    • A program parallelization supporting apparatus determines a determinacy in at least one dependency relationship of a data dependency, a control dependency and a pointer dependency in a program, extracts a critical path in the program, and extracts a processing instruction which exists on the critical path and has a non-deterministic determinacy in the dependency relationship. Furthermore, if a process related to a path of the extracted non-deterministic processing instruction is parallelized and the path of the non-deterministic processing instruction is deleted, the program parallelization supporting apparatus outputs parallelization labor hour information depending on the number of dependency relationships disturbing the parallelization and parallelization effect information depending on the number of processing instructions which are shortened by the parallelization.
    • 程序并行化支持装置确定程序中数据依赖性,控制依赖性和指针相关性的至少一个依赖关系的确定性,提取程序中的关键路径,并提取存在于关键路径上的处理指令, 在依赖关系中具有非确定性的确定性。 此外,如果与所提取的非确定性处理指令的路径相关的处理被并行并且删除非确定性处理指令的路径,则程序并行化支持装置根据依赖关系的数量来输出并行劳动时间信息 并行化和并行效应信息取决于通过并行化缩短的处理指令的数量。
