I don't understand the question. Do you have a binary that works on your new cluster or not? I just don't see how recompiling the code fits with the rest of the question. If you have an OpenMPI-linked binary for your FEA, simply copy it out to your nodes, then run it. There are many ways to do this: which is best depends on many factors. Probably scp is your friend if you don't have a common filesystem.
