Quadrics/Myrinet/Infinipath folks... care to comment? Somehow I don't
really think that this makes sense, cutting off a $4B+ market growing at
60+%/year in order to service a market of questionable size, growth
rate, and interest, not to mention longevity, but stranger things have

??? I have heard VS called many things. Fast is not one of them.

Er.... uh.... maybe those folks who want the performance that a
distributed memory application can provide? Hey I like OpenMP, I think
the programming paradigm is great. It is hard to get good performance on
shared memory above certain sizes of CPU. Your code starts looking a
great deal more like an explicitly parallel code (MPI) than a shared

Curiously enough, software I wrote/compiled using QuickBasic 4.5 in 1988
still runs on my XP laptops. No rebuild. There werent many DOS/windows
