We have proposed multi-processor architecture, called SKY, which efficiently executes multiple threads in parallel. In particular, the SKY efficiently executes programs which have fine-grain thread-level parallelism(TLP), such as non-numerical programs. Although the SKY achieves performance improvement over the superscalar processor which has about as much cost as the SKY, the SKY does not exploit TLP effectively enough. This paper evaluates speculative thread execution on the SKY to mitigate the constraint of control and data dependences. We also introduce a new thread partitioning technique which considers value prediction which is used to mitigate the constraints of data dependences, and evaluate it. Our results show that the speculative thread execution achieves performance improvements by 12.7\% in SPECint2000 or by 12.3\% in MediaBench over conventional non-speculative thread execution. However, our new thread partioning technique achieves little improvement compared with a conventional thread partioning technique. |
