Subject: Re: [OMPI users] mpirun with WMI on Windows 7

Hi Charles,

I've downloaded a fresh Open MPI 1.4.1 tarball, and built a clean
installer. After installing it onto two machines, everything worked for
me, I tested to launch notedpad and also other simple MPI applications
like barrier, they all worked. So there still might be some settings got
wrong on your environment.

Could you try to run the application on both machine locally? e.g.
"mpirun -np 2 app.exe", probably with full path to the application, just
to make sure that the application could be started locally on each
machine. And try also "mpirun -np 2 -host host1,host2 app.exe" from
both machine, i.e. from both direction.

Regards,
Shiqing
