Weather Research & Forecasting Model Xabriel J Collazo-Mojica Alex Orta Michael McFail Javier Figueroa
Presentation Overview • Research Motivation • Current Project Status • WRF Documentation Draft • WRF Benchmarking Status/Process • WRF Profiling Status • Hurricane Mitigation Wiki Website • Pending Goals • Summary
Motivation • Lack of documentation of the WRF code, producing unknown knowledge of the code’s functionality • Need of more computing power to calculate higher resolution weather forecasts • Need to understand WRF internal behavior in GRID environment for future improvement
Challenges • Accomplished: • WRF Documentation First Draft • WRF Benchmarking Started • WRF Profiler Evaluation First Draft • To be accomplished: • Finish Documentation (Final Draft) • Finish Benchmarking and create paper about results • Finish Profiler Evaluation • Populate “Hurricane Mitigation Wiki Page”
WRF Documentation • Finished WRF Documentation First Draft • PDF Overview • WRF Documentation in Google • Future effort to make it a formal Document • Help future developer community • Get input from Community • John Michalakes
WRF Benchmarking • Finished Benchmarking GCB • Continued effort to generate a Mathematical Model for WRF behavior • Preparation for Benchmarking University Of North Florida, 32 node, 128 CPUs cluster
Benchmark UNF’s cluster • 32 node – 128 CPUs cluster • If we use the same input we can compare to GCB’s. • More nodes = More data • Is our current equation even close?
WRF Profiling • Final set of criteria to evaluate profiler tools • Final Profilers • TAU • SvPablo • Paraver • IBM HPC Toolkit • PGI-CDK • The profiler that best fit WRF will be profiling the program
Profiler Evaluation Criteria • More information in the Google Document • Profiler evaluation criteria example: SvPablo TAU
Goals • Produce final draft of WRF Documentation • Benchmarking WRF in bigger environments • Come up with a Mathematical equation to model WRF behavior • Finish profiler evaluation • Use profiler on WRF
Summary • Finished the WRF Documentation Draft • Finished Benchmarking GCB cluster • Gained research experience on graduate student projects • Obtained great knowledge on High Performance Computing, FORTRAN and parallel computing
