Helper for interactive jobs with snakepit.
Add your SSH public key to .compute and modify .real_compute to suit your needs.
./run-interactive.sh <job name> <job allocation> will start a job, wait for it
to run and SSHD to be available, then forward a local port to SSHD on the job
and connect to it, attaching into the existing tmux session that is running
on the job. If you're on macOS running on iTerm2, it'll use iTerm2's tmux
integration. You'll then be attached into the session running .real_compute
and can go from there. Commands executed in the interactive shell and their
outputs will be logged to |pit log| normally. If you create new tmux panes/
windows, those won't be logged into |pit log|. This can be fixed, patches
welcome :)
If available, uses autossh to automatically restart the SSH session if the connection drops.
