Java Multithreading and Parallel Programming Masterclass - Parallel Matrix Multiplication - The Optimal Way

The lecture introduces block matrix multiplication, a parallelization approach for matrix multiplication. It explains the concept, benefits, and implementation details, focusing on using tasks and semaphores for synchronization. The lecture also compares the performance of this approach with a serial version, highlighting its efficiency and memory trade-offs.

In what ways can the block matrix multiplication algorithm be improved?

How does the block size affect the performance of the multiplication tasks?

What are the potential trade-offs when implementing the block matrix multiplication algorithm?

What role does the semaphore play in the synchronization of tasks?
