This paper focuses on the problem of how to find and effectively exploit speculative thread-level parallelism. Our studies show that speculating only on loops does not yield sufficient parallelism. We propose the use of speculative procedure execution as a means to increase the available parallelism. An additional technique, data value prediction, has the potential to greatly improve the performance of speculative execution. In particular, return value prediction improves the success of procedural speculation, and stride value prediction improves the success of loop speculation.
