I run no opening book versions of MoGo_big with one and two threads on a quad core box, Intel Q6600 at 3GHz, on which mogo_big_1core is running, namely mogo_big_1c_nb and mogo_big_2c_nb on cgos 9x9.
They show good scalability now, though the number of games is not enough yet. One strange thing is that mogo_big_2c seems not weaker than mogo-big-4core. http://cgos.boardspace.net/9x9/standings.html -Hideki Hideki Kato: <[EMAIL PROTECTED]>: >David, I just remembered that the scalability test was done without >any opening book! > >This could be the reason of their different scalablities. > >-Hideki > >David Fotland: <[EMAIL PROTECTED]>: >>The scalability study showed that mogo gains almost 100 rating points per >>doubling of performance. >> >>But on CGOS, there is mogo 1 CPU and mogo 4 CPU.
