Abstract

The IBM POWER8 CPU is a high-performance multi-core hardware which targets the usage with computational intense numerical codes. Combustion modeling is among the most computational demanding mathematical problems. Therefore, in this paper we present a performance analysis of the 3D-combustion modeling software RECOM-AIOLOS on a POWER8 node. The analysis reveals the strengths of the POWER8 hardware being a NUMA system, but also the importance of a proper memory allocation when using OpenMP or a hybrid (OpenMP + MPI) parallelization approach on such a system.
