A WWW search engine called fast speculative search engine that uses speculative execution of multiprocessor systems to shorten the total time to retrieve information from the WWW is presented. This engine predicts the user's next queries and initiates the searches with the predicted queries before receiving them to accelerate narrowing the search space. This fast speculative search engine is implemented using the data speculation on the EM-X, a highly parallel computer which can tolerate communication latency by using low latency communication and multithreading.
