Todd Gamblin is a computer scientist in the Center for Applied Scientific Computing at Lawrence Livermore National Laboratory (LLNL). His research focuses on scalable tools for measuring, analyzing, and visualizing parallel performance data. He leads LLNL’s DevRAMP (Reproducibility, Analysis, Monitoring, and Performance) team, and he is the creator of Spack, the deployment tool for the Exascale Computing Project’s (ECP) software stack. In high-performance computing, developers build software from source code and optimize it for the targeted computer’s architecture. 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.
