Hello World The sample program uses MPI and has each MPI process print Hello world from process i of n using the rank in MPI COMM WORLD for i and the size of mpi comm world for n you can assume that all processes support output for this example Note the order that the output appears in. Depending on your MPI implementation, characters from different lines may be intermixed. A subsequent exercise(7O master/slaves)will show how to order the output You may want to use these mpi routines in your solution MPI Init. MPI Comm size.
