Carlos -
Looks to me like the fix data you are looking at for bohr is for 2
processors, whereas the fix data you are looking at for unc/duke is for 1
processor. The performance ratios for pmemd on fix and jac are consistent
with earlier results on the pentium. This is all eyeballing, instead of
ratios. You know that everything here except for GB (and G5 I think) is
pmemd, right? By the way, the "UNC/duke" rubrik is for "benchmarks done
Bob Duke who is at UNC, machine is in his home office". This is probably
more clear for the whole pmemd xeon benchmarks page I wrote up and Dave
added to the web site. I did not see much improvement for hyperthreading
this stuff; Dave Konerding has preliminary results showing a worthwhile
speedup however by the time you have several dual xeons talking over a GB
ethernet. I am waiting for it to be reproduced (and may also get around
doing a 2 dual boxes test myself, one of these days).
Regards - Bob
