Hello there,

I have some trouble to have mpi4py works fine, maybe you could help me with it.

I installed MPICH2, it works fine (I can launch command such as "mpiexec -n 4 hostname" and I can launch program in C)

I installed mpi4py, everything seems to works fine but when I launch the hello world in demo I have some trouble:

Command typed:

mpiexec -n 4 demo\helloworld.py

Results:

launch failed: CreateProcess(helloworld.py) on 'Adlen-PC' failed, error 193 - (null)

When I launch simply the helloworld.py it seems to works fine, I mean python doesn't complain about unknown command

I get the expected result:

Hello, World! I am process 0 of 1 on Adlen-PC.

I search on the internet people with this issue but can't find anyone with the same issue.

If you have any idea on it I would be glad to hear it.

Thanks for your help!

Adlen

On windows, I think you really need to run python.exe under mpiexec
control, like this:

mpiexec -n 4 c:\Python27\python.exe demo\helloworld.py
