https://community.intel.com/t5/Software-Tuning-Performance/Attributing-lost-cycles-to-cache-misses-and-mis/m-p/1104287#M5917 <P>Is there a way to identify between two code execution points, like for example start and end of a program how many cycles were impacted because of cache misses and branch mispredicts.</P> <P>I want to understand if the number is meaningful for my application. My application finishes a performance sensitive task in 100ms and I want to know if the total impact of missed caches and mispredicts even comes to let's say 10ms.</P> Tue, 21 Jun 2016 18:26:10 GMT Hayden_L_ 2016-06-21T18:26:10Z https://community.intel.com/t5/Software-Tuning-Performance/Attributing-lost-cycles-to-cache-misses-and-mis/m-p/1104287#M5917 <P>Is there a way to identify between two code execution points, like for example start and end of a program how many cycles were impacted because of cache misses and branch mispredicts.</P> <P>I want to understand if the number is meaningful for my application.

Is there an equivalent for L1D and L2 cache misses also I couldn't find one .. maybe I have to construct one using the ones available, and any help here is appreciated.</P> Tue, 21 Jun 2016 18:30:55 GMT https://community.intel.com/t5/Software-Tuning-Performance/Attributing-lost-cycles-to-cache-misses-and-mis/m-p/1104288#M5918 Hayden_L_ 2016-06-21T18:30:55Z
