Hmmm but can you do anything with a 3090 host that you can't with a sun?

If adding a paltry 32 T800's to a 3090 provides a massive amount of extra
perfomance on a multi million quid machine what does it say for the IBM?
If the extra performance is negilgable why bother?

Could someone who knows these things please reveal :-

1 the cost of a 3090
2 the performance of a 3090

I seem to recall a sum of arround 4 million quid being the sort of ballpark
figure for the first (but I could be wrong) Maybe they knock 'em out for less
these days.

Some vicious person suggested 24Mips as a figure for the second (but he
happened to be trying to sell a 50ish Mip SUN 2 so I'm not sure whether he's
right.)

I seem to remember a comment made just after the purchase of the Southampton
3090 to the effect that the only use for the thing would be as an upmarket
server for transputers. It is nice to see that the computing service has
finaly agreed.
