Duration: Full-time 1 year. Part-time 1.5 years

Core Modules
Concurrent and Parallel Programming

The future of microprocessor development is based around multi-processor multi-core architectures that will deliver the performance required for future application demands. The difficulty for software developers is how to write programs that harness the power of these new architectures. As a result the fundamental aim of this module is to teach learners how to write software for these machines. The general module aims are to provide learners with an understanding of the need for, and advantages of, concurrent and parallel systems; to master a new programming paradigm that is different from that of the single threaded one; a description of how processes and threads are managed in multi-processor, multi core machines; an understanding and mastery of the many classical problems arising with concurrent and parallel tasks; an awareness of the need for such issues as fairness, process synchronisation, deadlock avoidance, etc.; the ability to write concurrent and parallel programs to solve real world problems; an understanding of multi-core architectures and their significance for the implementation of parallel systems; a mastery of notations to express solutions to parallel problems.

Dissertation / Dissertation by Practice

Each learner must complete a project proposal for validation by a panel of project supervisors. Once approved, the learner may commence their project work. The project proposal is the output from the Research Methodologies section outlined below.

All proposals submitted should be no more than 2,000 words describing what is intended to be done and offer a review of current research in the area together with a literature review. A project proposal should be more than just a documented idea. Learners must demonstrate that they have carried out some outline research on their proposal and have considered the appropriateness, technical complexity, feasibility and scope of their proposed project. This work should be completed under the guidance of the supervisor.

Research Methods

This module serves to significantly deepen the learner's research skills, both in relation to the module related assignments and later in the completion of a dissertation / dissertation by practice. Specifically, it extends the ability of self-directed learners by equipping them with the appropriate vocabulary for reflecting on, critiquing and evaluating their own work and that of others. Throughout the module, learners are required to engage in a number of research methodologies and current research issues and trends in computing science. The module also addresses the need for good project management skills and techniques for the successful delivery of any project.

Telecommunication and Network Services

This module aims to provide you with an understanding of the issues involved in the design and analysis of telecommunication networks, as well as a knowledge of such systems in terms of physical implementation, protocols, routing algorithms, management, software interfaces, and applications. The course also focusses on high speed telecommunication networks.
