Summary on Grant Application Form
Single-chip multiprocessor and multithreaded architectures provide a future alternative path to ever more powerful and complex wide issue out-of-order superscalar processors. Parallelising compilers have shown good automatic parallelisation coverage for numerical applications, but still fail to parallelis general purpose applications due to compile-time intractability. Speculative parallelisation can overcome the compiler's limitations by aggressively executing in parallel programs that cannot be fully parallelised by the compiler. Currently, however, there is no existing compiler theory or technology t< exploit speculative multi-processor parallelism. Also, there is no clear architectural design for a speculative multiprocessor or multithreaded processor. This project aims to develop novel compiler techniques for automatic speculative parallel isation, and to explore a series of architectural design configurations, including speculative multiprocessors and multithreaded processors.
