Java Multithreading and Parallel Programming Masterclass - Crushing Matrixes with Barriers

The lecture introduces the concept of a cyclic barrier, a synchronization tool that allows threads to wait for each other before proceeding. It explains the basic functionality, methods, and features of cyclic barriers, including the use of a Runnable parameter. An example is provided using 2D arrays, where threads process columns and synchronize using the barrier. The implementation details are discussed, including handling exceptions. The lecture concludes with the execution of the example, demonstrating the cyclic barrier's utility in parallel algorithms.
