OS Exercise and Mid-Term Exam Grades

The assistant posted the grade of Exercise 4 on his page (access is limited from u-aizu.ac.jp domain). We expect to post grades of Exercises 4 and 7 shortly. Also, the mid-term exams have been graded partially; if you would like to know the partial grade, please ask the instructor. Sorry for the delay of grading.

OS Exercise 10 posted

Today's problems have been posted at the Exercise Page . The submission is due at 1100 and we will review the problems during the 2nd period in the classroom (Lecture Hall 204).

OS This Week

The schedule of this week's Operating Systems is similar to the last week:

• Work on the exercise problems during the 1st period at the lab. The length of this exercise class may be extended according to the students' progress. The topics covered by the problems will be multi-level page tables and the page replacement algorithms.
• Move to the lecture hall and review the exercise problems for the rest of 2nd period.
• The 3rd period is for the lecture that covers the rest of Chapter 3 (mainly on Section 3.7 Segementation, but should also review Sections 3.5 and 3.6 which we might have gone too quickly last week). If time allows, we may proceed to Chapter 4 File Systems.

The sections of the textbook mentioned above are your reading assignments.

OS Exercise 9 posted (and today's schedule)

The problem of today's exercise has been posted at the Exercise page. The submission deadline is at 1100 and the schedule of today's class is as follows:

• 9:00 to 11:00 Work on the exercise problems
• 11:00 to 11:30 Break
• 11:30 to 12:10 exercise problem review at M4 (Lecture Hall 204)
• 13:10 to 14:40 lecture at M4 (Lecture Hall 204)

OS This Week

This week, we will work on the exercise problems in Section 3.3 Virtual Memory during the first two periods. The lecture in the third period will cover (and hopefully finish) the rest of Chapter 3 (Section 3.4 Page Replacement Algorithms to the end).

In most classes, the exercise problems complete within the class and you have no homework. You are supposed to spend some time to prepare for the classes next week by reading the appropriate part of the textbook or reviewing the note you took in the class.

OS Exercise 8 posted

The problem of today's exercise has been posted at the Exercise page . There is an opportunity for extra credit. Please ask the instructor if you are interested.

OS This Week

As it was announced last week, we will work on the exercise problem related to Sections 3.1 and 3.2 during first two period. Please come to the lab (std2, or Research Quadrangles 146) in the morning on Wednesday.

During the lecture in the 3rd period, we will cover Section 3.3 Virtual Memory (and possibly proceed to 3.4 Page Replacement Algorithms if time allows).

It is you who can make the class meaningful: if you read these sections and prepare for asking questions, you can gain much more than those who are not prepared for the class.
