Many of the most important and visible uses of computer technology rely on distributed computing. This course unit aims to introduce students to the principles, techniques and methods of distributed computing in sufficient breadth and depth for it to act as a foundation for the exploration of specific topics in more advanced course units. The course unit assumes that students have already a solid understanding of the main principles of computing within a single machine, and that they have a rudimentary understanding of the issues related to machine communication and networking.

Learning Outcomes

On completing the course, a student should:

Have knowledge and understanding of the main principles, techniques and methods involved when dealing with distributed systems.
Have detailed knowledge and understanding of major issues related to the design of a distributed system, such as:
- how to communicate between distributed objects by means of remote invocation
- the absence of global physical time in distributed systems
- how processes can coordinate their actions in a distributed setting distributed transactions.
Have the ability to design and implement prototypical distributed computing applications using different technologies.
Be aware how the fundamental techniques above are applied in practical systems.

Assessment of Learning outcomes

1) and 2) assessed by examination. 3) assessed via laboratory exercises. 4) not formally assessed unless used to illustrate answers to examination questions.

Contribution to Programme Learning Outcomes

A3, C1, C5 strongly. A2, B1, B2, B3 moderately. D1, D4, D5 slightly.
