The High-Performance Software Foundation (HPSF) received the 2025 HPCwire Readers’ Choice Award for Best HPC Collaboration, recognizing the collective achievement of HPSF’s member institutions in promoting sustainable, open, and collaborative scientific software ecosystems. Lawrence Berkeley National Laboratory (Berkeley Lab), which contributes vital projects and leadership to HPSF, played a key role in the collaboration honored by this award.

Even before becoming an institutional member in early 2025, the Lab was already a key part of HPSF’s core collaborative efforts, contributing two flagship scientific software projects: WarpX from the Accelerator Technology & Applied Physics (ATAP) Division and AMReX from the Applied Mathematics & Computational Research (AMCR) Division. Researchers from these teams have provided technical leadership, contributed to governance, and actively promoted best practices for scientific software development.

Berkeley Lab’s representation within HPSF includes Andrew Myers (AMReX, AMCR) and Axel Huebl (WarpX, ATAP), who serve on the HPSF Technical Advisory Council (TAC). Huebl also acts as the elected TAC representative to the Foundation’s Governing Board.

HPSF, founded in 2024 under the Linux Foundation, aims to advance the development, sustainability, and adoption of open, high-performance scientific software. Berkeley Lab exemplifies this goal not only through its project contributions but also through its advocacy for community-driven, portable, and sustainable software ecosystems.

A notable example of Berkeley Lab’s broader impact is the National Energy Research Scientific Computing Center (NERSC), a Department of Energy Office of Science user facility at the Lab. NERSC staff leverage and contribute to HPSF-supported projects, including Kokkos, OpenCHAMI, and Spack, and bring these advances to production at scale. Through these direct contributions, NERSC is strengthening infrastructure for more than 12,000 HPC and AI users, improving performance benchmarking, regression testing, and workflow reliability, and setting new standards for large-scale scientific computing.

By guiding HPSF’s direction and fostering open collaboration, Berkeley Lab and its partners are helping to build a more robust and sustainable scientific software ecosystem—not only for their own researchers, but for the global computational science community.

“Joining forces through HPSF allows us to share expertise and approaches with a global community. By collaborating openly, we ensure the scientific software we develop at Berkeley Lab can be sustained, improved, and adopted by researchers across disciplines,” said Myers, a lead developer of AMReX and member of the HPSF Technical Advisory Council. “This award demonstrates what we can achieve when institutions work together to support advanced computing.”

“HPSF allows open-source scientific software to thrive through collective stewardship and technical excellence,” said Huebl, a lead developer of WarpX and member of the HPSF Governing Board. “At Berkeley Lab, it’s exciting to see our community contributing foundational tools and practices—and this recognition shows the real impact of our shared commitment to sustainability and collaboration.”
