For nearly three years, PESO has stewarded a portfolio of DOE-funded software — including the E4S and Spack ecosystems — improving how tools across the DOE Office of Science are packaged, integrated, tested, documented, and connected across leadership computing facilities. That foundation is directly relevant to Genesis Mission teams standing up new AI-for-science capabilities on a tight timeline, and PESO is eager to work alongside Genesis Mission projects from the outset.
PESO takes a multifaceted approach in the following ways:
Stand up a mission-ready software ecosystem
Package a project's libraries, tools, and dependencies into a coherent, version-compatible environment using E4S and Spack — ready for repeatable science from day one.
Build an integration & assurance lane
Add ecosystem-level continuous integration, compatibility testing, software quality practices, and supply-chain security to catch failures at the seams between products.
De-risk deployment across facilities
Resolve portability issues across leadership systems, accelerators, clusters, cloud-adjacent platforms, and emerging architectures before they slow the science.
Connect AI, simulation & data workflows
Identify interoperability gaps where models, equation-based components, workflows, and data services meet — then coordinate the software teams needed to close them.
Improve the researcher experience
Use shared documentation, usability research, training, and feedback loops to make complex capabilities easier for scientists and engineers to find, adopt, and use well.
Plan for impact that lasts
Apply product stewardship and impact frameworks to clarify users, adoption signals, maintenance needs, and transition paths beyond an initial Genesis milestone — built to grow as AI capabilities, and the software they depend on, keep advancing quickly.
