"Hello World"
1.Write a program that uses MPI and has each MPI process print the following:
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 may want to use these MPI routines in your solution:
2. Correct the following parallel code
#include < stdio.h > int main( argc, argv ) int argc; char **argv; { int rank, size; MPI_Init( &argc, &argv ); MPI_Comm_size( MPI_COMM_WORLD, &size ); MPI_Comm_rank( MPI_COMM_WORLD, &rank ); printf( "Hello world from process %d of %d ", rank, size ); MPI_Finalize(); return 0; }
