Description

When I check the log from 16 H100 to run allreduce, I find flow size = packet size always=16MB, but packet size in rdma cannot be such big. So the packet size info is from SimAI? it is not from NS3?

Research direction

Start with the 16-H100 allreduce run and trace where the logged flow-size and packet-size values are produced in SimAI and NS3. Compare the reported 16 MB value with the RDMA packet-size semantics; done means identifying the source of the packet-size field and documenting or correcting the discrepancy.
