Non-determinism complicates the development and management of distributed systems, and arises from two main sources: the local behavior of each individual node as well as the behavior of the network connecting them. Taming non-determinism effectively requires dealing with both sources. This paper proposes DDOS, a system that leverages prior work on deterministic multithreading to offer: space-efficient record/replay of distributed systems; and fully deterministic distributed behavior. Leveraging deterministic behavior at each node makes outgoing messages strictly a function of explicit inputs.
