一、简介
通过安装MPICH构建MPI编程环境，从而进行并行程序的开发。MPICH是MPI（Message-Passing Interface）的一个应用实现，支持最新的MPI-2接口标准，是用于并行运算的工具。
二、安装配置
三、程序示例
//hello.c #include "mpi.h" #include <stdio.h> #include <math.h> int main (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 (); return 0; }
编译
mpicc -o hello hello.c
运行
Hello World! Process 1 of 4 on jack-laptop Hello World! Process 3 of 4 on jack-laptop Hello World! Process 2 of 4 on jack-laptop Hello World! Process 0 of 4 on jack-laptop
