A clustered task distribution system
ReplCache: variable caching in the cloud

A simple clustered task distribution system

This is an article on placing a task into a grid (cluster) where it is picked up and processed by a worker, based on a deterministic algorithm.
No task is lost; when a node crashes, the remaining nodes again deterministically pick a worker which processes the task again.
There is no single point of failure, and nodes can be added (e.g. to accommodate more load) and removed without interruption of the system. The article can be found at here (PDF) and here (HTML).
The source code is here.
