Estimating the Effect of Cache Misses on the Performance of Parallel Applications Using Analytical Models
In this paper a methodology to characterize the influence of cache misses on the performance of parallel applications is presented. This methodology is based on the TIA framework to obtain analytical models of given observable quantities by instrumenting the source code and applying model selection techniques. In particular, two metrics related with the performance are considered in this work: the number of cache misses and the elapsed time. Based on both models, the influence in terms of execution time due to the cache misses can be inferred. Two different versions of the parallel product of dense matrices are used as case of study.
