Hi, Reading documentation about L2_TRANS: http://software.intel.com/sites/products/documentation/hpc/amplifierxe/en-us/lin/ug_docs/reference/snb/events/l2_trans.html and OFFCORE_REQUESTS: http://software.intel.com/sites/products/documentation/hpc/amplifierxe/en-us/lin/ug_docs/reference/snb/events/offcore_requests.html A distinction is made about L2 hardware prefetches and LLC hardware prefetches. Can someone please explain to me what a LLC hardware prefetch is, how does it differ from an L2 hardware prefetch? All L2 hardware prefetches have to install at least in the L3 because the L3 is inclusive, correct? Is an LLC hardware prefetch a hardware prefetch generated by the L2 but that is only installed into the L3 and not also into the L2? Thanks.. perfwise
