Linux: Prevent a background process from being stopped after closing SSH client

I'm working on a linux machine through SSH (Putty). I need to leave a process running during the night, so I thought I could do that by starting the process in background (with an ampersand at the end of the command) and redirecting stdout to a file.

Android - Running heavy computations in background and returning the result to an Activity

I have implemented some computationaly heavy functions into my application. Depending on the type of input it can take up to several minutes for a thread to return. During this time, I want the user to be able to work with other activities to perform different tasks (i.e. prepare data for the next run). Then, after the Service has finished it's computations, the user should be notified with a Toast that the result is ready and that he should check back to the Activity he started the Service in. Unfortunately I'm stuck at this point.
