My bad - I almost said "Seymour Cray", and should have, as I was talking about the person, not the company. The company merged with (or was bought by) SGI in 1996. SGI also bought MIPS, which might explain the companies predilictions for SGI processors since. Seymour Cray didn't do much with the MP machines. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
