Spack Stack for the Joint Center for Satellite Data Assimilation

Home News

In 2021, the U.S. Joint Center for Satellite Data Assimilation (JCSDA) and the National Oceanic and Atmospheric Administration’s (NOAA’s) Environmental Modeling Center (EMC) began exploring Spack as an option for creating a single software stack that could be used for both the Joint Effort for Data assimilation Integration (JEDI) software environment and the Unified Forecast System (UFS) ecosystem. Since then both teams have combined their efforts to develop a new stack that works with JEDI, UFS, and other models, eliminating the confusion and upkeep demands of running dozens of different software stacks. The Spack-stack builds seamlessly on Linux and macOS laptops, HPC systems, and cloud platforms. Read more on JCSDA’s blog.
