Very Efficient Speculative Parallel Architecture
VESPA

    (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.
