Topics

Here is the list of topics covered in this course. They will be mapped to chapters from the text as the course progresses.

The reading material for the various chapters are as follows:

You might check out the assignment timeline to help you plan for doing homeworks, projects and exams.


Slides

Slides from the in-class lectures will be available shortly after they are presented, depending upon how things go.

Here is what we have so far:


Homework

There will be 4 short homework assignments. Homeworks are to be turned in individually. Discussion of problems among students is encouraged, but when it comes to ultimately solving the problem, your answers must be your own.

Homework and due-dates will be placed here as they are defined. Here is what we have so far:


Projects

The projects (I often call them labs) are the programming assignments you will have for the course. I encourage you to work in groups of two for the projects. I'd prefer to limit the groups to only 2, but if you really want a larger group, come talk to me. Working in groups will give you valuable ``real-world'' experience as well as provide you with a ``built-in'' source for help. Do remember, however, that all exams will be taken alone. Make sure each group member understands the programs completely!

The projects and due-dates will be placed here as they are defined. Here is what we have so far:

With the exception of project 0, you will need to turn in your assignments on-line. Check here for information on how to turn in your assignments.


Samples

In this section are any code samples discusses in class, practice exams or any other demonstration-type class materials.

Final exam stuff:

Mid-term exam stuff:

Here is the simple "Bite Me" client-server example that shows the use of the socket wrappers used in Project 3:

Here is the simple "Up Yours" client-server example that shows the use of threads as in Project 4. They use the same socket libraries as the client-server sample above:

Here are the demos that have separate add and subtract threads that access a global variable:

Here are some samples showing the use of software signals:

Sample code from the Simple Operating System:

Process stuff:

Semaphore and shared mem stuff:


OS Hotlinks

Linux

Linux is a completely free Unix operating system. Linux runs primarily on 386/486/Pentium PC's but has been ported to various other architectures. If you like Unix, want to learn more about system administration and have access to a PC, I recommend checking it out. Read a short info sheet or a more detailed info sheet for more information.

I, Cringely

A weekly column by Robert X. Cringely that provides a humorous but profound look at the world of Information Technology.
"What makes Cringely such an interesting writer is the way he combines a solid understanding of technology, the ability to explain it simply, and an irreverence for those who, at the highest levels, hawk it" IEEE Spectrum, May 1997.

Nachos

Your text book mentions the Nachos System in the Appendix (pages 699-714). Although this system is too advanced for an intro course on operating systems, keen students may like to look further into the Nachos software. Some useful course material (e.g. slides, notes, Java simulations, etc.) includes: You can also have a look at the Yahoo! Operating Systems pages and related WWW pages: Or perhaps you would like to know more about some of the companies involved in Operating Systems:
