We explore different prefetch distance-degree combinations and very simple, low-cost adaptive policies on a superscalar core with a high bandwidth, high capacity on-chip memory hierarchy. We show that sequential prefetching aggressiveness can be properly tuned at a very low cost to outperform state-of-the-art hardware data prefetchers and complex filtering mechanisms, avoiding performance losses in hostile applications and keeping the pressure of the prefetching on the cache low, turning it out into a real implementation option for current processors. © 2008 Springer-Verlag Berlin Heidelberg.
