摘要： A loop can be executed on a parallel processor by partitioning the loop iterations into chunks of decreasing size. An increase in speed can be realized by reducing the time taken by a thread when determining the next set of iterations to be assigned to a thread. The next set of iterations can be determined from a chunk index stored in a shared variable. Using a shared variable enables threads to perform operations concurrently to reduce the wait time to the period while another thread increments the shared variable.
摘要翻译：可以在并行处理器上执行循环，将循环迭代分为大小减小的块。通过减少线程在确定要分配给线程的下一组迭代时所花费的时间，可以实现速度的提高。可以从存储在共享变量中的块索引确定下一组迭代。使用共享变量可以使线程同时执行操作，以减少等待时间，而另一个线程会增加共享变量。

摘要： Methods and apparatus for reducing memory latency in a software application are disclosed. A disclosed system uses one or more helper threads to prefetch variables for a main thread to reduce performance bottlenecks due to memory latency and/or a cache miss. A performance analysis tool is used to profile the software application's resource usage and identifies areas in the software application experiencing performance bottlenecks. Compiler-runtime instructions are generated into the software application to create and manage the helper thread. The helper thread prefetches data in the identified areas of the software application experiencing performance bottlenecks. A counting mechanism is inserted into the helper thread and a counting mechanism is inserted into the main thread to coordinate the execution of the helper thread with the main thread and to help ensure the prefetched data is not removed from the cache before the main thread is able to take advantage of the prefetched data.
摘要翻译：公开了一种用于减少软件应用中的存储器延迟的方法和装置。所公开的系统使用一个或多个辅助线程来预取主线程的变量，以减少由于存储器延迟和/或高速缓存未命中引起的性能瓶颈。使用性能分析工具来描述软件应用程序的资源使用情况，并识别遇到性能瓶颈的软件应用程序中的区域。编译器运行时指令生成到软件应用程序中以创建和管理辅助线程。辅助线程预取了遇到性能瓶颈的软件应用程序的已识别区域中的数据。计数机制被插入到辅助线程中，并且计数机制被插入到主线程中以协调辅助线程与主线程的执行，并且有助于确保在主线程可用之前预取数据不被从高速缓存中移除以利用预取的数据。
