1. WRF - REU Project Presentation Michael McFail Xabriel J Collazo-Mojica Javier Figueroa Alex Orta

2. Presentation Outline  Motivation  Final Draft Tutorial  Benchmark Status  Automatic Benchmarking  Mathematical Model  Profiling Status  Wiki Website Status  Summary

3. Motivation  Lack of documentation of the WRF code  Need to understand how WRF functions  Need more computing power to calculate higher resolution weather forecasts  Need to understand WRF’s internal behavior in grid environment for future improvement

4. WRF Documentation - Final Draft  Final layout of document is finished  No further changes to graphs  Fixed examples for better understanding  Added suggested sections and comments from team  Future effort to base a technical paper on this documentation  Waiting on John’s input

5. Benchmarking Status  Automatic Benchmarking  Results from runs on GCB  Graphs  Mathematical Model  Explanation on what we found so far

6. Benchmarking Status - Results

7. Benchmarking Status - Results (Cont)‏ 1179.7583333 2108.7 378.55833333 463.41666667 554.21666667 650.71666667 744.30833333 843.66666667

8. Benchmarking Status - Mathematical Model  Product of Sum: (Assumption)‏ Number of nodes in parallel execution Static resource parameters

9. Benchmarking Status - Future Work  Two ways to go:  Try to see if Raju's new equation is a viable choice (treat code as black box)‏  Finally profile WRF code and make an application-specific model  Anyway, we need a bigger cluster environment

10. Profiling Status  Profiling document  Only TAU and SvPablo work  TAU almost ready to use with WRF  For others, problems documented

11. Wiki Hurricane Mitigation  Keep an archive of related knowledge  Posted papers we have read  Posted reviews of papers  Drafted wiki site redesign  Easier navigation

12. Summary  Finished WRF Documentation  Finished benchmarks of WRF in GCB cluster  Finished profilers documentation for future profiling  Gained valuable experience in high performance computing and CS research
