SGI Technology Guide for ANSYS Fluent Analysts - Application Brief

ANSYS Fluent software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications ranging from air flow over an aircraft wing to combustion in a furnace, from blood flow to semiconductor manufacturing, and from clean room design to wastewater treatment plants. Special models that give the software the ability to model in-cylinder combustion, aero acoustics, turbo machinery, and multiphase systems have served to broaden its reach. ANSYS Fluent solutions provide volume parallel capabilities to support multiple users, with complete flexibility to deploy and use the software wherever there are distributed resources. Nevertheless, execution of solutions requires extreme care in allocating hardware resources. The topic is even more important given hardware variety today, ranging from single node multi-core workstations through clusters with multiple nodes to single image many-core systems addressing very large memory space. This paper will explore MPI performance, core frequency, choice of a network topology, memory speed and use of hyper-threading of such solutions to establish guidelines for running ANSYS Fluent on advanced SGI computer hardware systems.
