Thanks Steve. Yes, that's right. We are probably a small customer for
them. Around 40 servers. So I doubt they will benchmark my application
for me. Do they actually take the effort to compile your scientific
app on several architectures? Just curious. Many of these apps don't
exactly run "out of the box" and it takes some work to get them
running. Or do you use some "standard" easily compiled package as a
benchmark analog?

True; we miss out on all the juicy details from the classified folks.
