Due to technological limitations, it is proving increasingly difficult to maintain a continual increase in the performance of individual processors. Therefore, the current trend is to integrate multiple processors on to a single chip and exploit the resulting parallel resources to achieve higher computing power. However, this may require significantly different approaches to both hardware and software particularly for general purpose applications. This course will explore these issues in detail.
Learning outcomes are detailed on the COMP35112 course unit syllabus page on the School of Computer Science's website for current students.
