Microsoft MPI无法运行 [英] Microsoft MPI doesn't run

问题描述

我正在尝试Microsoft的MPI实现.我从这里安装了CCP sdk:

I'm trying out Microsoft's implementation of MPI. I installed the CCP sdk from here:

http://www.microsoft.com/zh-CN -us/download/details.aspx?id = 239

然后在我的项目设置中，添加了include文件夹，lib文件夹并提到了msmpi.lib.

And then in my project settings I added the include folder, the lib folder and mentioned msmpi.lib.

其余设置保持不变，我构建了程序，然后在命令提示符下继续运行该程序，但是启动它后没有任何反应.

With the remaining settings as-is, I build the program and then in the command prompt I proceed to run the program, but nothing happens after I start it up.

这是代码(应该显示每个线程的ID号):

Here's the code (It's supposed to display the id numbers for each thread):

#include "stdafx.h"
#include "mpi.h"
#include <stdio.h>

//Commands in cmd prompt
//cd "C:\Program Files\Microsoft Compute Cluster Pack\Bin"
//mpiexec.exe -n 2 "C:\Users\MyNameHere\Documents\Visual Studio 2012\Projects\tspMpi\Debug\tspMpi.exe"

int main(int argc, char* argv[]) 
{
 int  nTasks = 0, rank = 0; 

 MPI_Init(&argc,&argv); 
 MPI_Comm_size(MPI_COMM_WORLD,&nTasks);
 MPI_Comm_rank(MPI_COMM_WORLD,&rank);

 printf ("Number of threads = %d, My rank = %d\n", nTasks, rank);


  return 0;
 MPI_Finalize();
}

一旦我运行mpiexec.exe(命令在注释中)，该程序什么也不做，直到我按Ctrl-C为止.有人知道我在做什么错吗?生成程序时没有错误，而且如果我从Visual Studio中运行它，就好像只有一个进程在启动一样.

As soon as I run mpiexec.exe (the commands are in the comments) the program just does nothing, until I press Ctrl-C. Does anyone know what I'm doing wrong? There are no errors when I build the program, and if I run it from visual studio, it acts as if there was only one process started up.

推荐答案

我根本没有发现SDK有用，这是我在VS 2010(VC10)中启用MPI群集调试的步骤:

I didn't find SDK useful at all, here are my steps to enable MPI cluster debugging in VS 2010 (VC10):

步骤1.安装MS-MPI: http://www.microsoft.com/en-us/download/details.aspx?id=36045 (仅x64)，这会创建

step 1. Install MS-MPI: http://www.microsoft.com/en-us/download/details.aspx?id=36045 (x64 only), this creates

C:\Program Files\Microsoft HPC Pack 2012\Inc
C:\Program Files\Microsoft HPC Pack 2012\Lib\amd64
C:\Program Files\Microsoft HPC Pack 2012\Lib\i386

第2步.下载示例: http ://msdn.microsoft.com/zh-cn/library/ee441265(v = vs.100).aspx#BKMK_debugMany

第3步.调试设置:右键单击启动项目">属性">调试"

step 3. Debugging setting: Right click on the Startup Project > Properties > Debugging

Debugger to launch, change "Local Windows Debugger" to "MPI Cluster Debugger"
Run Environment, change "localhost/1" to "localhost/4"

右键单击Visudal Studio工具栏区域以检查调试位置"，现在您可以在调试位置"工具栏中切换进程"及其线程"，玩得开心！

Right click on Visudal Studio Toolbar area to check "Debug Location", now you can switch Process and its Threads in the Debug Location toolbar, have fun!
