Run the job under "nohup" (no hang-up).

For instance,

Code

nohup mpiexec -n 4 /opt/atk/bin/atk script.py > log.py &

Note that some instances of mpd produces a huge amount of error messages in the log when you run in the background unless you pipe stdin also. In that case, use

Code

nohup mpiexec -n 4 /opt/atk/bin/atk script.py > log.py < /dev/null &

I always use the command screen.

Type screen to get a seperate thread in linux/unix shell. Start the ATK and all as usual. When done press ctrl-a followed by d. It will detach the screen.
If you ever need to bring this thread back just type screen -r.
