Project Description
The E4S project [https://e4s.io] builds ECP Software Technology (ST) products in a curated, well-tested distribution of containerized and bare-metal builds of packages. It uses Spack [https://spack.io] as the underlying package manager for building the tools and numerical libraries. It supports Singularity and Shifter container runtimes. E4S aims to create a Spack build cache of ST products available for download when a user installs packages with complex package dependency graphs.
