Bridging the Architecture Gap: Abstracting Performance-Relevant Properties of Modern Server Processors
Johannes Hofmann, Christie L. Alappat, Georg Hager +2
We describe a universal modeling approach for predicting single- and multicore runtime of steady-state loops on server processors. To this end we strictly differentiate between app…
