[Jayesh Krishna]

Hi,
 Can you try executing the following command ?

     C:\Progra~1\MPICH2\bin\mpiexec -n 2 hostname

 Also try running,

     C:\Progra~1\MPICH2\bin\mpiexec -n 2 c:\Progra~1\MPICH2\examples\cpi.exe

 Let us know the results.

Regards,
Jayesh

Hi, 


Thank you for your reply! Well actually I added the path to mpiexec in Control Panel, and it doesn't work. Windows still cannot recognize mpiexec.exe. I am wondering if there are any dependencies to install and run MPICH2? Thanks! 


Regards

Hi, 
It looks like you haven't added path to mpiexec (c:\Program Files\MPICH2\bin) to your PATH (Control Panel --> System --> Advanced --> Environment Variables). Or you can specify the complete path to mpiexec (C:\Program Files\MPICH2\bin\mpiexec -n 2 hostname). 

Regards, 
Jayesh

Hi there, 

I recently installed MPICH2 for windows 64bit machine, and I tried to compile the "mcstas" program which uses some language based on C, with mpi, running on multiple cores of the machine, but the compilation failed, and it showed this error: 

'mpiexec.exe' is not recognized as an internal or external command, 
operable program or batch file. 
Press any key to continue . . . 

Is it because MPCH2 is not installed properly on the machine? Or I need to set some environment variables? I could not figure out how to deal with this. So many thanks! 

Ruizi
