I'm working on some intercommunicator stuff at the moment. According to
"An inter-communication is a point-to-point communication between
processes in different groups" [Section 6.6]
yet the "man" page for MPI_Comm_size reads:
"If the communicator is an **intra-communicator** (enables
communication between two groups), this function returns the size of
the local group"
Shouldn't that be **inter-communicator**?
