Research on binary-level speculative multithreading for general-purpose multi-core processors

通过引入一种基于程序执行路径的推测多线程执行方法，提出了一种针对推测多线程的线程级并行化方法，该方法既可以扩展线程代码，又可以消除线程之间的数据通信。开发了一个软件原型系统，解决了基于程序执行路径的高性能线程级并行化的开发，(2)低成本的软件精确路径规划系统的开发，(3)仅靠软件实现高性能的推测多线程。

This research developed a method of thread-level parallelization for the speculative multithreading, that enables both the enlargement of thread codes and the removal of the data communication between threads, by introducing a speculative multithread execution method based on the execution path of programs. A software proto-type system have been developed, while solving the three primal problems (1)development of the high-performance thread-level parallelization based on the execution path of programs,(2)development of the software accurate path profiling system at low cost,(3)realization of high-performance speculative multithreading only by software.
