NERSC has partnered with over 20 representative application developer teams to evaluate and optimize their workloads on the Intel XeonPhi Knights Landing processor. In this paper, we present a summary of this two year effort and will present the lessons we learned in that process. We analyze the overall performance improvements of these codes quantifying impacts of bothXeonPhi architectural features as well as code optimization on application performance. We show average application speedups of greater than 3 on KNL and KNL vs Haswell node performance advantage across the applications.
