history

Project history and usage

cpulimit is a small process-control utility that limits a process's observed CPU usage percentage without changing its nice value or scheduler priority.

Project history

The README credits Angelo Marletta as the developer and describes the tool's goal: prevent a process from running for more than a specified CPU time ratio. The official GitHub repository was created in 2012.

Adoption history

cpulimit has remained packaged as a straightforward Unix-style utility for administrators and users who need to tame batch jobs. The input package metadata shows distribution through Homebrew and several Linux package managers.

How it is used

cpulimit controls CPU consumption by sending SIGSTOP and SIGCONT POSIX signals. The README notes that child processes and threads of the selected process share the configured CPU percentage, and documents simple make-based builds for Linux, OS X, and FreeBSD.

Why package nerds care

The package is significant because it solves a familiar operational problem with a tiny C tool and no service manager dependency: package it once, expose a single executable, and users can apply soft CPU throttling to existing processes.

Timeline

  • 2012: The opsengine/cpulimit repository was created.
  • Repository era: v0.1 and v0.2 tags exist in the official GitHub repository.
  • 2024: The official repository was still receiving updates.

Related projects

  • cpulimit is related by purpose to Unix process-management tools such as nice and schedulers, but the README distinguishes it by controlling real CPU usage through stop/continue signals rather than priority.
