WebNov 3, 2024 · @ssnl, @apaszke. It looks like in the context-manager in torch/cuda/__init__.py, the prev_idx gets reset in __enter__ to the default device index (which is the first visible GPU), and then it gets set to that upon __exit__ instead of to -1. So the context first gets created on the specified GPU (i.e. GPU5), then some more context … WebMay 2, 2024 · Stage 1: Shards optimizer states across data parallel workers/GPUs.

WebMar 4, 2024 · Compute unified device architecture (CUDA) is a parallel computing platform for the NVIDIA’s GPU, which contains instruction set architecture (ISA) and a parallel computation engine. By using the CUDA technique, the stream processors can be mapped to thread processors to deal with the computation of large-scale dense data. WebJul 6, 2024 · Interestingly, sometimes I get Out of Memory exception for CUDA when I run it without using DDP. I understand that spawn.py terminates all the processes if any of the available processes exist with status code > 1 , but I can't seem to figure out yet how to avoid this issue.

WebNov 14, 2024 · I am having the same imbalance issue but the problem is that my gpu 1 not gpu 0 is going out of memory. Both gpus have 32GB of memory. With NVIDIA-SMI i see that gpu 0 is only using 6GB of memory whereas, gpu 1 goes to 32. I could have understood if it was other way around with gpu 0 going out of memory but this is weird.
WebFeb 5, 2024 · Sorted by: 1. The GPU itself has many threads. When performing an array/tensor operation, it uses each thread on one or more cells of the array. This is why it seems that an op that can fully utilize the GPU should scale efficiently without multiple processes -- a single GPU kernel is already massively parallelized.
