Communicating sequential process
Communicating Sequential Processes is a formal concurrency model in which independent sequential processes communicate through channels by exchanging messages.
Go in Action, Second Edition
Communicating sequential processes is a formal model of concurrent computation in which independently executing processes communicate through message-passing channels.
- How it is used
- Coordinates concurrent feed fetching and article storage through message passing rather than manual shared-memory synchronization.
- How deep it goes
- Defines the model and works through Go channels, directional endpoints, buffering, and select without deriving CSP formalism.
- Examples
- Illustrates concurrent RSS feed fetching, channel-based article storage, and a recent-articles JSON endpoint.
- What you can do after
- Apply it via Go channels to pass articles between concurrent fetching and storage goroutines without explicit locking.

Learn Concurrent Programming with Go
Communicating sequential processes (CSP) is a formal concurrency model in which isolated sequential processes interact by exchanging messages through synchronized channels.
- How it is used
- Models concurrent Go programs as isolated goroutines communicating and synchronizing through channels.
- How deep it goes
- Defines isolated state, copied messages, synchronized channels, Go differences, and common channel patterns, while deferring deeper CSP detail.
- Examples
- Uses concurrent Go application diagrams and channel patterns including quit, pipeline, fan-in, fan-out, and broadcast.
- What you can do after
- Apply CSP-style concurrency in Go using goroutines, channels, pipelines, shutdown signals, and channel composition patterns.
