CSC 213, Fall 2006 : Schedule : Lab 9

Lab 9: Memory, Files, and Protection

Goals: This laboratory exercise provides some practice with issues related to memory management, virtual memory, file management, security, and protection.  

During our lab section meeting, we will discuss a classic paper, "Hydra: The Kernel of a Multiprocessor Operating System" by Wulf et al. (1974).  Our goal is to consider in some depth a protection mechanism that is an alternative to those that are commonly used today.  This paper should also remind you of a number of topics we've already seen.

Collaboration: You will complete this lab individually.  You may consult me or your classmates with proper attribution.
