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 
happened.

???  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 
memory code.

Hmmmm.  I rarely bet, but I would bet against this.

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 
versions of fortran available back then that a grad student could afford.
