We'd like to run an experiment and see if MAGMA will run any faster/better/different with a larger page size.
Larger pages will reduce TLB thrashing/pressure. The best way to tell if you need it is to run performance counter tools during your program run. If you haven't, you might be optimizing something which provides minimal if any benefit.
Have you profiled the code (using any of the various tools) to see where it is spending its time?
