[Dedicated to the memory of Professor Phil Dorin, teacher, mentor and friend.]
Concepts in the design of operating systems, including: processes, process management, mutual exclusion, synchronization and message-passing; primary memory management, multiprogramming, paged allocation and paging policies; resource and I/O management; file systems, and security.
This class uses the C
language for its concrete examples, homework, and exams. There
will be some class time spent on introductory-level C
programming. You are more than welcome to ask
for whatever clarification you need at any time, either in class or out. If you require additional practice
with C
, there are any number of online tutorials which you can use to hone your skills. In addition you
can use other professors' web sites [either LMU or other schools] and things like
Code Academy, Kahn
Academy, codingbat.com, and good old
Stack Overflow to help you when you are stuck. And as always, feel
free to come see me during office hours. I have a TON of books about C
programming that I can let you
look at and use in the office during help sessions.
Note that the course description above is not very specific.... there is more detail below!
Programming, like anything else, takes practice and perseverance. You must be willing to make mistakes, to learn how to fix them, and to learn not to be afraid of them. Humans [and now even computers!] learn by making mistakes, and this is the place to do so without fear.
When you finish the course, you will be able to:

In accordance with the LMU Credit Hour Policy, this 3-unit course will require 9 hours of work per week, which includes the time spent in class and lab sessions. This work will consist of homework, a project, watching and commenting on some videos about databases and related topics, and reading/study of textbook material.
There are two textbooks for this course. The first is required, the second is optional:
The first book is a free textbook
which I have downloaded and put on my GitHub repo; because it is
quite literally a free book, you may use for reading and reference and may even download your own copy.
In spite of the fact that it is somewhat dated, the concepts in it are fundamental to the understanding of
operating systems, and they are presented clearly so you can understand them rather easily. Besides, it's
free.
The other book will be used for ancillary material. It is VERY good for you to have a copy on your own programmer's bookshelf in some form, because it is full of lessons to help you write high-quality and easily maintained code.
THE BOOKS ARE NOT AVAILABLE IN THE LMU BOOKSTORE. They are available at many other fine retail outlets, both online and brick-and-mortar. We will be using them for homework assignments, and for general reading and information.
Although we won't be covering the books in their entirety for this class, we will be using them as primary resources.
There is also a large number of other resources which can be used to "mine the gold" for related
information about data structures. The topic is a very broad field, which has been around for a
very long time, and touches almost every aspect of compjuter science. Any google search on data
structures
will turn up at least ten million links. Many of these will be shared during class, and
you will be required to find some information about specific topics on your own. You may even be
required to use the LMU library, [GASP!!] so be prepared!
A list of topics that are covered, and the approximate order and time frame in which they will be discussed, is available on the class notes page for this site.
Chapter readings from the text books and the dates by which these readings should be completed are listed below. Note that you should have read the chapter material prior to the date listed, and you should be ready to discuss the text, ask questions about the concepts, and begin working with some of the implementations of the concepts in class. It is also a good idea to at least read (or preferably try) the exercises contained in [and at the end of] each chapter.
Here is the reading list:
All written homework assignments are due at the beginning of the class on the date
they are due. Deviation from this process requires prior consent of the instructor. I left my
homework at home
is not a valid reason for late work. This is college, and you can be
responsible for remembering what you need to remember. Every effort is made to ensure assignments,
required deliverables, and due dates are prominently posted on these pages; it is your
responsibility to make sure you know what is due and when it is due.
You may certainly turn assignments in late; I will happily accept them, but they will be reduced in
grade by one letter for each day they are late. Day
means day
, not
workday
or class day
; an A+
homework due on Thursday which is not
turned in until the following Tuesday will unfortunately only earn a failing grade, unless some prior
arrangements are made with the instructor due to illness or some major schedule conflict. However,
if you want to turn something in late, I'll still provide feedback even for assignments which have no
chance of any credit; I keep this policy to allow you to get the learning benefit of the assignment
even if you don't get a grade for it. My philosophy is that it is important for the students to know
the material, even if an assignment doesn't get the best marks.
All assignments which are to be printed out for submission must be printed on a printer. Details for this requirement are provided for each assignment on the individual assignment's page. All assignments must use proper American English and/or Programming Language spelling and grammar. Failure to do so will cost you a letter grade, so get a spell-checker and a grammar checker, or find a friend who is proficient to proofread your work before it is submitted.
Other than these simple rules, there are no requirements for formatting, fonts, colors, diagrams, or anything else with respect to your homework assignments, other than good code craftsperson-ship.
There will be three homework assignments during the semester, due on the dates shown in the list below. Each assignment will contain several excersises to help give you experience with the concepts covered. Each of these assignments is detailed on a separate web page; they are available from the links below. Solutions will be provided after ALL the assignments are handed in. This policy provides a motivation for everyone to turn assignments in on time, since NO ONE gets the solutions until EVERYONE has submitted their work. Homework will be done in groups of three, since much of the homework involves programming assignments. It is EXPECTED that you will work independently from other groups, although discussion of the concepts is encouraged. Computer science is a collaborative enterprise, but you will be responsible for your own work on the submission of all your assignments. Each link below takes you to the web page for that assignment
There will be no formal quizzes. There will be no midterm exam.
There will be a final exam. Grades for the course will come from your homework
assignments, your participation in the class including in-class exercises, and your semester project, as
well as your final exam. The final exam will be open everything
except neighbor, because this is
hard stuff.
There will be a semester project for this course. You will be required to download and install a copy of Linux from source code. This means you will need a virtual machine for your computer. The semester project will include documenting and implementing some functionality into the Linux kernel, and demonstrating it to the class in some fashion. The final project due date is the week before finals week, so you will have the entire semester to implement it. The project is to be done using triumvirate programming which means you will be working with two partners on this effort for the entire semester. Your homework will be done using the same group as your project group, so there will be three of you collaborating on the homework assignments, too.
You will need access to a computer of some variety. …Well, Duh… If you don't have a computer available, let me know and I will try to work with Masao to get something set up for you using a VPN to a computer in the Keck Lab on campus. You'll still be remote, but you'll have access to SOMETHING to work on. In the best of all possible worlds, we will all have super-duper computing engines to use, but we're obviously not there yet… |
You should also note, that installing and building Linux will require a large amount of hard disk space, somewhere around 40 GB of space on the local drive. While it is not required that ALL THREE of the members of each project group build Linux, AT LEAST ONE MEMBER of the team will need to have that much space on the local drive of the computer being used. Start early to back up your data so you can clean them off your hard drive, if you need to do so, to insure you have the needed space when the time comes! Also be aware that you should do this project together as a group; don't try to parse it into pieces, because it doesn't work that way.
Although attendance is not mandatory, it is in your own best interest to attend every class. Much of the material will be discussed and elaborated upon in class, so counting on the books for all required information will not provide you with complete information. In addition, there will be in-class exercises in small groups which you will miss out on if you are not there.
Obviously, if you skip too many classes, you will likely fail; this is a simple and self-fulfilling prophecy.
The class participation rubric appears with the grading stuff in the tables below.
There will be no extra credit given in this course.
Grades for the course are assigned according to the weighting factors shown in the tables below.
Final letter grades will be assigned based on the following scale:
Percent | Letter | Rating and Achievement |
---|---|---|
91 - 100% | A- / A | Professional quality work; outstanding |
81 - 90% | B- / B / B+ | Entry-level quality work; above average, shows extra effort and interest |
71 - 80% | C- / C / C+ | Satisfactory work; expected with reasonable effort |
61 - 70% | D | Substandard work; minimal effort shown |
60 or less | F | Thank you for playing; see you next semester |

Also of note…
An incomplete will be granted only when the student requesting the incomplete has completed at least 80% of the coursework, and has at least a B average in the course work completed. This is standard LMU policy.
Leave of Absence/Withdrawal Policy:
Please read the revised policy in the University Bulletin.
All work is evaluated for both technical merit and quality of written and/or oral presentation.
Find yourself a good spelling and grammar checker, or a trusted human editor, if you
are having any difficulty with the rules of standard English language usage. Another excellent resource
is the Academic Resource Center, located
on the south side of Daum Hall. The center takes appointments, and also allows drop-in consultation
sessions, and they have a number of good benefits. Call (310) 338-2847 to schedule an appointment.
(For those that don't know, Daum Hall is the building where the LMU Security and Parking office used to
be. ARC is on the second floor.)
Another thing to remember is, your coding style is an important part of your assignment evaluations. I WILL NOT HESITATE to take points off for code that has hard-coded number

Electronic Devices: Pretty easy — please turn off your cell phone ringer during class time. That's it for me! However…
The official LMU language for this is:
Please turn off and put out of sight all electronic devices (other than those and when allowed) during class-time. The interruptions and/or distractions they cause disrupt class and interfere with the learning process. Even if you are not on video, it's distracting to you.
Netiquette. Your instructor and fellow students need a safe, online learning environment. All opinions and experiences shared, no matter how controversial they may be perceived to be, must be respected in the spirit of academic discourse. You are encouraged to critique an idea but should not attack an individual. Working as a community of learners, we can build a respectful space for discourse. Below are some tips for good netiquette:
Sendbutton.
Students and faculty have a reasonable expectation for privacy in all learning spaces. Bimodal and remote learning can involve the use of synchronous video conferencing, asynchronous recorded lectures, live and online discussions, as well as online forums. In these venues, privacy is a priority for a safe learning environment. See Lion's code.
As a member of our online community, please follow these privacy guidelines:
Because of the nature of the class delivery method
during remote zoom times
we will
also take a look at a document which will serve as a guide for everyone in the class. This
Netiquette Document
is published here
and on the Brightspace
site for this class. We will take a look at it during the first week of class and will work to make
it agreeable to everyone involved.

I am also always available by e-mail at: my LMU mail address
There is a class slack channel on the LMUCS workspace, named cmsi-284_spring2021
. I post to that
channel with information at times, and it's a good place to ask/answer questions. It won't hurt you to
join! You can also DM me in that workspace.
Beginning in Fall 2020, the LMU CS department is trying a new communication method using Discord for our
virtual office hours, and as a virtual Keck Lab
environment. Feel free to join up there as well,
and post there with your colleagues in the department!
YOU MUST CHECK YOUR LION EMAIL ADDRESS OF RECORD. I will
start the semester's communications by sending all email blasts to everyone's lion.lmu.edu
email
address, which is known as your address of record. If you specifically
provide me with a preferred alternative email to use I will be happy to oblige. I create a distribution
list to which I send all general communications in addition to the slack channel, so it is important for
me to have an email address which you will check on a regular basis.
If necessary, this syllabus and its contents are subject to revision. Students are responsible for any changes or modifications announced or distributed in class, emailed to students' LMU Lion accounts or posted on LMU's course management system, Brightspace. If you are absent from an in-person or online class meeting, it is your responsibility to check Brightspace [and/or the course website] and to check with the professor to see if you missed any important class announcements. Students should not rely on word-of-mouth from classmates.
