I tried to config KataGo so it uses both of my GTX GPUs but even reading through the config file and doing my best to set it as instructed it keeps stubbornly only using one for pondering in Lizzie. Could anybody maybe show me how it is supposed to look? Thanks |

Set numNNServerThreadsPerModel = 2 ("I want 2 GPU threads") Set cudaGpuToUseThread0 = 0 ("Thread 0 should use GPU 0") Set cudaGpuToUseThread1 = 1 ("Thread 1 should use GPU 1") Or do the analogous thing for OpenCL if you're using OpenCL. |
