WebAug 15, 2024 · Pytorch shared memory is a type of memory that can be used by multiple processes at the same time. It is useful for data sharing between processes, especially if those processes are running on different machines. To use pytorch shared memory, you first need to create a shared memory object. Webtorch.Tensor.is_shared — PyTorch 2.0 documentation torch.Tensor.is_shared Tensor.is_shared()[source] Checks if tensor is in shared memory. This is always True for CUDA tensors.

WebJan 17, 2024 · While trying to spawn another process on Linux, if multiple tensors share the same file descriptor (with the shared-memory approach), the PyTorch multiprocessing module calls DupFd on the same FD multiple times: pytorch/torch/multiprocessing/reductions.py Line 322 in fcf8b71 df = multiprocessing. … WebMar 28, 2024 · Moreover, it is not true that pytorch only reserves as much GPU memory as it needs. Pytorch keeps GPU memory that is not used anymore (e.g. by a tensor variable going out of scope) around for future allocations, instead of releasing it to the OS.

WebPlease note that PyTorch uses shared memory to share data between processes, so if torch multiprocessing is used (e.g. for multithreaded data loaders) the default shared memory segment size that container runs with is not enough, and you should increase shared memory size either with --ipc=host or --shm-size
