In search of speculative thread-level parallelism
Jeffrey Oplinger, David L. Heine, Monica S. Lam · 1999
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 peformance of speculative execution. in particular return value prediction improves the success of procedural speculation, and stride value prediction improves the success of loop speculation.
