When using someone else's machine, it's polite to use the command nice and renice.
Nice changes the priority of a task. When using another machine, you want to set your task to a lower priority as to not interfere with the user's tasks. Priority ranges from -20 (highest) to 20 (lowest).
nice [options] [command]
Example:
nice -19 ~/run.py
UNIX priority levels are counted from negative (highest) to positive. Note that nice -n specifies a priority of n whereas nice --n specifies a priority of -n.
Renice allows you to reset the priority of a process that is already running.
renice [-n] [PID] [options]
Replace [-n] with the desired priority, and [PID] with the process ID number.
