4. Trends: Within TeraGrid and successor XSEDE, the Number of Research Projects, Institutions and Users have increased

5. While the number of resources has decreased, actual core hours increased but requests remain 2-5x available

6. All Scientific Disciplines have increased use of resources

7. As the resources increase, benefits are broadly distributed (green line) beyond the top 20 users (colored lines)

8. Use of all resources/services, including XSEDE, Blue Waters and NCAR are well characterized Additional Trend Analysis beginning: – Modest increases in parallelism (number of cores used) and job size – Emerging scientific/workflow/data analytic trends? – Industry? – Full costs highly competitive Complement with community engagements in the context of all five strategies: – Foundational research to fully exploit parallelism and concurrency…. – Applications research and development…. – Building, testing, and deploying both sustainable and innovative resources into a collaboration ecosystem…. – Comprehensive education and workforce programs… – Development and evaluation of transformational and grand challenge community programs…
