The work
- The lectures will cover topics in operating systems and the topic of systems generally. The schedule is here.
- The labs are a crucial component of this course and are described here. You will implement, help implement, or interact with, a number of the abstractions described below.
- The exams are described here.
- The readings are listed on the schedule and should be completed before class. The required and optional texts are listed below.
- The homeworks (as distinct from the labs) are intended to reinforce the course material.
We assume that you check the announcements on this site every 24 hours. Also, we will use Campuswire (join the class at that link). Finally, we will occasionally email you (for the most urgent communications). You are responsible for monitoring all three of these media.
A note about the labs
We recommend that you start the labs long before they are due. The standard advice is "Start the labs early", but that is not quite right. The best advice, we think, is "Start the labs on time, but on time is probably much earlier than you think it is".
Description and goals
We hope you learn three sets of interrelated things. The first thing is how computers work. Students graduating with CS degrees should believe "there is no magic": they should be able to describe the chain of events that occurs when they hit a key and cause a letter to appear on the screen from the register level (or logical gate level or transistor level) to the system architecture level to the operating system level to the application level. This is philosophically important, but it is also of practical interest to developers who need to figure out how to make a system do what they want it to do.
The second goal is for you to learn the core ideas in operating systems: concurrent programming, memory protection, virtual addressing, file systems, scheduling, transactions, etc. Often, such ideas are best explained as abstractions that some software layer (usually the operating system) provides above imperfect hardware to make that hardware usable by programmers and users. The intent is for you to understand such abstractions well enough to be able to synthesize new abstractions when faced with new problems.
Many of the ideas and abstractions that we will cover are relevant not only to operating systems but also to large-scale systems. Thus, a third goal of this course is to enhance your ability to understand, design, and implement large-scale systems.
The coding workload in this class will be substantial. This is a necessity: understanding many of the ideas above requires implementing them or working through them in code. The good news is that if things go according to plan, you will learn a lot in this class, and ideally find it rewarding. For example, you will learn how operating systems are implemented, and how to effectively use the abstractions exported by operating systems.
