Computational Evaluation of Cloud HPC with a Global Atmospheric Model

Daniel Arevalo from DeVine Consulting

In this video from the HPC User Forum at Argonne, Daniel Arevalo from DeVine Consulting presents: NAVGEM on the Cloud: Computational Evaluation of Cloud HPC with a Global Atmospheric Model.

Prompted by DoD priorities for modernization, cost savings, and redundancy, this project compared the performance of the NAVGEM on an in-house Cray system against the follow cloud offerings:

  • AWS c4.8xlarge
  • Penguin B30 queue
  • Azure H16r
  • AWS c5n.18xlarge

The Navy Global Environmental Model (NAVGEM) is a global numerical weather prediction computer simulation run by the United States Navy’s Fleet Numerical Meteorology and Oceanography Center. This mathematical model is run four times a day and produces weather forecasts. Along with the NWS’s Global Forecast System, which runs out to 16 days, the ECMWF’s Integrated Forecast System (IFS) and the CMC’s Global Environmental Multiscale Model (GEM), both of which run out 10 days, and the UK Met Office’s Unified Model, which runs out to 7 days, it is one of five synoptic scale medium-range models in general use.”
