How keep running a program n an another computer via a connection ssh when the connection is closed?

Hi everybody,

I am running a program on a supercomputer via my personal computer through a ssh connection. My program take more than a day to run, so when I left work with my PC I stop the connection with the supercomputer and the program stop.

I am wondering if someone know how I can manage to keep my program running on the supercomputer even if the connection with my computer is closed?

Thancks in advance!
Cheers Thomas

Hi,
start your program in the background and protect it from the HUP-signal, which causes it to stop when you close your connection to the remote machine.
Code:
nohup /path/to/your/program &

This will of course only work for non-interactive programs.
Edit: in case your program needs human interaction have a look if the tool screen is installed on the remote machine.

Ask the supercomputer guys ("superusers") if they have a solution.
For terminal sessions reconnection there is screen to be installed on the supercomputer.
