NUMA (each cpu has 1/2 of memory as local) or SMP (memory is interleaved across CPUS 1 page at a time)?? I _may_ have a quad opteron to use for CCT myself. AMD is trying to ship one to me for evaluation, and they are trying to get it here prior to the tournament, whether it will make it or not is unknown. I'd like to have it here long enough that I can work on the kernel a bit to get the NUMA support up and going. My previous opteron numbers had some NUMA changes, but the O/S didn't support the NUMA library so there was some more performance to be had, if I can find time to get Linux on the right page with me... Don't forget, "long" on a gcc made for opteron is 64 bits. "int" is 32. %ld vs %d can be a headache. > There are a few 64 bit bugs I have to work out, but here is a preview of CCT6: > >The position is Topalov-Bareev from one of the rapid playoffs.
