Not yet. I have many benchmarks now but only against GNU Go level _0_ on 9x9 and 13x13. The best WR on 9x9 is 72% using four quad-core PCs on a GbE private LAN with 0.16 second per move (less than 10 seconds per game) but the speed-up (strength-speedup by G. Chaslot) against 1 PC is just 1.6. This may be improved in longer time settings but I'm not sure. # I can use only 4 x 4 cores in hand now so that it's very hard to have benchmarks on 19x19. >In 19x19, it's much better, but the MPI parallelization of 9x9 Go is >challenging. Strongly agree. Even in 13x13, it's much better.
