[mpich-discuss] [mpich2-maint] help for running MPICH2 under Window 7

[Jayesh Krishna]

Hi,
 Try the following commands and let us know the output of each command

# Run "which mpiexec" (To make sure that you are using the right mpiexec)
# Run "mpiexec -n 2 c:\Progra~1\MPICH2\examples\cpi.exe"

 Have you compiled "exe\cpi.exe" and "exe\cxxpi.exe" with the latest MPICH2 libraries ?

Regards,
Jayesh

This means the ‘mpiexec.exe’ must be with ‘cpi.exe, cpxx.exe, and fpi.exe’ under the same directory. Otherwise the problem is occurred. 
If I copy ‘mpiexec.exe’ into the directory where cpi.exe is and run mpiexec –n 12 cpi.exe. then the test is successful.

HI, Jayesh, 

Thanks indeed for your reply. 

I did it in terms of your suggestions. But the problem is still there. 

I run tests as follows: 

I entered C:\Program Files\MPICH2\examples
and ran  mpiexec -n 12 cpi.exe
the error prompt is as before: 
"CreateProcess failed, error 2
Unable to start the local smpd manager"

However, if I entered c:\Program Files\MPICH2\bin
and ran mpiexec -n 12 ../examples/cpi.exe
test is successful and cpi.exe works well under 12 CPUs. 

This means I cannot do tests under the directory C:\Program Files\MPICH2\examples where cpi.exe is. 

I look forward to your suggestions again and have a good day.

 Uninstall your existing version of MPICH2 and follow the instructions in Section 9.4 (NOT 9.1) of the installer's guide (http://www.mcs.anl.gov/research/projects/mpich2/documentation/files/mpich2-1.4.1-installguide.pdf).
 Let us know if you still have issues.

Regards,
Jayesh

Hi, Dear Sir or Madam, 



I just installed MPICH2 on my computer of Window 7 and ran the examples cpi.exe. 

When I enter the following command: 



mpiexec –n 4 cpi.exe 



the prompt is as follow: 

“CreateProcess failed, error 2 

Unable to start the local smpd manager.” 



Could you tell me how to solve above problem? I look forward to hearing from you. 

Thank you in advance.
