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
