HPCwire magazine selected the Spack project for the 2023 Editor’s Choice Award for Best High-Performance Computing (HPC) Programming Tool or Technology. Spack, which was created in 2013, is a package manager for HPC that is recognized as the official deployment tool for the Department of Energy’s Exascale Computing Project. Livermore core team members include team lead Todd Gamblin and developers Gregory Becker, Tamara Dahlgren, Peter Scheibel, Richarda Butler, and Alec Scott. Spack was used on the first exascale machines at Argonne and Oak Ridge laboratories and will also be used on Livermore’s El Capitan system.
Livermore’s Simple Cloud Resolving E3SM Atmosphere Model (SCREAM) team has been awarded the first-ever Association for Computing Machinery Gordon Bell Prize for Climate Modelling. SCREAM is a global cloud-resolving climate model that is the first to run on an exascale computer and to break the one-simulated-year-per-day barrier for realistic cloud-resolving simulations at less than five kilometers of horizontal resolution. Running on Oak Ridge National Laboratory’s Frontier supercomputer, SCREAM achieves 1.26 simulated years per day, an unparalleled capability for addressing climate change.
Livermore computer scientist Johannes Doerfert has been presented with the Institute of Electrical and Electronics Engineers Computer Society’s Technical Community on High Performance Computing Early Career Researchers Award for Excellence in High Performance Computing. This award recognizes individuals within five years of completing their Ph.D. for their outstanding contributions to the field of high-performance computing. Doerfert has contributed to three subprojects within the Exascale Computing Project, as well as the open source LLVM compiler framework, for which he uses his expertise in compiling and OpenMP, a multiplatform, shared-memory parallel programming tool.
Livermore physicist Annie Kritcher has been named to Nature’s 10, which recognizes 10 people who helped shape science in 2023, for her role as principal designer for the fusion experiment at the National Ignition Facility that achieved fusion ignition. Since the initial ignition achievement in December of 2022, Kritcher and the Inertial Confinement Fusion team have replicated the result three times, paving the way for future shots with higher yields and greater robustness to enable new experiments for stockpile stewardship.
