Abstract

A technique for data prefetching for a multi-core chip includes determining memory utilization of the multi-core chip. In response to the memory utilization of the multi-core chip exceeding a first level, data prefetching for the multi-core chip is modified from a first data prefetching arrangement to a second data prefetching arrangement to minimize unused prefetched cache lines. In response to the memory utilization of the multi-core chip not exceeding the first level, the first data prefetching arrangement is maintained. The first and second data prefetching arrangements are different.
