Chapter 6

HPC Benchmarks for CFD

Abstract

This chapter is about the use of high-performance computing in computational flow dynamics, a real devourer of resources. Various types of comparative studies are analyzed in detail and commented on in terms of interconnectivity, storage, and memory requirements. The ANSYS® Fluent®, CFX®, and OpenFOAM benchmarks provide an overview of the nature of problems run on the various types of hardware.
