(in reversed chronological order)
- 7/23/2013:
The final exam will be closed book,
closed notes, and closed everything (and no "cheat sheet").
Also, no calculators, cell phones, or any electronic gadgets are allowed.
Please bring a photo ID. Your ID will be collected at the beginning
of the exam and will be returned to you when you turn in your
exam. There will be assigned seating.
The final exam will cover everything from the first slide of
Lecture 9 on 6/24/2013
to the last slide of Lecture 16 on 7/22/2013.
(Please note that shared libraries (Ch 3) will not be part of the final exam coverage.)
Regarding what types of questions will be on the midterm, please see
the Exams section of the course description web page.
Here is a quick summary of the topics (not all topics covered may be listed):
- Ch 1 - Introduction
- Ch 4 - Operating-System Design
- devices
- virtual machines, microkernels
- Ch 5 - Processor Management
- threads implementations
- interrupts
- scheduling (up to and including stride scheduling)
- Ch 6 - File Systems
- the basics of file systems
- crash resiliency
- directories and naming, RAID, flash memory, case studies
- Ch 7 - Memory Management
- 7/17/2013: Office hour today is moved to 12-1pm in OHE 132 (right after class).
Sorry about the inconvenience.
- 7/8/2013: The statistics for the Midterm Exam are:
Count = 50
Avg = 42.90
StdDev = 7.21
Max = 55.00
Min = 26.00
1 54+ X
5 51+ XXXXX
10 48+ XXXXXXXXXX
6 45+ XXXXXX
7 42+ XXXXXXX
8 39+ XXXXXXXX
6 36+ XXXXXX
1 33+ X
2 30+ XX
3 27+ XXX
1 24+ X
Since the maximum possible score is 60, to get your normalized
score (i.e., normalized to 100 points), you need to divide your
score by 60 and then multiply by 100. (The same goes with the
class average. Therefore, the normalized class average is 42.98/0.6=71.5.)
- 6/19/2013:
The midterm exam will be closed book,
closed notes, and closed everything (and no "cheat sheet").
Also, no calculators, cell phones, or any electronic gadgets are allowed.
Please bring a photo ID. Your ID will be collected at the beginning
of the exam and will be returned to you when you turn in your
exam. There will be assigned seating.
The midterm exam will cover everything from the beginning of the
semester till the end of Lecture 8 on 6/19/2013.
Regarding what types of questions will be on the midterm, please see

Important Information about Programming Assignments
|
The programming assignments of this class will be very demanding.
You will be required to write C code. Since C is
a proper subset of C++, knowing C++ well would give you enough
background. However, some of the things that available in C++,
such as strings and streams, are not be available in C. So, you need
to know how to do things such as
manipulating null-terminated array of characters
(using functions such as strchr, strrchr, strlen, strcmp, strncpy, etc.)
and performing console and file I/O
(using functions such as printf/snprintf, fread/fwrite, read/write, fgets, etc.)
in C.
No other programming language will be accepted.
We will not teach C in this class.
You are expected to pick up C on your own if you are not familiar with it.
You should also get familiar with the UNIX
development environment (vi/pico/emacs, cc/gcc, make, etc.)
The kernel programming assignments must run on Ubuntu 11.10. Therefore, you
should install Ubuntu 11.10 on your laptop or desktop, if you have one.
If you do not have a personal laptop or desktop that runs Windows or Mac OS X, please contact
the instructor.
If a student signs up late for this class or could not be present
at the beginning of the semester,
he/she is still required to turn all projects and homeworks
on time or he/she will receive a score of 0 for these assignments.
No exceptions!
