Abstract

<p>Intel's Xeon Phi processors have attracted considerable attention as promising many-core processors for scientific computing and simulation. We report the performance results of parallelized DFT calculations with the SMASH program on a first-generation chip (Knights Corner) in a native mode of executions. As a result, an acceleration of 1.4 was observed for a multi-threading increment from 60 cores to 120 cores. This fact implies a preferable performance on the second-generation Phi (Knights Landing) processors.</p>
