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.
|Unit title||Unit code||Requirement type||Description|
The unit aims to:
Explore the various software and hardware issues brought by the current trends of integrating multiple processors on to a single chip in order to tackle the single-core processors speed stagnation through parallelism.
Describe the main issues, along with key proposed solutions, in the design and construction of chip multi-processor hardware (e.g. multi-core CPUs and GPUs) and related programming languages.
evaluate a number of specific examples of extensions to programming languages supporting the writing of correct and efficient code on shared memory multi-processors.
compare a number of extensions to hardware structures supporting, for example, memory coherence, synchronization, speculation and transactional memory, to improve the performance of code executing on chip multiprocessors.
Compare a number of extensions to programming languages and supporting user- and operating system-level data structures to improve the performance of code on chip multiprocessors.
evaluate the effectiveness of concurrency support in a popular programming language, including the use of threads, locks and barriers, in the context of experience gained with three simple parallel programming exercises.
Trends in technology, limitations and consequences. The move to multi-coreParallelism in programs, ILP, Thread Level, Data Parallelism.
