Hera more than doubles the previous Theia system with a total capacity of 3,270 trillion floating point operations per second – or 3.27 petaflops. It is Cray System and provides compute capacity of 45 million hours per month with 63,840 cores and a total scratch disk capacity of 18.5 Petabytes.

Hera supports development of weather modeling across Office of Oceanic and Atmospheric Research and National Weather Service to improve the prediction of high-impact weather events and evaluate potential future directions for models and data assimilation

NOAA’s RDHPCS also provides software engineering support and associated tools to re-architect NOAA’s applications to run efficiently on next generation fine-grain HPC architectures. The Fine Grain Graphical Processing Units with a total capacity of 2,000 trillion floating point operations per second - or 2.0 petaflops provide an experimental test bed for application development of next-generation research computing technologies, but also help NOAA to more efficiently use its existing high performance computing assets.

Image is of the NOAA Hera supercomputer located in Fairmont, WV. Hera has 52,640 Skylake processors with multiple grey cabinets (20 are shown in the image) and is labeled with CRAY CS500. The racks of hardware components are stacked vertically to save space,  allow for ease of connecting the many nodes and cores of the supercomputer, and improve efficiency in cooling.
