I have a simple question for you... But who is the best between the intercommunicator and intracommunicator?
Is better use an intercommunicator with Send/Recv or Bcast... or is better use the MPI_Intercomm_merge and to use the Send/Recv or Bcast inside the new intracommunicator created? I talk about the performance...is more faster the inter or the intracommunicator? Do they have the same performance?The same speed? Bye Alfonso
