Peter Brewer of the SRC makes a good point. I've not tried to say whether loosely coupled distributed networks constitute supercomputers. My favorite example is Manasse's factoring using email of all things. I think its just a matter of time before a few other supercomputer users will resort to things like using gangs of workstations to solve their problem. I know one of our computational fluid dynamicists has Mark's code and has given serious thought to taking spare cycles on our workstations rather than use supers. I think he intends to ask rather than use an improved Morris style flooding algorithm. It's also a matter of time for other disciplines to do this as well. Sure it will be harder than writing convention code, but some users are getting desparate for their fractions of a super. 10% or 1% of a super sounds like a lot of what people are getting everywhere. Imagine battling worms seeking out unused cycles (one could write a novel, maybe make a movie).... But I think for purposes of discussion, supers are confind to "one box" be it a 2 foot high octogon or a aircraft carrier sized build (Cray machine to Smith machine). A different newsgroup can be used for loosely coupled distributed computing. As to 3090s being supers. David just sent me a note: he visited IBM Japan's Tokyo Research Lab. Since 3090's aren't seen as supers, I should just post this to s.c.j. (which most don't read, but I fear the noise ratio might drive some of you away): use the '=' command and just look at headers (if rn, or nn, etc.), I might just forward these things to news groups as needed rather than post to s.c.j., but then I have to think of which group to post...... --e. nobuo miya, NASA Ames Research Center, eugene@orville.nas.nasa.gov {uunet,mailrus,other gateways}!ames!eugene

I offer lunch/dinner to the first to achieve 1/4 TeraFlop. Whether it be the Burton Box, the SuperScary CM-X (Watch that X-factor you CRI stock holders), or maybe Steve Chen.. Wouldn't be great to have a Cray2 whose foreground processor was a front end to the CM-2 fully loaded? Maybe more than one? And wouldn't it be great if the CRI/CM CEs were Kathleen Turner twins? And wouldn't it be great if they\ brought beer and it was TeraFlop beer made in Colorado Springs ??? -- Peter -- Peter Brewer |||| ||||| ||||||||| |||||| //|||||\ |||||| lerici@super.org || ||__ || || || || || THE Supercomputing || || ||^^^^^^\\ || || || Research Center ~~~ |||||||| ||||| || || ||||| \\|||||/ ||||||

As for 3090's being supercomputers...Don't bet on it!! We have a 3090-400 running in our shop, and some recent rumors have us inter- ested in another manufacturer's machine (a plug compatable) that's supposed to be TWICE as fast. An IBM 3090-400 runs about 50 MIPS (That's strictly a guess!!) I won't name names because it's all in the rumor stage right now. Larry Greenwald
