Stateline is a framework for distributed Markov Chain Monte Carlo (MCMC) sampling over a cluster of machines. It uses parallel tempering to run a large number of chains in parallel, taking advantage of the cluster to evaluate computationally intensive likelihood functions. Stateline uses the library to provide fault-tolerant network communication.

Stateline comes with a headless server that can connect with workers using ZeroMQ. The communications protocol is simple enough that the workers can be written from scratch in any language that supports ZeroMQ.
