并行计算MPICH在windowsXP下机群搭建的问题。

[biaosonya]

我在我们宿舍四台电脑上都装了MPICH，想搭建一个并行计算的机群环境，都是windowsXP操作系统，并且都是登陆用户名都是默认的Administrator，密码我也设置的一样。但是我在用MPICH Configuration 配置的时候，只显示我自己的电脑安装了MPICH，也就是我只有我自己的电脑能应用的到计算环境，别的三台电脑都不能选择，在我的截图上可以看到问题算在。请各位大侠帮帮忙！

You can download an installer from http://www.mcs.anl.gov/research/projects/mpich2/. The installer requires Administrative rights to install the smpd service. This will install MPICH2 to C:\Program Files\MPICH2. You must install mpich on all nodes (computers of the cluster). The mpich2 dll(s) are copied to the Windows\system32 directory. The bin directory contains smpd.exe which is the MPICH2 process manager used to launch MPI programs. mpiexec.exe, also found in the bin directory, is used to start MPICH2 jobs.

See the README.winbin.rtf for details and hints like minimal installation for nodes.

See here about authentification: mpich2-doc-windev.pdf

The best way is to put all nodes into a domain and use SSPI.

For simple testing mpi under windows, you can use the Start \ Programs \ MPICH2 \ wmpiregister.exe and save username and password:

C:\Program Files\MPICH2\bin\wmpiregister.exe

There you must give a valid windows user name and password.

Then open a console and run:

C:\Program Files\MPICH2\bin\mpiexec.exe -n 10 C:\Program Files\MPICH2\examples\cpi.exe

我也碰到了Windows下的mpi测试问题，测试时显示：aborting：unable to connect penghost，smpd verision mismatch，penghost 是我的主机名，请问如何解决啊。。。。

后来我找到了答案，关闭各个机器的防火墙就OK了
