Course Assistant for the Operating Systems Needed

I am seeking a course assistant for the Operating Systems course.

Your tasks may vary according to your academic grade, knowledge and understanding of the course materials (and related fields) and your availability. however, basically

• assistance in grading
• assistance of students working in the lab (aka "enshu")
• Work as a 'tester' on the problems (to find out any mistakes/typos)

We can discuss and negotiate the detail. The class schedule is from Wednesday 2nd and 3rd periods.

The pay rate follows the university standard (750/h and 1000/h for undergrad and grad, respectively).

thank you

Advanced Operating Systems

An email message was sent to all-masters email list. The email notified the following two points: (1) the contents and the syllabus of the course are currently under revision and (2) we need to order the textbook (Modern Operating Systems 4/e by Andrew S. Tanenbaum) to the university bookstore.

If you are interested in this course but did not receive the email (e.g. you start the master's program from this fall), please contact the instructor ASAP.

OS Exercise 9 graded

Exercise 9 have been posted and posted on the Moodle.

Typical points of penalty is "missing explanation (or reason)". For example, in Problem 2 Question 1, just writing "slow" did not give you full mark. You should have said "each memory access (in the program) will incur two extra memory accesses (for page tables)."

If you have any question, please ask the instructor during today's class. (you can ask by email but it may not give you enough time to understand the feedback before the final exam).

OS Exercise 14 posted

The problems for Exercise 14. This is an early release of the problems than usual so that student can start preparation for not only Exercise 14 itself but also for the lecture tomorrow as well as final exam on Friday. If you find any mistakes or types, please contact the instructor.

OS Exercise 8 Graded

Exercise 8 has been graded and posted on the Moodle.

Each "Problem" is given 10pts: (1pt for each blank in Problem 1. 5pts for each Question in Problems 2 and 3).

In Problem 2, some students only obtained part of page table sizes (e.g. only the number of entries, or, the size of entry). The total grade (30pts) is scaled to 100% and posted on the Moodle.

Some students did not follow the submission instructions, which appeared in every Exercise problem sheet; most likely

• Incorrect file name
• Incorrect file type

If you have any question, please ask the instructor (The assistant may seem easy to ask questions, but he can't raise your grade!).

OS Change of cut-off date for exercise submission

We have changed the definition of the cut-off date for the exercise submission: It was

cut-off date is five weeks from the class, or one week before the final exam, whichever comes first

Now

cut-off date is five weeks from the class, or the end of the day before the final exam, whichever comes first

The final exam is planned on Feb 10 (subject to change). Therefore, Exercise 10 and after can only be submitted by the end of Feb 9.
