At its' core, this paper is describing the use of cloud computing as an alternative to onsite high-performance computing (HPC). At 'scale' is a loaded term in HPC. This paper examines performance improvements in public cloud offerings and compares small runs in the cloud versus a six-year-old onsite HPC system. However, an MPI performance test up to 8 nodes, a mini-application performance tests up to 8 nodes, and a computational fluid dynamics domain science examination of 2 nodes does not adequately explore scaling.
