Web06. maj 2024. · @ezyang I'm not sure the title is correct though - all programs do not run singlethreaded by default, they just use default OMP/MKL settings.. You can see in init_num_threads that what it does is: omp_set_num_threads(mkl_get_max_threads()); Supposedly that results in better perf.

WebDepending on the PyTorch version you use, maybe this function will not work correctly. See why in this issue. In there, you'll see that if needed you can use environment variables to limit OpenMP or MKL threads usage via OMP_NUM_THREADS=? and MKL_NUM_THREADS=? respectively, where ? is the number of threads. Web06. jul 2024. · In this post, I will share how PyTorch set the number of the threads to use for its operations. torch.set_num_threads() is used to set the number of threads used for intra operations on CPU. According to discussions here, intra operation roughly means operations executed within an operation, for example, for matrix multiplication.By default, … Web19. nov 2024. · The fine-tuning times were: Single-node: 11 hours 22 minutes, 2 nodes: 6 hours and 38 minutes (1.71x), 4 nodes: 3 hours and 51 minutes (2.95x). It looks like the speedup is pretty consistent. Feel free to keep experimenting with different learning rates, batch sizes and oneCCL settings. pre ongard well operator
