How to run alltoall?

When I replaced ALLREDUCE in microAllReduce.txt with ALLTOALL, the following error was reported. Are there any other places that need to be modified?Thanks！

Start with microAllReduce.txt and reproduce the ALLTOALL run that reaches the assertion in extern/network_backend/ns3-interface/simulation/src/point-to-point/model/rdma-hw.cc at line 251. Trace how the all-to-all collective is configured and identify the additional setup needed so the simulation completes without the NIC assertion.
