Originally, MPI was designed for distributed …Speci cally, the MPI BCAST routine copies data from the memory of the root process to the same memory locations for other processes in the communicator. Clearly, you could accomplish the same thing with multiple calls to a send routine. However, use of MPI BCAST makes the program easier to read (one line replaces loop)to run an MPI program • In general, starting an MPI program is dependent on the implementation of MPI you are using, and might require various scripts, program arguments, and/or environment variables. • mpiexec <args> is part of MPI-2, as a recommendation, but not a requirement, for implementors.Communicators and Ranks.
