Process Throttler

This script is designed to be run as a cron job on HPC login nodes and similar, where you wish to restrict long-running CPU/memory-intensive processes - they should be using compute nodes to run these!

For processes using more (on average) than the specified amount of CPU or memory:

1. are reniced to the maximum value (19) after renice_after seconds
2. are killed after kill_after seconds

Individual users and process paths can be excluded.

Setup

CentOS 7

Run build_centos.sh to create an rpm package that can be installed using yum.
