| Spack-stack enables the installation of software required | ||
| for HPC system deployments of NOAA's Unified Forecast System (UFS) and | ||
| other weather and climate models, including components of the Joint | ||
| Effort for Data assimilation Integration (JEDI). | ||
|
|
||
| Spack-stack is a collaborative effort between: | ||
| * [NOAA Environmental Modeling Center (EMC)](https://www.emc.ncep.noaa.gov/emc_new.php) | ||
| * [UCAR Joint Center for Satellite Data Assimilation (JCSDA)](https://www.jcsda.org/) | ||
| * [Earth Prediction Innovation Center (EPIC)](https://epic.noaa.gov/). | ||

||
| Spack-stack is a thin layer around a fork of the | ||
| [spack](https://github.com/spack/spack) repository. Spack is a | ||
| community-supported, multi-platform, Python-based package manager | ||
| originally developed by the Lawrence Livermore National Laboratory | ||

|
||
| Spack-stack is a framework for installing software libraries | ||
| to support NOAA's Unified Forecast System (UFS) and the Joint | ||
| Effort for Data assimilation Integration (JEDI) applications on a range of | ||
| R&D and operational platforms. | ||
|
|
||
| Spack-stack 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](https://spack-stack.readthedocs.io/en/latest/PreConfiguredSites.html), and Spack extensions, and uses a fork of the | ||
| [Spack repository](https://github.com/spack/spack). [Spack](https://spack.io/) 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](https://computing.llnl.gov/projects/spack-hpc-package-manager) | ||
| and the [spack | ||
| documentation](https://spack.readthedocs.io/en/latest/). | ||
|
|
||
| The stack can be installed on a range of platforms, from Linux and | ||
| macOS laptops to HPC systems, and comes pre-configured for many | ||
| systems. Users can install the necessary packages for a particular | ||
| application and later add the missing packages for another application | ||
| without having to rebuild the entire stack. | ||
| stable version can be referenced. For more information about Spack, see | ||
| the [LLNL project page for Spack](https://computing.llnl.gov/projects/spack-hpc-package-manager) | ||
| and the [Spack documentation](https://spack.readthedocs.io/en/latest/). | ||
|
|
||
| spack-stack is mainly a collection of Spack configuration files, but | ||
| provides a Spack extension to simplify the installation process: | ||
| **To get started with spack-stack**, either by using an existing | ||
| installation on a [supported platform](https://spack-stack.readthedocs.io/en/latest/PreConfiguredSites.html) or by creating a new installation, see the | ||
| [Getting Started](https://spack-stack.readthedocs.io/en/latest/Overview.html#getting-started) documentation page. | ||
| Full documentation with table of contents can be found at https://spack-stack.readthedocs.io/en/latest/. | ||
|
|
||
| - `spack stack create` is provided to copy common, site-specific, and | ||
| application-specific configuration files into a coherent Spack | ||
| environment and to create container recipes | ||
|
|
||
| - `spack stack setup-meta-modules` creates compiler, MPI and Python | ||
| meta-modules for a convenient setup of a user environment using | ||
| modules (lua and tcl) | ||
|
