Abstract:

We propose a generic architectural framework, a multi-threaded run-time system for client/server architectures, which facilitates the integration, exchange and extension of various prefetching techniques. To demonstrate the viability of this architecture two prefetching techniques are incorporated: a predictor-based technique---which consists of a separate predictor component in the run-time system---and a code-based technique---which provides an explicit prefetch statement at the programming interface. Our quantitative analysis indicates that (static) code-based techniques are a promising alternative to expensive monitoring-based predictors.
