ALl,

A tidbit about the K& configuration on that univeristy web site. Not only are the benchmarks mde up, but the numbers are all wrong (I was point to this by a friend of mine).

ftp://ftp.stanford.edu/class/ee382/dp2/k7.mxs

COnfiguration file... contains (read this carefully):

# L1 Cache Size (kBytes)
# PC_LATENCY 1
PC_LATENCY 64
# L1 Hit Latency (cycles)
# PC_CACHE_SIZE 1
PC_CACHE_SIZE 3


A 3K 64 cycle L1 cache.. yeah that's good for performance!

Coppermine is screwed too.. 1K 16cycle latency L1... that right there would explain the performance numbers.. anyway.

Regards,

Steve
