Speculative High Performance Computation on Heterogeneous Multi-Core

Abstract

Thread level speculation has been proposed and researched to parallelize traditional sequential applications on homogeneous multi-core architecture. In this paper, a heterogeneous multi-core hardware simulation system is present, which provides with TLS execution mechanism. With a novel TLS programming model and a number of new speculative tuning techniques, benchmarkGzipis parallelized from-3% to 195% on a four-core processor, and the speedup of the test benchmarks are 30%, 43% and 156%, respectively with arbitrary, hotspot and insight speculation.
