By increasing adoption, aiding community growth, and enabling development efforts, HPSF supports projects that advance portable software for diverse hardware. HPSF is lowering barriers to productive use of today’s and future high performance computing systems.
Andy Warner is a Distinguished Technologist at Hewlett-Packard Enterprise. He is HPE’s chief systems architect for HPC, and he has been active in a number of large HPC deployments, including Astra, the first large-scale ARM supercomputer, deployed at Sandia National Laboratories, the Frontier system at Oak Ridge National Laboratory, and LLNL’s upcoming El Capitan supercomputer. Andy leads the packaging working group as part of the CORAL2 collaboration that led to the last two of these systems, and he has been a long-time advocate for using open source solutions and open collaboration as a means to meet customer needs. Andy is HPE’s representative on the governing board of the High Performance Software Foundation.
Brendan Bouffler has decades of experience in the tech industry, building large-scale HPC systems for R&D organizations globally – working in North America, Asia, and Europe. After leading the HPC business in Asia for a hardware maker, Brendan joined Amazon in 2014 when it became clear to him that cloud would become the exceptional computing tool the global R&D community needed to bring forward the discoveries that would change the world for us all. He’s a board member for the High Performance Software Foundation (HPSF), supporting open-source projects which ensure democratic access to critical datasets, tools, and techniques. He holds a degree in Physics and an interest in testing several of its laws as they apply to bicycles. This has frequently resulted in hospitalization. He is based in London.
Christian Trott is a high performance computing expert with extensive experience in designing and implementing software for modern HPC systems. He is a principal member of staff at Sandia National Laboratories, where he co-leads the Kokkos core team developing performance portability solutions for engineering and science applications. Christian is also the head of Sandia’s delegation to the ISO C++ standards committee, and a principal author of C++ standard features such as mdspan and linear algebra support. He also serves as adviser to numerous application teams, helping them redesign their codes using Kokkos and achieve performance portability for the next generation of supercomputers.
In the past, Christian contributed significantly to numerous scientific software projects such as Trilinos and LAMMPS. He earned a doctorate in theoretical physics with a focus on computational material research from the Ilmenau University of Technology in Germany.
Damien Lebrun-Grandie is a Computational Scientist with Oak Ridge National Laboratory. His research is focused on the development of algorithms and enabling technologies for the solution of large-scale complex engineering and scientific problems. He is a high-performance computing expert and is a member of the ISO C++ Standards Committee. He co-leads the Kokkos performance portability library team. He holds an MEng in applied physics from Grenoble INP in France, and an MSc in physics from Karlsruhe Institute of Technology in Germany. He completed his PhD in nuclear engineering at Texas A&M University.
Julien Bigot holds a PhD in computer science and works as a permanent CEA Research Scientist at Maison de la Simulation. His main research interest is related to programming models for HPC applications. He focuses on separation of concerns between performance optimization and semantics, both for algorithm expression and data analytics. He co-leads Exa-DoST, the project of NumPEx building the French data-oriented Exascale software stack. He also leads CExA, the project of the CEA to contribute to Kokkos and port applications to GPU based on this.
Todd Gamblin is a Distinguished Member of Technical Staff at Lawrence Livermore National Laboratory (LLNL). He created Spack (spack.io), a widely used open-source package manager for high performance computing, partially sustained by the PESO project. He is a co-founder of the High Performance Software Foundation (hpsf.io). At LLNL, he works on software and future computing strategy in the Advanced Technology Office in LLNL’s Livermore Computing division, and he leads a number of research and development projects focused on software integration.
