Welcome to the fall 2022 session of CSC 213: Operating Systems and Parallel Algorithms. In this course, we will learn what is happening a level of abstraction below your programs when you run them on a modern computer. We will learn how the OS and runtime libraries providing useful services to programs, how the OS manages scarce resources like CPU time and memory, how access to storage and network devices is controlled, and the role that hardware plays in each of these concerns.
