marketing pop-ups here:
http://intel.com/business/bss/products/server/xeon/index.htm?iid=ipp_srvr_pr
oc_xeon+xeon_srvr&
they state that the 4 MB 3.2 GHz Xeon MPs are 3 times
as fast as the 700 MHz 1 MB cache model.
I have one more day to benchmark on a dual Opteron
system before the eval system goes back. HP offers no
64 bit support for their integrated RAID controllers.
"Oh, if you want to run 64 bit, buy an Itanium
system".
Still run by them marketing types.
makes me wanna buy a Sun Opteron-based server.
post your code, and I'll run it tomorrow.
