torch.distributed.init_process_group('nccl',timeout=datetime.timedelta(hours=2.0)) The problem is that when I tried to reproduce this in a minimal example, I couldn't. It's happening inside a big codebase. Hence my original questions: Is it possible that some other library messes up the ...

processgroupnccl是指在分布式训练中,使用NCCL库作为通信后端进行多GPU间的数据同步和集合操作(如广播、归约等)的进程组。NCCL是NVIDIA提供的一个高性能库,专门用于GPU间的通信,特别适用于深度学习中的多GPU并行计算。 解释pg_timeout_参数的作用: pg_timeout_是processgroupnccl进程组中的一个参数,用于设置NCCL操...

🐛 Describe the bug The document about init_process_group https://pytorch.org/docs/stable/distributed.html#torch.distributed.init_process_group suggest timeout has been avaliable in NCCL backend. But I cannot get the following work: impor...
One pain point of debugging the distributed training job with thousands of GPUs is that when NCCL timeout, it's hard to find which ranks are not joining the collective call. Can the timeout rank print this information? Thanks! Collaborator AddyLaddy commented Apr 22, 2024 There is no watc...
