That would be incorrect. bash doesn't read .bashrc on non-interactive login
shells. See the INVOCATION section of the bash manpage.
Personally, I'd make sure the openmpi binaries were built with the correct
rpaths and refuse to LD_LIBRARY_PATH. Then either call mpirun with the full
path or set PATH at the top of the batch script.
