This course is based on the foundations set by the previous course on computer organisation. It expands particularly into all forms of concurrent programming including aspects of massively parallel programming.
This course introduces all basic mechanisms to analyse, design, and manage concurrent, single computer-node (multicore) as well as distributed applications (e.g. as performance or dependability enhancements).
Following on from the previous course, the fields of operating systems and networking will also be expanded on. On the operating system side aspects of security, scheduling algorithms and memory management are discussed. More specific networking aspects follow on from message passing as a core concurrency construct. These include the basics of routing and dependable protocols.
Upon successful completion, students will have the knowledge and skills to:
- Model, design and program concurrent systems.
- Select appropriate modeling techniques, tools and mechanisms to solve a range of problems in concurrent and distributed systems. This includes the appropriate programming language and runtime environment for the task at hand.
- Analyse and debug concurrent programs.
- Understand the aspects of an operating system concerning scheduling, protection and memory management.
- Employ message passing locally and over networks to construct distributed systems
- Distinguish as well as connect conceptual concurrency with physical parallelism at all levels of a distributed system.
- Identify core aspects of operating systems and networks irrespective of the specific system at hand.

ANU has educational policies, procedures and guidelines , which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Integrity Rule before the commencement of their course. Other key policies and guidelines include:
- Academic Integrity Policy and Procedure
- Student Assessment (Coursework) Policy and Procedure
- Special Assessment Consideration Guideline and General Information
- Student Surveys and Evaluations
- Deferred Examinations
- Student Complaint Resolution Policy and Procedure
- Code of practice for teaching and learning
The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the Academic Skills website. In rare cases where online submission using Turnitin software is not technically possible; or where not using Turnitin software has been justified by the Course Convener and approved by the Associate Dean (Education) on the basis of the teaching model being employed; students shall submit assessment online via ‘Wattle’ outside of Turnitin, or failing that in hard copy, or through a combination of submission methods as approved by the Associate Dean (Education). The submission method is detailed below.
Moderation of Assessment
Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.
The assessments in this course demand hands-on training. Without attending tutorials and submitting and testing the laboratory exercises every week, the students will find it extremely hard to finish the assignments. Therefore, we expect high participation in the tutorials. Each lecture will offer an in-class quiz which will prepare students for the final exam. Therefore, attending the lectures and participating in the discussions and solving the quiz questions is extremely important.
There will be a final exam worth 50%. The exam will cover the course content covered in lectures in the first eleven weeks.
Assessment Task 1
Learning Outcomes: 1, 2 , 3 ,4
Memory Allocator Design
In this assignment, students will implement a memory allocator, which allows users to malloc() and free() memory as needed. Their allocator will request large chunks of memory from the OS, and efficiently manage all the bookkeeping and memory.
Assessment Task 2
Learning Outcomes: 5, 6, 7
HTTP server design
The second assignment in this course requires students to implement a HTTP server that will allow a HTTP client (a web browser like FireFox or Google Chrome ) to connect to it and download files.
Assessment Task 3
Learning Outcomes: 1, 2, 3, 4, 5, 6, 7
There is only one examination in this course. The final exam will be held during the exam period.
Academic integrity is a core part of the ANU culture as a community of scholars. The University’s students are an integral part of that community. The academic integrity principle commits all students to engage in academic work in ways that are consistent with, and actively support, academic integrity, and to uphold this commitment by behaving honestly, responsibly and ethically, and with respect and fairness, in scholarly practice.
The University expects all staff and students to be familiar with the academic integrity principle, the Academic Integrity Rule 2021, the Policy: Student Academic Integrity and Procedure: Student Academic Integrity, and to uphold high standards of academic integrity to ensure the quality and value of our qualifications.
The Academic Integrity Rule 2021 is a legal document that the University uses to promote academic integrity, and manage breaches of the academic integrity principle. The Policy and Procedure support the Rule by outlining overarching principles, responsibilities and processes. The Academic Integrity Rule 2021 commences on 1 December 2021 and applies to courses commencing on or after that date, as well as to research conduct occurring on or after that date. Prior to this, the Academic Misconduct Rule 2015 applies.
The University commits to assisting all students to understand how to engage in academic work in ways that are consistent with, and actively support academic integrity. All coursework students must complete the online Academic Integrity Module (Epigeum), and Higher Degree Research (HDR) students are required to complete research integrity training. The Academic Integrity website provides information about services available to assist students with their assignments, examinations and other learning activities, as well as understanding and upholding academic integrity.
The assignment submission will be through the teaching Gitlab. You will be required to electronically sign a declaration as part of the submission of your assignment. Please keep a copy of the assignment for your records.
The two assignment submissions in this course will be soft copy submissions. We are aiming for in person (paper) exams. We will adjust the policy as per circumstances.
Individual assessment tasks may or may not allow for late submission. Policy regarding late submission is detailed below:
- Late submission not permitted. If submission of assessment tasks without an extension after the due date is not permitted, a mark of 0 will be awarded.
The Academic Skills website has information to assist you with your writing and assessments. The website includes information about Academic Integrity including referencing requirements for different disciplines. There is also information on Plagiarism and different ways to use source material.
Extensions and Penalties
Extensions and late submission of assessment pieces are covered by the Student Assessment (Coursework) Policy and Procedure. Extensions may be granted for assessment pieces that are not examinations or take-home examinations. If you need an extension, you must request an extension in writing on or before the due date. If you have documented and appropriate medical evidence that demonstrates you were not able to request an extension on or before the due date, you may be able to request it after the due date.
Distribution of grades policy
Academic Quality Assurance Committee monitors the performance of students, including attrition, further study and employment rates and grade distribution, and College reports on quality assurance processes for assessment activities, including alignment with national and international disciplinary and interdisciplinary standards, as well as qualification type learning outcomes.
Since first semester 1994, ANU uses a grading scale for all courses. This grading scale is used by all academic areas of the University.
