ThreadNumPerBlock通常取值是256/512/1024(经验而谈,值越大越好)。 但有时预先选好的值达不到100%Occupancy,所以选取可以达到最高Occupancy的最大值。 那么,什么是Occupancy? x.1 Occupancy的定义 a CUDA device's hardware implementation groups adjacent threads within a block into warps. A warp is considere...
Check _is_cuda() before trying to determine number of nvcc threads in compute_num_jobs. This will avoid an error where CUDA_HOME is not defined on machines without CUDA/nvcc installed, e.g. AMD.
There seems to be a bug on Windows 10 with cuda devices. torch.nn.DataParallel(model) will move model parameters and buffers to the GPU even if selfplay_device = 'cpu'. If you move the model to cpu model.to(torch.device('cpu')) after the...
设置为true之后，每一个worker会在loading完数据后继续保持，直到下次被调用，继续loading数据到gpu，中间...
worker数字越多，你在读取数据的占用内存越大，并行的副产品就是内存占用，虽然效率提高。然后因为使用gpu...
首先,你需要查看配置文件或代码中cfg.device_num的设置。这个值应该代表你想要使用的CUDA设备数量。例如,在配置文件中可能会有类似下面的设置: python cfg.device_num = 2 # 假设这里设置为2 确认系统中可用的CUDA设备数量: 接下来,你需要确认你的系统中实际可用的CUDA设备数量。这可以通过torch.cuda.device_count...
I was converting path_aggregation.cu from libSGM.An include file path_aggregation.hpp creates a member cudaStream_t m_streams[MAX_NUM_PATHS];. DPCT converted it to sycl::queue m_streams[MAX_NUM_PATHS]; but this is causing compilation error : path_aggregation.dp.cpp:3...
Within ~15 minutes, test_backward_nan_to_num_cuda_float32 (__main__.TestNestedTensorOpInfoCUDA) will be disabled in PyTorch CI for these platforms: linux. Please verify that your test name looks correct, e.g., test_cuda_assert_async (__main__.TestCuda). To modify the platforms list,...
