MPI
基于c与MPI并行程序初步
第一片儿小代码：
#include "mpi.h"
#include
#include
void main(argc,argv)
int argc;
char *argv[];
{
int myid, numprocs;
int namelen;
char processor_name[MPI_MAX_PROCESSOR_NAME];
MPI_Init(&argc,&argv);
MPI_Comm_rank(MPI_COMM_WORLD,&myid);
MPI_Comm_size(MPI_COMM_WORLD,&numprocs);
MPI_Get_processor_name(processor_name,&namelen);
fprintf(stderr,"Hello World! Process %d of %d on %s\n",
myid, numprocs, processor_name);
MPI_Finalize();
}
