Course Description:

This course introduces the logical design of operating systems, especially focusing on the design in Java. Topics covered include processes, threads, CPU scheduling, synchronization, deadlocks, memory management, virtual memory, file systems, I/O systems, protection, and security used in the popular desktop and real-time operating systems.

  1. Operating System Concepts with JAVA, 8th edition, Abraham Silberschatz, Peter Galvin, and Greg Gagne, Addison-Wesley, 2009.
  2. A Java book of your choice.

Some Java Books:



All programs except the final project are to be done independently. Any collaboration of work will result in severe penalty. You may discuss the problem statement and any clarification with each other, but any actual work to be turned in, must be done without collaboration.

The final project may be done by a team of two, (or three students if you cannot find a single partner), in which case each student must achieve an equally amount of work. (If you work with other two students, you must explain the reasons in your report, otherwise you will receive only 2/3 of the full score.) For the detailed instructions, see the project assignment sheet.

Any homework is due at the beginning of class on its due date. Only a soft copy must be submitted. The submission may be postponed only in emergencies such as accidents, sickness, sudden business trips, and family emergencies, in which case you may turn in your homework late with a written proof. No make-up exams will be given except under exceptional circumstances. Barring emergencies, I must be informed before the exam.

If you have a documented disability on file with the DSS office, please have your DRS counselor contact me and we can discuss accommodations.

Course Goals:

The overall goal of CSS 430 is to learn fundamemtal concepts that are used in and applicable to a variety of operating systems. The course consists of three major concepts: (1) process management that schedules, executes, synchronizes with events, and terminates your application programs, (2) memory management that loads your programs in memory and allocates/deallocates memory space they requested dynamically, and (3) file system that provides the mechanism for on-line storage of and access to both data and programs residing on the disks. The course also covers protection, (and security if time is allowed) which are essential to have the modern operating systems work in the Internet computing world. Through the course, we will use Java to illustrate many operating-system concepts. Using Java, you will implement each concept of process management, memory management, and file system. As with most technical courses, besides ability and motivation, it takes time to learn and master the subject. Expect to spend an additional 10 to 15 hours a week outside of class time on the average.


Class Discussions:

Each chapter has its own lecture slides in a ppt file that includes one or more discussion topics and non-turn-in exercises. The class is divided into groups of 4 or 5 students, each discussing about a different topic for several minutes and presenting the dicussion summary in the class. We are planning to have eight or more class discussions through the quarter, although not having scheduled specific discussion dates yet. Your participation in each discussion counts 0.5% of your entire grade, which ends up with 4% by attending minimum eight discussions. If we eventually have more than eight dicussions and you attend all of them, you will receive extra credits.

A discussion group will be dynamically formed in the class. For instance, students sitting closer or on the same desk can form a group. I will give each group a piece of scratch paper or transparency. You should summarize your discussions, write down the names of all group members, and turn it in to me. Each group should elect a group representative who will give a short presentation in the class. A representative will be rewarded with 0.1 extra credits for his/her presentation.
