Webb11 mars 2012 · The URL you reference is for core architecture and E5520 processor is Nehalem-based architecture. Usually you can enable/disable the prefetchers using the BIOS boot options. Look for something in the BIOS labeled hardware prefetch (probably under the CPU-related section of the BIOS screens). Hope this helps, Pat. Webbspecialized hardware units dedicated to the task of fetching in new data. Part of the gap can even be eliminated with sophisticated programmer- and compiler-directed software-prefetching mechanisms [2, 4, 30, 41]. More ideal is a pure-microarchitecture technique that can do the same: achieving high performance for memory-latency-
