Abstract
Official abstract text for this publication.
The disclosed embodiments relate to a method for dynamically changing a prefetching configuration in a computer system, wherein the prefetching configuration specifies how to change an ahead distance that specifies how many references ahead to prefetch for each stream. During operation of the computer system, the method keeps track of one or more stream lengths, wherein a stream is a sequence of memory references with a constant stride. Next, the method dynamically changes the prefetching configuration for the computer system based on observed stream lengths in a most-recent window of time.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for dynamically changing a prefetching configuration in a computer system that supports multiple prefetching configurations, comprising: during operation of the computer system, keeping track of stream lengths of two or more streams, wherein the keeping track involves maintaining, for each stream of the two or more streams, a hit counter for the stream that counts a number of demand hits for prefetches generated according to a given prefetching conf…
