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:

  1. Whether the p2p_exec_time_us measured by the NCCL Inspector plugin includes the communication time between GPUs?
  2. Does p2p_exec_time_us include the latency measurement results between GPUs on different servers?

NCCL Version

v2.30.3+cuda13.0
