Computer Science 555 - Reading Report #4 -- Fall 2008

Due: Wednesday, November 12, 2008, 11:00 p.m.

• Compare and contrast the kernel architectures for Stanford's V, CMU's Mach, and the Denali hypervisor with the Unix or Linux kernel.

• Highlight the similarities and differences. Consider for each system issues of abstraction, extensibility, performance, communication, and heterogeneity. Discuss the placement of services and functions between he Kernel and user level processes.

• Note: For Unix or Linux, although not specically covered in the reaidngs, you should understand the kernel struction from the undergraduate level operating systems course you took.

INSTRUCTION:

The report must be submitted by 11:00 p.m. on November 12 The report should be approximately 3 pages, or roughly 1200 to 1500 words. To submit your report you will use the DEN Blackboard assignent submission mechanism. You will use this method regardless of whether you are an on-campus student or a DEN student.

How to submit Reading Report #4:

• STEP 1. Please login to DEN, and select csci555.
• STEP 2. Please select "Assignment" in the menu.
• STEP 3. Please select "view/Complete Reading Report #4".
• STEP 4. Please select "File To Attach" to attach your report. (NOTE: PDF, MS WORD, ASCII TEXT ONLY! Other formats are NOT acceptable.)
• STEP 5. Please select "Submit" button. (If you select *SAVE* button instead of *submit*, then the TA cannot view your report for grading.)

It is the individual student's responsibility to follow the submission instruction. Submissions that do not follow this instructions, e.g., submitted late, or only "Saved" and not submitted. may be penalized or may not be graded at all.

Students may receive an automatic extension of 24 hours on exactly one of the assignments during the semester. If you turn in one of your assignments late, then you will not have this extension to use on subsequent assignments. (In answer to questions I have received - if you turn in your assignment within 15 minutes after the deadline, we will only count that as using half of the free late submission, leaving you with a 12 hour extension for another assignment; Since the research paper proposal is not graded, it can be turned in late without coutning against the free late assignment allowance).

GUIDELINE:

This is a lot to cover in so few words - so our advice is to write a first pass at your answer that is longer, and then edit out material that is redundant or not to the point. The use of tables can be very effective in conveying your ideas in a small area, but the tables must be integrated with your textual discussion, and not the only item in your submission.
