Software Platform

Velo is a reusable, domain-independent, eScience environment and knowledge management infrastructure for modeling and simulation. It leverages, integrates, and extends web-based, open-source collaborative and data management technologies to create a scalable core platform tailored to specific science domains. Velo also orchestrates complex workflows so common functions can be developed as reusable components generic to any workflows.

The complexity, computational demands, and need for flexibility in the PRIMA framework requires a powerful and nimble software framework. For many applications, this need is met by Velo, a software infrastructure designed at PNNL for defining and orchestrating workflows and managing projects, content, and metadata.
