Hello, I would like to sniff the OMPI network traffic from outside the MPI application.
I was traversing the OpenMPI code and documentation, but I have not found any central point explaining MPI communications from the network point of view. Please, is there any official documentation, or paper, or presentation or picture about MPI packet headers? Sorry if this a basic question or if it was already answered. Thanks in advance for your help! BR, VĂctor.
