I would guess that the paper is talking about entries the top level cache (L2 or L3depending on processor generation) that is shared between cores. Here, there are certain patterns you need to be aware of to make sure you are using cache effectively and not causing yourself performance headaches.<BR /><BR />You can check Chapter 11 in the Intel Architecture Software Developer's Manual, vol 3A for more information about how caching works. <A href="http://www.intel.com/Assets/PDF/manual/253668.pdf">http://www.intel.com/Assets/PDF/manual/253668.pdf</A><BR /><BR /> Fri, 06 Aug 2010 18:47:33 GMT https://community.intel.com/t5/Intel-Moderncode-for-Parallel/what-elements-does-cache-entry-contain-in-cache/m-p/767457#M81 Anthony_B_Intel 2010-08-06T18:47:33Z what elements does cache entry contain in cache? https://community.intel.com/t5/Intel-Moderncode-for-Parallel/what-elements-does-cache-entry-contain-in-cache/m-p/767458#M82 Thank you, asbock.<BR />Your reply is perfect.
