SSH forwarding is already working in my normal 'non-SGE' environment through the use of ssh-agent. The issue with the environment the job starts and runs in. Since my key requires a password, I can't just add those lines to the start of my job script.
I think the only solution is to configure passphraseless SSH between all cluster nodes. I just wanted to confirm that, if possible, with others before starting down that road.
