Spack is a package management tool designed to support multiple versions and configurations of software on a wide variety of platforms and environments. It was designed for large supercomputing centers, where many users and application teams share common installations of software on clusters with exotic architectures, using libraries that do not have a standard ABI. Spack is non-destructive: installing a new version does not break existing installations, so many configurations can coexist on the same system. https://github.com/scalability-llnl/spack

Todd is a computer scientist in the Center for Applied ScientificComputing at Lawrence LivermoreNational Laboratory . His research focuses onscalable tools for measuring, analyzing, and visualizing performance theperformance of massively parallel simulations. Todd works closely withproduction simulation teams at LLNL, and he likes to create tools thatusers can pick up easily.

Frustrated with the complexity of building HPC performance tools, Toddstarted developing Spack two years ago to allow users to painlesslyinstall software on big machines. Spack has since been adopted byLivermore Computing, other HPC centers, and LLNL application teams. Theopen source project now includes several core developers at LLNL and arapidly growing community on GitHub. A 1.0 release is coming soon.
