There's probably some multithreading capabilities of Deep Junior that is hurt significantly by using a single cpu. Are you going to buy a dual machine to unleash that monster? >Example: >r4rk1/p1nqbppp/1pn1p3/P1PpP3/8/BPPQ1N2/3N1PPP/R3R2K b - - 0 1 > >First Deep Junior. >DEEP JUNIOR 6 - Huebner,R > >Analysis by Deep Junior 6.0: >20...bxc5 21.Ne4 Rfb8 22.Nfg5 g6 23.Bxc5 Bxg5 24.Nxg5 Rxb3 > ² (0.39) depth: 16 00:07:22 107973kN > >Then Junior 6a. >Analysis by Junior 6.1: > >20...bxc5 21.Ne4 Rfb8 22.Nxc5 Bxc5 23.Bxc5 Rxb3 24.Qc2 Rb5 25.Bd6 Rxa5 26.Ng5 g6 >27.Rxa5 Nxa5 > ² (0.27) Depth: 16 00:06:42 106120kN > >(Bird, Scarb 08.07.2000) Deep Junior averages about 244Knps vs. 264Knps for Junior 6.0 judging from your data, but the result is clearly different, so the difference must be larger that the actual nps gap. Thank you for the interesting data. Best wishes... Mogens
