QuestionIs there a way to trace an mpi message through a topology? Pin

Hello, first of all I have to apologise if my question is stupid or asked in the wrong place.

I'm rather new to mpi and i just discovered how to achiave a topology aware communicator, using mpi_graph_create. The thing that I cannot seem to achieve is to track messages through said topology.

For example if I call MPI_Send/MPI_Recv is 2 "non-adjacent" processes, is there a way to check the route that message takes through the graph?
