描述

I have the same hardware envs, same network, but I could not get the result as you, almost half as you. Any best practices and experience? thanks very much! for bytePS with 1 instance and 8 GPU, I have similar testing result.

研究方向
The issue is a open ended query about reproducing BytePS performance benchmarks. To assist, first clarify the user's exact hardware, software versions, and network topology. Then, review BytePS configuration files and compare with published benchmarks. Check for common pitfalls like NCCL settings, network latency, or GPU affinity. Provide step by step tuning guidance and recommend running a simple allreduce test to isolate the bottleneck.
