以下是符合标准的 MPI-3 C 程序吗？

#include <mpi.h>
int main(int argc, char** argv)
{
  int dlocalouter=1, dglobalouter=0, dlocalinner=1, dglobalinner=0;
  MPI_Request router, rinner;
  MPI_Init(&argc,&argv);
  MPI_Iallreduce(&dlocalouter,&dglobalouter,1,MPI_INT,MPI_SUM,MPI_COMM_WORLD,&router);
  MPI_Iallreduce(&dlocalinner,&dglobalinner,1,MPI_INT,MPI_SUM,MPI_COMM_WORLD,&rinner);
  MPI_Wait(&rinner,MPI_STATUS_IGNORE);
  MPI_Wait(&router,MPI_STATUS_IGNORE);
  MPI_Finalize();
  return 0;
}
