Course Overview

This course gives an introduction to the basic concepts and core principles 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.

Prerequisites
600.120 (Intermediate Programming), 600.211 (Unix Systems Programming), 600.226 (Data Structures), 600.233 (Computer Systems Fundamentals). This course involves significant kernel programming tasks. You should: 1). be comfortable and fluent in programming in low-level languages (C and x86 assembly in particular); 2). have experiences of developing in UNIX environment.

Organization

This course is organized as a series of lectures taught by the instructors, assigned readings, discussion sections, homework, projects, and exams. They are complementary to each other, helping you reinforce learning on the core concepts in operating systems. Questions on examinations will be based on material covered in class, assigned readings, and projects.

Lectures: Core material of the course.
Readings: The textbook and supplementary readings provide references to lectures, and are good preparations before class. But they are not a substitute for the lectures. In other words, you should come to class.
Projects: Five programming assignments, each completed individually or in groups (of no more than 3). They are essential for you to turn the theories you learned into practices.
Homework: Optional homework questions for exam preparation (not to be turned in)
Exams: Midterm examination and a final exam

Grading

Your final grade for the course will be based on the following weights:

  • Projects: 50%
  • Midterm: 15%
  • Final exam: 35%

For the programming assignments, there are no partial credits. You must turn in working code.

Policies

Collaboration
Unless otherwise noted, all work must be completed individually. Homework assignments (if any) 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.
Cheating
Don’t do it. All students are required to know and adhere to the JHU CS Department Academic Integrity Code and university policies. Failure to do so will result in serious consequences outlined in the policy. Simply stated, do no cheat. The consequences are very high for the time/effort saved.

Acknowledgments
