Software and Hardware Verification

This module introduces state-of-the-art software and hardware verification techniques which are widely used in industry. They are particularly important in safety-critical applications, where system failures can not be tolerated. Designing high quality dependable computing systems is widely believed to be the main challenge in Computer Science. Particular focus is on protocol verification and hardware design verification by model checking and program verification by formalisms such as Hoare logics. These techniques presume formal system specifications and use automated tools for analysing whether a system satisfies the properties required or imposed.

Parallel Computing with Graphical Processing Units (GPUs)

Accelerator architectures are discrete processing units which supplement a base processor with the objective of providing advanced performance at lower energy cost. Performance is gained by a design which favours a high number of parallel compute cores at the expense of imposing significant software challenges. This module looks at accelerated computing from multi-core central processing units (CPUs) to graphics processing unit (GPU) accelerators with many TFlops of theoretical performance. The module will give insight into how to write high performance code with specific emphasis on GPU programming with NVIDIA CUDA GPUs. A key aspect of the module will be understanding what the implications of program code are on the underlying hardware so that it can be optimised. You should be aware that there are limited places available on this course.

Software Reengineering

Software development often involves the improvement and adaptation of “legacy systems” – well-established, business-critical software systems that might have become difficult to maintain over time. This module introduces the skill-set that is required to get to grips with such systems. It teaches you how to reverse-engineer and appraise complex, unwieldy systems by implementing source code and execution analysis techniques. It also presents a range of strategies that can be used to adapt and reengineer such systems to improve their quality and viability.

Data Science with Python

This module starts with a rapid review of basic background mathematics and statistics, and an introduction to Python. The module will then introduce students to a range of statistical and programming techniques and give practice in their implementation and interpretation using Python. It aims to help students develop the knowledge and experience to select and use appropriate techniques for a variety of problems. The emphasis will be on practical application of techniques and knowledge of their scope rather than development of theoretical underpinnings. Areas to be covered include: exploratory data analysis, simple checks on data, statistical data modelling, programming and optimization. Students will also learn the fundamentals of robust data management and reproducible scientific analysis.
