This paper presents a helper thread prefetching scheme that is designed to work on loosely coupled processors, such as in a standard chip multiprocessor (CMP) system or an intelligent memory system. Loosely coupled processors have an advantage in that resources such as processor and L1 cache resources are not contended by the application and helper threads, hence preserving the speed of the application. However, interprocessor communication is expensive in such a system. We present techniques… CONTINUE READING
