Spack-stack is a framework for installing software libraries to support a wide range of numerical weather prediction and data assimilation systems developed by the spack-stack project partners.
Spack-stack supports installations on a range of R&D and operational platforms. It provides a set of installation templates (package lists), default package settings, system configurations for a range of platforms, spack extensions, and uses forks of the spack and spack-packages repositories.
Spack is a community-supported, multi-platform package manager developed by Lawrence Livermore National Laboratory (LLNL). Spack is provided as a submodule to spack-stack so that a stable version can be referenced. For more information about spack, see the LLNL project page and the spack documentation.
Spack-stack is a collaborative effort between:
- NOAA Environmental Modeling Center (EMC)
- UCAR Joint Center for Satellite Data Assimilation (JCSDA)
- Earth Prediction Innovation Center (EPIC)
- U.S. Naval Research Laboratory (NRL)
- NASA Global Modeling and Assimilation Office (GMAO)
For more information about the organization of the spack-stack project, see the Project Charter.
The documentation is organized into different sections targeting end users, advanced users, and developers of spack-stack.
End users who wish to build software with existing spack-stack installatons on fully-supported (tier-1) platforms should consult the End user docs linked below. Advanced users who wish to deploy spack-stack on other systems, as well as developers of spack-stack, should consult the Developers and advanced user docs linked below.
