Description:
CSE 421/521 is an introductory course on the design and implementation
of operating systems. It will focus on different OS design techniques, process
management, processor scheduling, concurrent programming, deadlocks and
synchronization, memory management, file management and I/O systems, disk
scheduling, protection and security, and distributed systems. The course will
include hands-on programming projects on different OS components. (Prerequisites of this course: CSE 250, or
an equivalent course, or permission of the instructor.)

Lecture time & location : Tue, 5pm – 7:40pm (Knox 110)
Exam schedule : Midterm 1: October 17th @5pm-6pm (Knox 110)

Textbook:
(Required)
v Operating Systems Concepts (9th or
10th edition),
by A. Silbershatz,
P.B. Galvin, and G. Gayne. Wiley Publishers..
ISBN: 978-1-118-06333-0
Recommended Supplementary Text: (Optional)
v
The C
Programming Language. By Kernighan
and Ritchie. Prentice Hall, Second Edition, 1988, ISBN 0-13-110362-8.
v
Advanced
Programming in the UNIX Environment, by Richard Stevens. Addison Wesley Press, 1993, ISBN 0-201-56317-7.
Grading:
The end-of-semester grades for this course will be composed of:
v Pop Quizzes: 5%
v Homework: 5%
v Project-1: 20%
v Project-2: 20%
v Midterm-1: 25%
v Midterm-2: 25%
* There will be no formal attendance taken in the class. But, you are expected to attend the classes and actively contribute
via asking and/or answering questions.
Pop
Quizzes:
There may be pop quizzes at the beginning of some classes. The questions
in the quizzes will come mostly from the material discussed in the previous lecture(s)
or homework assignment(s). The quizzes will be very short (5-10 min) with one or two questions
aiming to test whether you have understood the most recently discussed material
in the curse. There will be 5 pop quizzes throughout the semester. One with the
lowest grade will be discarded, and the rest four will count towards your final
degree.
Homework:
There will be four homework assignments throughout the semester. The
format of the homework questions will be similar to
the exercises at the end of each chapter in the Silberschatz
book. The homework assignments aim to ensure that you read the textbook and
study regularly for the material covered in the class.
Projects:
There will be two hands-on programming projects throughout the course.
These projects will be based on “pintos” instructional OS developed at Stanford
University and aim to teach implementation of some core Operating System
components for better understanding of the concepts. These will be “team”
projects and they will require strong programming background in C and UNIX programming
experience.
Piazza
Discussion Forum:
We will be using
Piazza for class discussion. The system is highly catered to getting you help
fast and efficiently from classmates, the TA, and myself. Rather than emailing
questions to the teaching staff, I encourage you to post your questions on Piazza.

Academic Integrity Policy:
UB’s definition of Academic Integrity in part is, “Students
are responsible for the honest completion and representation of their work”. It
is required as part of this course that you read and understand the departmental
academic integrity policy located at the following URL: https://www.buffalo.edu/academic-integrity/policies.html
There is a very fine line separating conversation
pertaining to concepts and academic dishonesty. You are allowed to converse
about general concepts, but in no way are you allowed to share code or have one
person do the work for others. If you are caught violating the academic integrity
policy, you will minimally receive a ZERO in the course.
* PS: We are using professional software which can easily
detect any cheating attempts in programming projects. The results generated by
this software is considered as official evidence for cheating from another
student, or from internet or any other resource.
