[Excerpt] This work examines the parallel scalability characteristics of commercial CFD software FLUENT and STAR-CD for up to 256 processing cores, and research CFD software CDP from Stanford University for up to 512 cores – for transient CFD simulations that heavy in IO relative to numerical operations. In three independent studies conducted with engineering contributions from the University of Cambridge, Intel, SGI, and Panasas, each Linux HPC environment combined Intel Xeon clusters with a Panasas parallel file system and shared storage. The motivation for these studies was to quantify the performance and scalability benefits of parallel IO in CFD software on a parallel file system (PanFS) verses a conventional serial NFS file system for a variety of transient CFD cases.
