Lesson 1
Our Goals for this Lesson
In this lesson, we'll look at the critical section problem and some classic synchronization mechanisms that address both that problem and the need to wait for certain conditions to be met. We'll examine semaphores, monitors, and locks & condition variables, seeing motivated them and how they work. We'll also look at the thread-level synchronization primitives in OS/161.
