[AMBER-Developers] Useful scaling efficiency for multi GPU PME?

Hey guys, nvidia now has a multi GPU FFT. It starts showing returns around
a million atoms or so. Hypothetically it could start showing returns sooner
with smaller systems if you ran more than one system at once. But my
question here is what is the level of scaling efficiency that would make
this compelling for say 2, 4, 8, or 16 GPUs?
