Open a897456 opened this issue Sep 22, 2023 · 0 comments OpenMar 23, 2023 · I wanted to use a model I found on github to run inferences. But the problem is in the main file they used distributed training to train on multiple gpus and I have only 1. world_size = torch.distributed.get_world_size () torch.cuda.set_device (args.local_rank) args.world_size = world_size rank = torch.distributed.get_rank () args.rank = rank. Performance at scale. We tested NCCL 2.4 on various large machines, including the Summit [7] supercomputer, up to 24,576 GPUs. As figure 3 shows, latency improves significantly using trees. The difference from ring increases with the scale, with up to 180x improvement at 24k GPUs.
