Even on my slow P850 Ruffian can show more than 512 Kn/seconds Here is some analysis of one of the position of the game by Ruffian. depth=12 1/48(Rh5) +0.96 Rh5 Rc3 Qxc3 Qxh5 g4 Qg5 Qa3 h5 h3 Qh4 Qxd6 Qxh3 Qxa6 hxg4 Qxb5 Nodes: 34277608 NPS: 548266 Time: 00:01:02.52 Why did Ruffian search only 512 knodes per second on 1.8Ghz? Are you sure that Ruffian used 100% of the time of your second processor? Uri
