No, not GIMP, but GIMPS: the Great Internet Mersenne Prime Search.
I’d been starting mprime from rc.local, but this time I used crontab, as suggested in that thread, to reduce the program’s privileges.
Start the crontab editor:
crontab -e
Then add this line:
@reboot ( /opt/Primenet/mprime & )
It starts every time the box boots and run until you hit shutdown, which is exactly the way things should work.
Power dissipation looks like this:
- Idle: 40 W
- mprime running: 88 W
They estimate an additional 40 W, which comes out slightly low for this box. Their system info dump looks like this:
