Robinwaita

Robinwaita is user-friendly round-robin process scheduler for Linux written in C. It comes with a modern Libadwaita & GTK 4-based user interface.

Details

• Easily add processes to the scheduling queue
• Round-robin scheduling algorithm, with context switches initiated by timerfd
• Bundled Python processes to test CPU-bound, I/O-bound, and "mixed"-bound operations
• See how processes get managed by the algorithm in real-time
• Modern GTK 4 & Libadwaita interface with light and dark modes
• Check basic statistics like total context switches in a separate tab

Motivation for this project

• Given the additional low-level programming experience I've been getting recently, as well as my growing experience with operating systems concepts, I wanted to challenge myself by programming a process scheduler from scratch.
• I've also loved GNOME and its technologies like GTK for several years. I've thought about making a GTK app for a while now, so combining the two seemed like a fun fit. While the user interface for this project wasn't the focus, I'm still really happy with how it turned out.

Dependencies

• Robinwaita has been developed with the following versions of these packages:
  • libadwaita/libadwaita-devel version 1.5
  • libgtk-4-dev/gtk4-devel 4.14
  • libglib2.0-dev/glib2-devel
  • libgio-unix-2.0-dev/gio-unix-devel 2.0
  • libgraphene-1.0-dev/graphene-devel 1.0
  • python3-dev/python3-devel 3.12.6
  • gcc 14.2.1
  • cmake 3.28.2
  • pkg-config/pkgconf-pkg-config
• Other versions may work, but I provide no guarantees.
• I provide an ARM64 build under Releases, but it's expected your system still satisfies dependencies above.
• My build environment was a Fedora 40 VM under Parallels on my M2 Pro-based MacBook Pro.
