I'm using the cluster of the university where I work und I'm not the
admin. So I'm going with what is installed there.

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".
 

It's the first time I'm using MPI. Before I complain to the admins about
old versions or anything else, I'd like to check whether my code
actually should be okay in regard to MPI specifications.
