[OMPI users] MPI Tool Information Interface (MPI_T), details on collective communication

Hi, I'm currently working on a project that aims to perform detailed measurements of internal MPI communication, particularly based on the PML layer. For example, I would like to measure internal point-to-point communication within collective operations. I’ve seen that using the monitoring

Anna, The monitoring PML tracks all activity on the PML but might choose to only expose that one that the user can be interested in, aka its own messages, and hide the rest of the traffic. This is easy in OMPI because all internal messages are generated using negative tags (which are not allowed f
