpi directory, I suspect this has something to my Fedora
distribution as apposed to the Debian bellow. Could anybody tell me
where I could suspect to find the directory to place in my profile
on a Fedora or Red hat system when installed through yum? Much
appreciated.

I had a same problem like this.
I am using Debian on my nodes, the problem was with non-interactive
shell invocations,
I added "export LD_LIBRARY_PATH=/usr/local/openMPI/lib" at the top
of the ~/.bashrc files in all nodes then it worked.
Regards.

Hey,
Please help me out as I cannot figure out from all the
online documentation why my cluster wont work.
1) I started with two computers with a fresh install of Fedora 10.
2) Created two user accounts on the two computers with the same
user name.
3) Created an rsa keyed ssh between the two computers going both
directions, so that each computer can log into one another without
being prompted for a password.
4) Installed openmpi on both via yum with the command "yum install
openmpi openmpi-devel openmpi-libs".
5) Compiled and ran hello.c with a host file containing the IP
addresses of both computers with slot numbers. But openmpi only
hangs for minutes, until I kill it.
I am able to run hello.c locally and even with a hostfile
containing only the local machines address, but am not able to
started a multi node program from either computer. Have I done all
the correct steps, am I missing something?
