To support Mark's statement, at this page, http://www.spec.org/cgi-bin/osgresults?conf=cpu2006&op=form you can enter '6' in the "# Cores Per Chip " field and hit the "Fetch Results" button at the bottom. You will see 36 results as hits -- I think they are all Dunnington. The more interesting are the "CINT2006 Rates" and "CFP2006 Rates" as you scroll down. I think that some of the Integer Rate results are records or near records for x86_64 compatible machines, at least for 4-CPU (4 socket) machines. I think the FP Rate results are very good, but not quite at the level of some 4-socket, 16-core AMD Barcelona results. Since FP is more relevant for HPC (not that INT is totally irrelevant), this supports Mark's point. -Tom > iirc, the 6-core chips > are also > quite big/expensive. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
