MPICH是MPI的重要研究,提供了一系列的接口函数,为并行计算的实现提供了编程环境.

#include "mpi.h"

#include <iostream.h>

int main( int argc, char *argv[] )
{
  MPI::Init( argc, argv );
  cout << "size= " << MPI::COMM_WORLD.Get_size() << "\n";
  cout << "myrank = " << MPI::COMM_WORLD.Get_rank() << "\n";
  MPI::Finalize();
  return 0;
