Can I cleanly stop mprime on Linux?

drkirkby · 2021-02-17, 21:34

Is there a way to cleanly stop mprime, such that it writes what it needs to disk, then exits? I can obviously send a kill -9 to stop it, but that's not clean.

If you start mprime with the -m option, the menu is always active, even days later and while in the middle of the test. So, just type 4 and press enter to stop the test, then type 5 and press enter to exit mprime.

EDIT: Or, if you forget the menu option numbers, you can display the menu by just pressing enter.

I usually just use 5 alone. That stops the running workers and saves progress before exiting. 4-<Enter> doesn't work if there are workers that aren't running.

mprime should create save files if you kill it (not kill -9)

Pkill mprime

mprime will respond to Ctrl +C from what I remember.

Run top and press k (and kill the pid with SIGTERM?),

Just run "killall mprime", i.e. send a SIGINT to it. It will save the progess which will take a few seconds. mprime will only lose progress, if you send the SIGTERM too fast (few seconds) after the SIGINT or if the mprime process does not have write permissions.
