Athlon 1.2Ghz results == P4 1.5

[R Clint Whaley <rwhaley@cs.utk.edu>]

Guys,

I include below the new stuff on a 1.2Ghz Athlon with DDR memory.  This is
Julian's kernel, with Peters mods, plus the new cacheedge, and we are talking
over 80% of peak in out-of-cache performance on a 1.2Ghz machine.  If
you compare these numbers in double precision (real and complex), you will
find that the Athlon wins big for small-medium size probs, and ties for large
with a 1.5Ghz P4.  It gets very close to the performance of a 800Mhz IA64
as well.  I am impressed.  Of course, the P4 cleans up the place in single,
since it is using SSE for double the theoretical peak . . .

You'll notice that the double complex performance is much better than the
last time I posted numbers; it was a problem with cacheedge setting screwing
it up before . . .

Cheers,
Clint
