| Abstract | This presentation was delivered by a student in the Summer Internships in Parallel Computational Science Program (SIParCS) at the National Center for Atmospheric Research (NCAR). SIParCS embeds graduate and undergraduate students as summer interns in NCAR's Computational and Information System Laboratory, offering them significant hands-on R&D opportunities in high performance computing (HPC) and related fields that use HPC for scientific discovery and modeling. Performance models are extremely useful in predicting run time performance for applications on new platforms, including those that do not currently exist. In this work, we build and compare empirical and analytical performance models of GHOST (Geophysical High Order Suite for Turbulence), which is a hybrid MPI - OpenMP solution that parallelizes computations carried out in the pseudo-spectral methods for fluid turbulence. |
