Linearizability

Correctness condition making operations appear atomic.

How it works

Each operation appears to take effect atomically at a point between its invocation and response, consistent with real-time order; it is the gold standard consistency for concurrent objects.

Where it is used

Verifying concurrent data structures.

Common pitfall

Composable but expensive in distributed settings.

Where it fits in the course

Linearizability is topic 48 of 51 in Concurrency & Parallelism, rated Advanced. It follows Backpressure. The next topic is Memory Models in Languages.
