Goals and Objectives

This course gives an introduction to the basic concepts used to structure modern computer operating systems. The goal of the class is to explain those concepts and principles that are likely to survive for many years to come. The course is a departure point for research in operating and distributed systems. Specifically, the course introduces the concepts of processes, concurrency, synchronization, scheduling, multiprogramming, memory management, and file systems.

Requirements

You are responsible for the material covered in lecture, as well as the assigned readings. Questions on homework assignments and examinations will be based on both material covered in class as well as assigned readings.

Textbook:	Operating System Concepts, by Silberschatz, Galvin and Gagne. 7th Edition, Wiley & Sons.
Assignments:	Homework: roughly one written problem set due weekly, each completed individually; Projects: three programming assignments, each completed in groups or individually; Exams: midterm examination (7/16, 4-5:20p), and a final exam (8/02, 8-11a).
Lectures:	Available online and subject to change. Changes will be announced in class and updated on Web page.

Policies

Collaboration: Unless otherwise noted, all work must be completed individually. Homework assignments may be discussed, but solutions must be completed individually. Projects may be completed in established groups, and implementation approaches may be discussed across groups, but programming code cannot be shared across groups.

Grading: Homework: 20%; Projects: 30%; Midterm: 20%, Final exam: 30%.
Cheating: Don't do it. All students are required to know and adhere to the UCSD Policy on Integrity of Scholarship (near middle of the page). Failure to do so will result in consequences outlined in the UCSD Policy.
