windows下MPICH2安装

###下载 下载地址

###安装

1. Install MPICH2 version 1.4.1p1 on your machine using the installer downloaded from the downloads page http://www.mpich.org/downloads. Be aware to choose either a 32-bit version or 64-bit one depending on your machine.
2. During installation select MPICH2 to be installed for Everyone.
3. Also make sure that you keep the default setting for passphrase (usually behappy) during the installation.
4. After installing MPICH2 successfully, you may add rules to your firewall to allow the programs mpiexec.exe and smpd.exe to communicate through firewall. This process depends on your firewall.
5. You need to add the bin folder of MPICH2 (usually C: \PROGRAM FILES \MPICH2 \bin) to your PATH. Next, open an admin command prompt by right-clicking on the command prompt icon and selecting run as administrator.

###后续工做 In the command prompt type the following commands in sequence: smpd -install mpiexec -remove mpiexec -register mpiexec -validate (it should return SUCCESS) smpd -status (it should return 'smpd running on <hostname>') If the last two commands are successfully，then go to next step.

###试运行### find a example under /MPICH2/examples just like "mpiexec -n 2 mpi.exe" perfect !!!

###注意点### the username and password are users' of your computer, not admin or other invalidate account.
