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

Thanks Shiqing!

Unfortunately, it still doesn't work, but I've got more info.

I can use wmic to start an application on the remote machine, but that
application does not start in the current login process (notepad.exe
starts, but I have to ask task manager to show all processes to find it,
even though I'm currently logged in as the same user). I believe this
is expected behavior, please let me know if it's not.

When using mpirun, I can verify that orted starts on the remote machine,
but the crash or hang appears to happen before the application starts
execution. Oddly, orted does not appear to start on the local
machine. Logs all refer to mpirun crashing.
