screen
screen is a useful tool to keep long time tasks (a.e. magma, matlab) running on a computer without keeping your session online during the whole computation:
- Initial Start:
open a console and connect through SSH to the machine you want to run the task on (most likely: compute.math.uzh.ch) by typing the host name: [user@tlX] compute and enter your password (there is a script called 'compute' which does nothing else than 'ssh compute' - in our evironment it's not necessary to type 'ssh compute')
type screen <application name> . F.e.: screen maple
- Detach:
to detach from screen ("send it to background"), press Ctrl + A + D
- you now can log off from the terminal and your task will keep running
- Attach again:
- if you want to check progress of your computations, log into the machine where your task is running like you did before
use screen -raAd to connect to your task
