Abstract

This work is devoted to evaluating the performance of a multicore CPU Elbrus-8C processor in supercomputer computational fluid dynamics (CFD) applications. Parallel simulation codes based on highly accurate methods on unstructured meshes for modeling the turbulent flows are considered. The main features of the Elbrus architecture are described, and the approaches for adaptating and optimizing the computing software are presented. The performance is investigated for both entire algorithms and their operations separately. The results of comparative testing with different multicore Intel and AMD CPUs are presented.
