A fast, scalable and extensible actor system.
- Fast: Up to 630 million msg/sec on a single node 1. Up to 20 million msg/sec single threaded performance.
- Scalable: Includes a decentralized cluster manager to avoid single point of failure.
- Extensible: Built on top of a custom-made plugin system which allows inlining of plugin code into the main event loop. Multithreading is a plugin. Actor migration is a plugin. Even last-mile message delivery is a plugin. If something is not a plugin, that's a bug.
Circo also features Infoton Optimization, a physics-inspired solution to the data-locality problem (See the paper).
There is a monitoring tool named "Camera Diserta" which can help to tune Circo applications and to research Infoton Optimization.
Please note that Circo is in alpha stage. It is more like a research tool at the time than a mature platform. The documentation is also far from complete. Contributions are welcome!
