Sustaining DOE's HPC Software
August 4, 2026 — PESO's DAV and TOOLS Integrations provide shared continuous-integration, packaging, and security-hardening infrastructure for widely used data-analysis, visualization, and performance-tools packages, including ADIOS2, HDF5, ParaView, and HPCToolkit. Recent work helped ADIOS2 raise its OpenSSF Scorecard from 7.1 to 8.6 and pass the OpenSSF Best Practices Badge, with new security policies extended to several other packages. This work is done in coordination with RAPIDS, STEP, E4S, FASTMath, and DOE facility partners, so improvements can reach users through E4S rather than being repeated separately by each product team.
