DS-10/20 stream results

[Bill Broadley <bill math ucdavis edu>]

Not sure if this was ever settled on this list, just browsed the previous
few hundred messages, but I noticed:

http://www.cs.virginia.edu/stream/standard/Bandwidth.html
-----------------------------------------------------------------
Machine ID                ncpus    COPY    SCALE      ADD    TRIAD
------------------------------------------------------------------
Compaq_AlphaServer_DS10      1    881.1    929.9    839.9    900.9
Compaq_AlphaServer_DS20      1   1077.0   1244.0   1179.0   1323.0
Compaq_AlphaServer_ES40      1   1004.6   1193.9   1058.6   1237.1

Seems like the DS10 doesn't have quite the memory bandwidth of the
DS-10, but not nearly as low as I feared.

I expect for most codes the difference will be even less since few things
hit the memory system as hard as stream does.  The more cache hits the 
closer the DS10 will be be to 466/500's of the DS20's performance.

I was originally fearing more like 1/2 the DS20's performance which is
a bit closer to pc performance then I'd like considering the price point.

BTW noticed fully configured DP264 prices dropping a good bit, check out
your favorite vendor.
