The modern scientific software stack includes thousands of packages, from C, C++, and Fortran libraries, to packages written in interpreted languages like Python and R. HPC applications may depend on hundreds of packages spanning all of these ecosystems. To achieve high performance, they must also leverage low-level and difficult-to-build libraries such as MPI, BLAS, and LAPACK. Integrating this stack is extremely challenging. The complexity can be an obstacle to deployment at HPC sites and deters developers from building on each other’s work.
Spack is an open source tool for HPC package management that simplifies building, installing, customizing, and sharing HPC software stacks. In the past few years, its adoption has grown rapidly: by end-users, by HPC developers, and by the world’s largest HPC centers. Spack provides a powerful and flexible dependency model, a simple Python syntax for writing package build recipes, and a repository of over 5,000 community-maintained packages. This tutorial provides a thorough introduction to Spack’s capabilities: installing and authoring packages, integrating Spack with development workflows, and using Spack for deployment at HPC facilities. Attendees will learn foundational skills for automating day-to-day tasks, as well as deeper knowledge of Spack for advanced use cases.
