Is there a way to trace an mpi message through a topology? Cioroiu Adrian-Nicu19-Jan-13 6:39 Cioroiu Adrian-Nicu 19-Jan-13 6:39  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?
