Cpu becomes a bottleneck for autogtp, is there some issue? #60

Closed nanzi closed 4 years ago

nanzi commented 4 years ago

My recent amd cpu is in full load while gpu usage is only 20%, intel cpu users complains it in the same(They have 16cores recent cpus or so). I have tested as -g2 works fastest on my laptop and -g4 make my cpu crazy while gpu never jumps over 30%. Why cpu becomes a bottleneck?

Hope SAI becomes better, and wish you have a good day!

It should be identical to LZ from this point of view. Generally, on my computer I use -g strictly less the number of cores, though. I agree that -g4 with 4 cores slows the pc considerably

i can run validation -g2 with --sai --sai on i5-6600+8G+GT730-2G win7 ok but though i can run validate -g2 on i7-8700+32G+quadro P620-2G win 10 at first, it always fails after some games
