Unconventional memory model extensions in practice
summary
Covers practical use of Java memory-model semantics in real-world code: examines how different Java concurrency guarantees are applied, analyzes the Disruptor library, and shows how to implement a custom, sometimes faster, lock-free queue. Targets multithreading, memory models, and popular lock-free libraries.
