Well mostly I look at MPI scalability. I'm not two concerned with Linpack as I am sure it will run well. I like to beat on the NAS suite (no dead horse were harmed in these tests however). > Are the numbers you are reporting from Appro Dual Socket Blades?

Can you clarify without violating an embargo The hardware was two - 2 socket 1U servers, connected with IB (16 cores total) with which I tested the Clovertown last year. So it makes for a good comparison (pop in new processors) I also used a newer kernel (2.6.22) and gcc/gfortran 4.1.2 (last year I used gcc/g77 3.4.5 and kernel 2.6.9) I can't talk about Appro product launches because I don't really know about them. I can say last year I was less than enthused about Clovertown. This year, I think the numbers are well worth looking at. :-) -- Doug > ... ;-) ... > Cheers, > rbw > -- > > "Making predictions is hard, especially about the future." > > Niels Bohr > > -- > > Richard Walsh > Thrashing River Consulting-- > 5605 Alameda St. > Shoreview, MN 55126 > > Phone #: 612-382-4620 > > !DSPAM:4734e79214461735719037! > -- Doug _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
