To provide students with a deep understanding of modern operating system technology, implementation techniques and research issues.
Our approach to achieving this goal is to expose students to advanced topics in operating systems via interactive lectures that examine specialist topics, and selected research papers and their results. Further, students undertake a substantial practical project where they apply their skills to advanced operating system construction. Together, both components give students an advanced theoretical foundation in operating systems, that is re-enforced through practical application.
This course builds upon the basic operating systems course (COMP3231/9201/3891/9283), which provides an understanding of the underlying operating systems which students have implicitly relied upon in developing applications in foundational courses within Computer Science and Engineering, and will rely on in their future careers when developing systems and applications. Advanced operating systems enables students to specialise in operating systems, giving them the background to become operating systems or embedded-systems developers or researchers, either themselves or as part of a team.
This course contributes to the the students graduate attributes in the following ways:
Provide in-depth coverage of modern operating system issues, such as:
We're sensible folk and don't want to exclude smart and hard-working students lightly. Hence, if you fail to satisfy the above prerequisites, but still feel you want to take the course, you're up to it and you're willing to work hard to make up for any missing prerequisites then talk to the lecturers!
A rough outline of the lectures is (subject to change):
Lab work forms a major component of the course. This will be carried out using a take-home hardware kit that can be used in any of the School's Linux labs, or on students own machines.
Labs commence right after the lecture in Week 1. Students will be provided with a Cisco/Linksys NSLU2 (“Slug”) which have an Intel XScale processor conforming to the ARM v5 instruction set.
The Slugs run seL4, a third-generation microkernel developed from scratch by Kevin Elphinstone and his team, part of the Trustworthy Systems (formerly ERTOS) group at NICTA. The kernel is the latest in a series of L4 microkernels designed at Karlsruhe, UNSW and NICTA, and has some revolutionary properties which will be disused in class. Most famously, it is the world's first (and so far only) OS kernel with a formal proof of functional correctness; this was done by the ERTOS team under the lead of Gerwin Klein. The ERTOS engineers and research students are mostly alumni of this course.
The Slugs are connected to Linux hosts running an L4 development environment. OS code is developed and compiled there and then downloaded to the Slug, which present a minimum environment ideally suited for low-level systems programming exercises. Documentation as well as sample code will be provided.
After some ``warm-up'' experiments students will work in groups of two on a project, which constructs various OS components, with the ultimate aim of producing a small (and very efficient) operating system. A series of milestones are defined to aid the implementation.
Milestones and the final project will be demonstrated to School staff and the code submitted for assessment. Complete system documentation will form the final deliverable.
Milestones must be demonstrated at the scheduled demonstration time in the week in which they are due. Both partners must be present and participate in milestone demonstrations. Milestone deadlines missed by no more than one week will cause a loss of 25% of the mark for that particular milestone, if missed by more that one week the penalty is 50%, up to a maximum of two weeks. No submissions/demos will be accepted later than two weeks after the deadline. Furthermore, students will not be allowed to continue with the course unless they have given a satisfactory demonstration of the first two milestones (m0 and m1) within one week of the respective due date!
Alternative projects may be given to some students by special arrangements. The main criteria for this is that the project is at least as challenging as the standard project, and that I am convinced that the student(s) are up to it.
Plagiarism in any form will be dealt with consistent with School (http://www.cse.unsw.edu.au/people/studentoffice/policies/plagiarism.html) and University (http://www.lc.unsw.edu.au/plagiarism/) policies.
There will be a final exam, in the form of a 24h take-home. Students will be given one day to read and analyse two recent research papers relevant to the material covered in the course, and submit a critical report on it. See the previous years' exams for examples.
Supplementary exams will only be awarded in well justified cases, in accordance with School policy, not as a second chance for poorly performing students. In particular, it is highly unlikely that a supplementary will be awarded to students who have actually submitted an exam. Make up your mind whether or not you are sick before submitting!
Supplementary exams will either have the same format as the normal exam, or, at the discretion of the LiC, will be orals. They will probably be held on the day after the written supplementary exams held for other courses.
See the consultation schedule.
The project is the heart of this course, which is all about learning about OS design and implementation “hands on”. It will dominate the workload for the course, and will develop valuable and highly-sought-after systems skills in students. Consequently, the project is the dominating assessment component. The project work counts for 65% of the final mark. Students must contribute equally to the project work. In the case of significantly unequal contributions, the marks of the lesser contributor will be reduced.
The exam contributes 35% of the final mark. A minimum mark of 14 (i.e., 40% of the maximum) is required in the exam to receive a passing grade. This is to ensure that no-one can pass the course on project work alone.
We conduct a detailled on-line survey at the end of each session, in order to identify any shortcomings of the course. This has in the past helped to maintain and improve the quality of the course.
In order to emphasise that we take student comments very seriously, we publish all surveys uncensored, with the possible exception of removing statements other people could find upsetting (the LiC isn't easily insulted ;-). In some cases they are accompanied by comments by the LiC.
COMP9242 is weighted at 6 UoC.
Expectations and responsibilities of students, OH&S and equity and diversity issues are covered in the School's Yellow Form which every student needs to sign.
There is no textbook for this course, as no published book covers the material in sufficient depth. Lecture slides and plenty of handouts will be provided.
The menu bar on the left provides links to all relevant documentation for hardware and software.
Lecture slides and other information can be found under the course's WWW home page at URL http://www.cse.unsw.edu.au/~cs9242/.
Aaron Carroll, David Cock, Alex Kroh, Anna Lyons and Adrian Danis are highly experienced students/staff who will be supporting the course, provide consultations and assess milestone demonstrations.
