Audio/Video: Spotlight on Spack

HPC developers build software from source code and optimize it for the targeted computer’s architecture. LLNL-developed Spack handles the process of downloading a tool and all the necessary dependencies – which can be tens or hundreds of other packages – and assembles those components and ensures they are properly linked and optimized for the machine. Todd Gamblin, Spack’s lead developer, talks with the Exascale Computing Project’s Exascale podcast. Both audio and video versions are available. Total runtime is 13:54.
