I've collected some info posted in the distributed perft thread. Using Sharper 0.17p to do perft calculations with hash table has given the following results: <PRE> Hardware Hash CS Nodes MNPS Athlon XP (Barton) at real 2400MHz 256 51254 84998978956 165 P4 3.06Ghz 256 49801 84998978956 170 Athlon XP (Barton) at real 2400MHz 512 45422 84998978956 187 Athlon XP 2.5GHz, 200fsb(400DDR) with 3-4-4-10 512 43848 84998978956 193 Athlon XP (Barton) at real 2400MHz 1024 42027 84998978956 202 </PRE> Single cpu machines counting 202 million nodes per second is really impressive. If you have a machine that you'd like to bench, download the distributed perft client (Sharper 0.17p is included with it). Set the hash size with "hashsize XXX" (XXX = number of megabytes of ram) and run "perfthash 8" and report the time it took to finnish the calculation. I'm going to add some lower spec. machines later. /Regards Albert
