7. Write a MPI Program to demonstration of Broadcast operation.
COMMAND:
- Create:
gedit prg7.c - Compile:
mpicc prg7.c -o prg7 - Run:
mpirun -np 4 ./prg7
PROGRAM:
#include <mpi.h>
#include <stdio.h>
int main(int argc, char *argv[]) {
int rank, size;
int number;
MPI_Init(&argc, &argv);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Comm_size(MPI_COMM_WORLD, &size);
if (rank == 0) {
number = 50;
printf("Process %d broadcasting number %d to all other processes.\n", rank, number);
}
MPI_Bcast(&number, 1, MPI_INT, 0, MPI_COMM_WORLD);
printf("Process %d received number %d\n", rank, number);
MPI_Finalize();
return 0;
}OUTPUT:
