Alya multiphysics simulations on Intel’s Xeon Phi accelerators

Abstract

In this paper we describe the porting of Alya, our HPCbased multiphysics simulation code to Intel’s Xeon Phi, assessing code performance. This is a continuation of a short white paper where the solid mechanics module was tested. Here, we add two tests more and asses the code on a much wider context. From the Physical point of view, we solve a complex multiphysics problem (combustion in a kiln furnace) and a single-physics problem with an explicit scheme (compressible flow around a wing). From the architecture point of view, we perform new tests using multiple accelerators on different hosts.
