Description
Many HPC, tightly-coupled workloads scale linearly on AWS in the Gustafson-Barsis sense. This presentation will discuss some large CFD calculations (400M cells and more). The ability to tailor the architecture to the application allows these applications to run at speeds similar, and sometimes faster, to on-prem facilities. In particular scaling of the openFOAM (simpleFoam) will be explored, including where various limits are reached for several architectures. Strategies that allowed us to work around these limits will be presented.
