Speculative Threading: Creating New Methods of Thread-Level Parallelization

Overview

This paper discusses the factors that are driving the need for speculative threading. It will then explain a new speculative threading model developed within Intel's research labs. Preliminary performance results using this model indicate the potential for significant processing gains with only a small increase in power requirements. Tomorrow's computing workloads from RMS and other applications of the future will require exponential increases in computing power. Multi-core platforms and multithreading are paving the way to meeting these performance needs. To do it though, they require a companion effort in accelerating the development of the thread-level parallelism necessary for reaching their full performance potential.
