The SLURM Workload Manager is an open source, fault-tolerant and highly scalable cluster management and job scheduling system[1] used on the DEAC cluster. Formerly known as Simple Linux Utility for Resource Management (aka SLURM)[2], it provides three key functions:

Allocates exclusive and/or non-exclusive access to resources (compute nodes) to users for X period of time
Provides a framework for starting, executing, and monitoring work on allocated nodes
Arbitrates contention for resources by managing a queue of pending jobs

Chimera is a general-purpose OS born from unhappiness with the state of Linux distributions. It's built around the core idea that a simple system does not have to require endless setup and customization to be practical.

It aims to capture the convenience of complex distributions while retaining conceptual simplicity. To this purpose, it is built from scratch using novel tooling and approaches.

Portable and heterogeneously-accelerated graphical visualization for radio signals.
