Concurrency with Python: CSP and Coroutines > Ying Wang

BRANK

Overview The concept of communicating sequential processes, or CSP, is similar to the notion of actor models, but brings added utility to contemporary concurrency challenges. Both of these concurrency models leverage message passing, but whereas actors pass messages between containers of state, the CSP model passes messages between channels, a form of synchronization and communication between coroutines or coroutine-like processes. Russ Cox has a great writeup about the history of CSP.
