What's the performance counter of how many AVX instructions executed on Haswell processor
I read the latest SDM which published in this September, but I couldn't find the description of the performance counter about the AVX on Haswell. So I could not get the number from PMU too. Any knows this? Thanks in advance :)
It appears that there are no documented counters for AVX events in the Haswell products.
It is possible that event 0x11 (SIMD_FP_256) is still implemented in Haswell (I have not checked), but this event over-counts so badly that it is not very useful. This is discussed in a number of other forum threads, e.g., https://software.intel.com/en-us/forums/topic/499193
