[mpich-discuss] mpiexec on 2 windows computer

Wed Jun 27 12:31:03 CDT 2012

 Make sure that you compile the code on a machine that has the *correct* version (same as the nodes where you run your job) of MPICH2 installed.
 I would recommend resolving the MinGW/VS_2010 issues on your machine and recompiling your code.

(PS: Mismatch of env can lead to a lot of errors and it would be difficult to debug it over emails.)
Regards,
Jayesh

I guess because the first time I try to run cpi.exe in path
C:\Program Files\MPICH2\examples> mpiexec -n 2 cpi
Hehe :)
I'm sorry before.

Honestly, I didn't recompile it, because the code was compiling at
MinGW first (compiling the code in my friend's computer). While, I
have Visual Studio 2010. I try compile using VS2010, but error. And I
have some problem when trying to install MinGW in my computer, it
can't installed well.

Thanks

>>> Hi,
>>>  It looks like you have multiple versions of MPICH2 installed in your system. We do not recommend users to install multiple versions of MPICH2 (You need to uninstall the previous version and install the new version).
>>>  Try specifying the complete path to mpiexec when you run your job (C:\Program Files\MPICH2\bin\mpiexec -n 2 "C:\Program Files\MPICH2\examples\cpi").
>>>  Also check the status of smpd, the process manager, by using the full path (c:\Program Files\MPICH2\bin\smpd -status).
