Improving Weather and Climate Research

Critical high-performance computing systems support the NOAA community in conducting research and development for environmental science. GDIT HPC services and systems integration support 430 PB of user data for weather, seasonal and climate model predictions. Our latest upgrade to NOAA Hera led the supercomputer to be ranked 88 fastest in the world in 2020.

Supercomputer Upgrade Speeds Biomedical Research

GDIT upgraded the National Institutes of Health (NIH) Biowulf, the largest HPC cluster dedicated to biomedical research, to be ranked 66th fastest in the world in 2017. Our hardware solution seamlessly integrates with existing hardware and software and our team provides daily administration and program support. Biowulf is also instrumental for research into new treatments for diseases, including coronaviruses.
