Not really much point since the tournament starts in a few days. For those not noticing, looks like the 4 x 875 opteron system is good to go. Been testing last two nights on ICC and the parallel search is doing quite well on the NUMA architecture, after a bit of modifying the source, and a bit of tuning the crafty internal SMP parameters (splitting depth, max processors at any single split point, etc.). I'm working on getting the last bit of scaling done so that the 8CPU nps will be 8.0x the 1 cpu nps. rather than the current 7.5X. I think I can finish this today... Whether we will play well or not is anybody's guess. But I can guaran-damn-tee you we will be playing _fast_. :)
