Concurrent Slogon

Do not communicate by sharing memory; instead, share memory by communicating.

Although Go’s approach to concurrency originates in Hoare’s Communicating Sequential Processes (CSP) ,it can also be seen as a type-safe generalization of Unix pipes.

• Rob Pike’s concurrency slides (IO 2012)
• Video of Rob Pike at IO 2012
• Video of Concurrency is not parallelism (Rob Pike)

Concurrency

Channels

• Buffered Channel
• Unbuffered Channel

Goroutines

Goroutines run in the same address space, so access to shared memory must be synchronized​​. The sync package provides useful primitives, although you won’t need them much in Go as there are other primitives.

How are Go channels implemented?
