Subject: Re: [OMPI devel] Launch windows nodes from linux
From: Ralph Castain (rhc_at_[hidden])

Guess I'm confused. The launcher is running on a Linux machine, so it has to use a Linux service to launch the remote daemon. Can you use ssh to launch the daemons onto the Windows machines? In other words, can you have the Windows machine support an ssh connection?

I did a quick search and found a number of options for supporting ssh connections to Windows. Here is one article that describes how to do it:

http://www.windowsnetworking.com/articles_tutorials/install-ssh-server-windows-server-2008.html

Once the daemon is started on the Windows machine, it will automatically select the Windows options for starting its local procs - so that shouldn't be an issue. The issue will be figuring out a way to get the daemon started.
