Vers: MKL5.0 vs. ATLAS3.2.0 on PII & PPRO
I include below MKL5.0 and ATLAS 3.2.1 timings on PII and PPRO platforms.
There's very little difference between the two, but MKL seems to be
better overall on these architectures.
The most interesting part of the timings for me is in confirmation of my
earlier theory on Level 1 performance. If you recall, I said I thought
MKL beat us badly on Level 1 for the PIII because of two factors: prefetch
and 1-cycle ABS.
PII and PPRO do not have prefetch, and we see that ATLAS now essentially ties
MKL for all the routines except NRM2, ASUM and AMAX, all of which use ABS . . .
Cheers,
Clint
