Abstract
A last-level collective hardware prefetcher (LLCHP) is described. The LLCHP is to detect a first off-chip memory access request by a first processor core of a plurality of processor cores. The LLCHP is further to determine, based on the first off-chip memory access request, that first data associated with the first off-chip memory access request is associated with second data of a second processor core of the plurality of processor cores. The LLCHP is further to prefetch the first data and the second data based on the determination.
