Assignment

Under what circumstances do page faults occur? Describe in detail the actions taken by the operating system when a page fault occurs.

Consider a system that uses pure demand paging.

When a process ?rst starts execution, how would you characterize the page-fault rate?

Once the working set for a process is loaded into memory, how would you characterize the page-fault rate?

Assume that a process changes its locality and the size of the new working set is too large to be stored in available free memory. Identify some options system designers could choose from to handle this situation.

Length: 1-2 pages (excluding the title page and reference pages) and double-spaced.

The following items will be assessed in particular:

1. Your ability to consolidate ideas from reading materials and your understanding of the materials.
2. Your ability to write a report with strong argument.
3. Some in-text references to modular background readings.
