Very Efficient Speculative Parallel Architecture

(VESPA, Portuguese for "wasp") An Edinburgh University project using speculative multithreading to improve single-application and multiprogramming performance, and to increase fault tolerance and reliability. The project aims to develop a compilation environment to generate efficient speculative parallel code, including speculative parallelisation and speculative helper threads. Other research involves the development of optimized thread-level speculative architectures and novel uses of speculative multithreading, such as fault-tolerance.
