This repository contains open source code for Karma, a new resource allocation mechanism for dynamic demands. Karma introduces a new credit-based resource allocation algorithm with powerful theoretical guarantees related to Pareto efficiency, strategy-proofness, and fairness under dynamic demands, that have been shown to translate well into practice. For a full technical description of Karma, please refer to our OSDI'23 paper.

This repository contains the following three components:

• algorithm/: Efficient implementation of the Karma algorithm provided as a library for easy integration with applications.
• simulator/: Simulator that can execute Karma and other relevant schemes over input demand traces for easy testing and exploration.
• jiffy-implementation/: End-to-end implementation of Karma on top of a distributed elastic memory system (Jiffy)
