Welcome to your first the Wisconsin Operating Systems course. This course will describe a number of topicsincluding basic operating system structure, process and thread synchronization and concurrency, file systems and storage servers, memory management techniques, process scheduling and resource management, system security, and a few other "hot" topics. This course assumes familiarity with basic computer organization (e.g., processors, memory, and I/O devices as covered in cs354) and data structures (e.g., stacks and hash tables). You will need to be able to program in C (not C++, and definitely not Java) to perform the assignments in the course. If you don't have much experience in this language, don't worry (too much), we will spend some time covering background, but of course, learning on your own is important and valuable (in this class and in real life). For those of you who are new to C (e.g., you just know Java), realize this is an opportunity to broaden your skill set! (i.e., stop complaining).


We recommend coming to class and reading the book in advance, before we cover a topic in class

You should have the following textbook:

Operating System Concepts (7th Edition)
Silberschatz, Galvin, Gagne
ISBN: 0-471-25060-0
You should also own:
The C Programming Language (2nd edition)
Kernighan and Ritchie
ISBN: 0-13-110362-8 (paperback)
Prentice Hall

Here is a short, free, and incomplete overview of the C programming environment by Andrea Arpaci-Dusseau as a PDF.

It would also be useful to figure out how to use the debugger, gdb. Here is a link to a short tutorial -- there are others on the web too. Learning how to use such tools is a good idea.


In this course, you will be doing group progects. More information is available on the project page.


There will be 8 quizes during the discussion section over the course of the semester. The lowest score will be dropped. The quizes will be closed-book, closed-note and will cover material from the lecture and readings.


There will be two writing assignments during the course of the semester to introduce you to advanced OS topics. You will be expected write a 3 -5 page paper describing recent advances or the state-of-the-art in an OS-related area.


There will be an optional final. For the exam, a single page "cheat sheet" (8.5 by 11 inches) is allowed, and you can use both sides; exams are otherwise closed-book and closed-note .


Without Final With Final
20% Writing 15% Writing
30% Quizzes 22% Quizzes
50% Projects 38% Projects
25% Final

Assignments are due at the start of class on the date listed on the handout. Late assignments will receive no credit .
