The Pangeo Ecosystem: Interactive Computing Tools for the Geosciences: Benchmarking on HPC.

The Pangeo ecosystem is an interactive computing software stack for HPC and public cloud infrastructures. In this paper, we show benchmarking results of the Pangeo platform on two different HPC systems. Four different geoscience operations were considered in this benchmarking study with varying chunk sizes and chunking schemes. Both strong and weak scaling analyses were performed. Chunk sizes between 64 MB to 512 MB were considered, with the best scalability obtained for 512 MB. Compared to certain manual chunking schemes, the auto chunking scheme scaled well.
