I have used meep-mpi a few times, and mostly because the problem would not fit the memory of a single computer. I tried to understand how it would scale in terms of CPU without much success. One thing you should do is figure out how much RAM the problems you want to solve require, and ensure the cluster total memory is at least this much. The cluster I used consists of some 21 dual opterons with 4GB RAM per machine, and gigabit ethernet. Maybe someone with more experience than me will be able to clarify this further.
