Spack-stack is a framework for installing software libraries to support NOAA's Unified Forecast System (UFS) applications and the Joint Effort for Data assimilation Integration (JEDI) coupled to several Earth system prediction models (MPAS, NEPTUNE, UM, FV3, GEOS, UFS).
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 macOS and Linux workstation, HPC, and cloud platforms, and Spack extensions, and uses a fork of the Spack repository. 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 for Spack and the Spack documentation.
To get started with spack-stack, either by using an existing installation on a supported platform or by creating a new installation, see the Getting Started documentation page. Full documentation with table of contents can be found at https://spack-stack.readthedocs.io/en/latest/.
Spack-stack is a collaborative effort between:
- NOAA Environmental Modeling Center (EMC): Alex Richert, Hang Lei, Ed Hartnett
