CL0610/Java-concurrency
Java Concurrency
Cette bibliothèque de concurrence Java fournit une suite d'outils pour gérer l'exécution multi-thread, la synchronisation et la cohérence de la mémoire. Elle sert de framework complet pour implémenter l'exécution concurrente via des atomiques sans verrou, des collections thread-safe, des primitives de coordination de tâches et des pools de travailleurs.
Le projet inclut une boîte à outils de synchronisation de threads dédiée comprenant des verrous, des barrières et des sémaphores pour coordonner le timing et l'ordre des tâches concurrentes. Il fournit également une suite de collections concurrentes de maps, files d'attente et listes qui permettent le partage de données sans verrouillage manuel, ainsi qu'un framework d'opérations atomiques pour les mises à jour sans verrouillage des types de base et des références.
La bibliothèque couvre de vastes domaines de capacité, incluant la gestion de pool de threads pour optimiser l'utilisation des ressources, l'analyse du modèle de mémoire pour assurer la visibilité des données et divers mécanismes de gestion de verrouillage pour prévenir les conditions de course. Ces outils soutiennent collectivement le développement d'applications multi-thread qui maintiennent des transitions d'état cohérentes à travers la mémoire partagée.
Features
- Java Concurrency Frameworks - Provides a comprehensive framework for implementing multi-threaded execution, synchronization, and memory consistency in Java.
- Java Concurrency Frameworks - Serves as a comprehensive Java library providing structured concurrency primitives and synchronization tools.
- Async Coordination Primitives - Provides coordination primitives such as latches, barriers, and semaphores to synchronize the timing of concurrent tasks.
- Lock-Free Primitives - Provides lock-free primitives including compare-and-swap (CAS) for high-performance atomic updates to shared variables.

- Atomic Primitives - Implements a framework of lock-free utilities for atomic updates to basic types and references.
- Memory Consistency Models - Implements synchronization guarantees based on memory consistency models to ensure data visibility across threads.
- Thread Pools - Implements executor-based thread pools to optimize system resource utilization and task scheduling.
- Thread and Process Synchronization - Provides a toolkit of latches, barriers, and semaphores to coordinate the timing and order of concurrent tasks.
- Shared Resource Synchronization - Prevents race conditions using synchronization primitives like monitors, semaphores, and volatile variables.
