MPI find minimum demo

How to find the 'find minimum' using MPI.

#include "mpi.h"
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#define MAXSIZE 1000
void main(int argc, char **argv) {
  int myid, numprocs, data[MAXSIZE], i, x, myresult, result, status;
  FILE *fp;
  MPI_Init(&argc,&argv);
  MPI_Comm_size(MPI_COMM_WORLD,&numprocs);
  MPI_Comm_rank(MPI_COMM_WORLD,&myid);
  if(myid == 0){ 
    if((fp = fopen("./rand_data.txt", "r")) == NULL){
      printf("Can't open the input file\n");
      exit(0);
    }
    for(i = 0; i < MAXSIZE; i++)
      status=fscanf(fp,"%d", &data[i]);
  }
  MPI_Bcast(data, MAXSIZE, MPI_INT, 0, MPI_COMM_WORLD); /* broadcast data */
  myresult=data[myid];
  printf("Rank %d had: %d\n", myid, myresult); 
  MPI_Reduce(&myresult, &result, 1, MPI_INT, MPI_MIN, 0, MPI_COMM_WORLD);
  if(myid == 0){
    printf("The minimum is %d.\n", result);
  }
  MPI_Finalize();
}

Fill ./rand_data.txt with 1000 random integers.
