Interactive Exploratory Graph-Enabled Data Analytics at High-Performance Computing Scales

Roger Pearce | 21-ERD-020

Executive Summary

We will develop a next-generation high-performance computing data analytics system to enable interactive hybrid graph and data analytics. If successful, this system will be able to analyze research problems relevant to national missions such as space security and cybersecurity at a scale much larger than the current state of the art.
