CS 324: Operating Systems

Fall 2008

News

Here is a practice midterm with solutions. Note that this practice test is more or less a rehash of questions from previous times I've taught this course, so some questions may be more or less relevant to this year's version.

10/8: Sharing does appear to be working. Here are instructions for creating a shared directory on turing so that you can work on programming assigments with a partner

Elevator graphics

Due to compatibility issues with the current version of cs1graphics, I've reverted to an earlier version of the elevator graphics program. It's now available in ~bryan/os/elevators. Probably it's easiest to just use the one in my directory, rather than making a copy for yourself, since you'll need the old version of the cs1graphics library as well. So, a typical execution pipe for e1 might be: 
./people | e1 -g | ~bryan/os/elevators/egraphics.py
Enjoy!

turing

The department's Linux cluster (which lives in Ritter 121) is turing.slu.edu. You can access your account by logging in to a machine in Ritter 121, via a text terminal ssh connection or by using a virtual desktop.

Detailed information on connecting to turing and the features of your account is available at the Math/CS department's website on the Computing Resources page.

Your account comes with a few features: a Backup directory with snapshots of your files at past times, a Share directory for creating sharable files for group work, and a WWW directory accessible at http://cs.slu.edu/~user, where user is your SLU username.
