Outline of Final Research Achievements

This research develops a method of global speculative multithreading based on the frequent program execution paths in order to highly speed up non-numerical programs by fully utilizing the potential performance of multi-core processors that recently have becomes widespread. For speculative multithreading on entire program codes globally, major essential technologies are developed by extending our previous path-base speculative multithreading method. The three major outcomes of this research are as follows: (1)development of a global path-based thread decomposition method that can parallelize entire program codes across the subroutine/procedure boundaries within program code, (2)development of a program profiler that can collect and analyze the global execution information of target programs, (3)development of an execution environment to support the global path-based speculative multithreading.
