    • According to one embodiment, a program converting device includes an access attribute determining unit, a non-sharing target classifying unit, and a converting unit. The access attribute determining unit calculates exclusive accesses from memory accesses by threads forming a source program and determines a memory access using a cache memory among the calculated exclusive accesses. The non-sharing target classifying unit determines an access data item that does not share a cache line with another access data item among the access data items that are accessed using the cache memories. The converting unit inserts a process that does not share the cache line into the source program based on the determination result of the non-sharing target classifying unit.
    • 根据一个实施例,程序转换装置包括访问属性确定单元,非共享目标分类单元和转换单元。 访问属性确定单元通过形成源程序的线程来计算来自存储器访问的独占访问,并且在所计算的独占访问中使用高速缓存存储器确定存储器访问。 非共享目标分类单元使用高速缓冲存储器访问的访问数据项中的另一访问数据项目来确定不与高速缓存行共享高速缓存行的访问数据项。 转换单元基于非共享目标分类单元的确定结果将不共享高速缓存行的处理插入到源程序中。
