Provided your account is available over all the nodes of the cluster
(commonly through a shared filesystem (e.g. NFS)),
you can easily install and use a more recent version of OpenMPI.
mkdir -p ${HOME}/ompi-1.5.3 && ./configure --prefix=${HOME}/ompi-1.5.3
make
make install
You should not forget to modify your "PATH" and "LD_LIBRARY_PATH"
environment variables in your ".bash_profile".
