Making software ecosystems first-class citizens

The focus area leads of the U.S. Department of Energy Exascale Computing Project (ECP) have written an article in the online journal Nature Computational Science in which they advocate a new approach to software development in emerging exascale systems.

Central to the new approach is the concept of community software ecosystems. To work toward a sustainable path for next-generation computational science, the authors argue that community software ecosystem perspectives are needed — recognizing the vital role of software, not as just a byproduct of research on new algorithms or domain-specific science, but as an essential first-class citizen.”  The authors advocate that all member of the computational science community can play important roles in catalyzing change in projects, institutions and communities to address the technical, cognitive and social challenges of scientific software.

The authors lead ECP focus areas: Software Technology, Application Development, Hardware and Integration. The full paper presenting their discussion is available on the web:
