renice-like tool for non-root users to increase OOM adjust?

Question

Is there anything like renice for OOM adjust? That is, something that would allow a non-root user to increase (but not decrease) the OOM score adjust of processes they own?

Answer 1

We have choom now.

tl;dr: choom --adjust -100 myprogram.

The man page has more information.

Answer 2

There's not anything that does it as a program, but that's when scripting comes in, write a script that finds any PIDs started by their UID, then lets them pick the process, and echoes -1000 (for example) to /proc/<pid>/oom_score_adj.

You can then make it a root only executable, and allow sudo access to the people who need it.
