Question
When running the alltoall test through nccl-tests, specify the use of the Inspector plugin, I obtained some measurement results. But there are two questions I would like to ask:
- Whether the p2p_exec_time_us measured by the NCCL Inspector plugin includes the communication time between GPUs?
- Does p2p_exec_time_us include the latency measurement results between GPUs on different servers?
NCCL Version
v2.30.3+cuda13.0
