PESO exists to sustain and advance a robust, versatile, and portable HPC-AI software ecosystem and support the community of people who make that ecosystem effective. PESO sponsors the Software Ecosystem for Science (E4S) and the Spack package management system for open science. PESO contributes to community engagement through the Consortium for the Advancement of Scientific Software (CASS), the Better Scientific Software (BSSW) website and Fellowship program, and the High Performance Software Foundation (HPSF).

Stakeholder engagement across the CASS consortium, computing facilities, commercial HPC companies, US agencies, and industrial users — plus community development through the Better Scientific Software (BSSw) Fellowship Program and workforce initiatives.
Integration partnerships — Spack integration, CI testing, portfolio support and management, collaboration with software stewardship organizations — plus software quality assurance and security: supply chain, product quality, testing, and documentation.
E4S and Spack integration, features, documentation, and training; the Frank test & development platform plus cloud resources; and BSSw.io articles on scientific software productivity and sustainability.
Technical and community benefits, at every scale. Read more on Engage →
