CPS 210
Operating Systems

The first two labs for this semester are subsets of the Nachos labs used in the undergraduate OS course.

A detailed Nachos lab guide is available online:

• lab guide - HTML with no frames
• lab guide - pdf
• lab guide - postscript

Justin's Nachos page offers supplementary materials relating to Nachos for CPS 210 (e.g., where to get it, how to hand in the labs).

Please post questions relating to the labs on the course newsgroup.

Lab 1: Threads, Synchronization, and a Simple Kernel
