Non-blocking Synchronization
Explore non blocking synchronization techniques in Java multithreading to improve performance and scalability. Understand how atomic instructions like compare and swap enable lock free algorithms that avoid deadlocks and reduce thread blocking. This lesson helps you build thread safe counters without locks and compare their performance with lock based methods, preparing you to implement complex concurrent algorithms efficiently.
We'll cover the following...
Introduction
Much of the performance improvements seen in classes such as Semaphore and ConcurrentLinkedQueue versus their synchronized equivalents come from the use of atomic variables and non-blocking synchronization. Non-blocking algorithms use machine-level atomic instructions such as compare-and-swap instead of locks to provide data integrity when multiple threads access shared resources. Non-blocking algorithms are harder to design and implement but out perform lock-based alternatives ...
