You can use screen to detach a session. You connect to your ssh server, launch screen and then your computation...

At your next connection, screen -a to attach previous sessions

Another idea would be to use tmux which works like screen but it is more flexible and easier to use (in my opinion). To keep a process running you could simply start a tmux session with the command tmux.

This will "open a new terminal" in which to run your programs, if you want you can give a name to the session to easily find it in case you have multiple sessions with the command ctrl+b $ instead of using the default name (e.g. 0).

After running the programs you need in the tmux session, you simply detach from the session with ctrl+b d and go back to the normal terminal from which you can call exit and close your ssh connection.

When you log in again, you simply run tmux attach -t <session_name> to go inside the session where you left your tasks running.

tmux offers a lot of other functionalities too, like screen splitting inside the session with ctrl+b % or ctrl+b " for vertical and horizontal splitting. (you can move between different screens with ctrl+b <arrow in the direction of the screen you want to go to>.

All these Answers are correct but if you are initiating SSH from a code and giving bash commands then they don't work. The best way is to use this command

nohup command > /dev/null 2>&1 &
