I find that meep is more faster (3-4 times faster, maybe) on the first nodes than all other nodes. I've tried other programs on this cluster and find no such problems. All nodes are running at a similar speed.
My first guess is that you are running a problem that is saving a lot of files, so that you are I/O bound, and the I/O from the first node is faster. Try running a simulation that doesn't output any HDF5 files.
