Will HSD and OHD be up to the task? Need focused discussion and possibly white paper to refine what to ask of OCWWS Need focused discussion and possibly white paper to refine what to ask of OCWWS Deltares is crafting a draft plan as part of the CHPS contract Deltares is crafting a draft plan as part of the CHPS contract

8 July 2009CHPS Status and Activities7 News from June Workshop  Mean areal temperature problems Will grids work in the mountains? Will grids work in the mountains? We don’t know how calibration and operational MATs differ today We don’t know how calibration and operational MATs differ today NWRFC uses lots of temperature mods; indicative of problems NWRFC uses lots of temperature mods; indicative of problems Need a rigorous comparison at some RFCs focused on model output not temperature output (OHD science work needed?) Need a rigorous comparison at some RFCs focused on model output not temperature output (OHD science work needed?)  Post BOC leadership CAT (as we know it) is not sustainable; too much work CAT (as we know it) is not sustainable; too much work Similar HIC-based committee at a lower level of engagement could follow the CAT Similar HIC-based committee at a lower level of engagement could follow the CAT How might the AHPS budget process evolve as AHPS ends? How might the AHPS budget process evolve as AHPS ends? DSST has not worked out as well as hoped DSST has not worked out as well as hoped

8 July 2009CHPS Status and Activities8 System Performance  Challenge Flexibility, adaptability, and maintainability require loosely coupled service-based architecture Flexibility, adaptability, and maintainability require loosely coupled service-based architecture Loosely coupled service-based architecture takes more computer resources than tightly coupled, monolithic, and highly optimized architecture (i.e., “there’s no free lunch”) Loosely coupled service-based architecture takes more computer resources than tightly coupled, monolithic, and highly optimized architecture (i.e., “there’s no free lunch”)

8 July 2009CHPS Status and Activities9 System Performance  Expectations Java can be a slower executing computational language than Fortran (e.g., our SAC-HT exp.) yet far more programmer productive Java can be a slower executing computational language than Fortran (e.g., our SAC-HT exp.) yet far more programmer productive “Wrapped” Fortran models, to execute within CHPS infrastructure, will be slower than within NWSRFS “Wrapped” Fortran models, to execute within CHPS infrastructure, will be slower than within NWSRFS However, a “wrapped” Fortran model is slower than its corresponding Java translation However, a “wrapped” Fortran model is slower than its corresponding Java translation CHPS will require more raw computer resources than NWSRFS to accomplish similar atomic tasks CHPS will require more raw computer resources than NWSRFS to accomplish similar atomic tasks

8 July 2009CHPS Status and Activities10 System Performance  Approaches Get functionality right first, then optimize Get functionality right first, then optimize Introduce CHPS-specific hardware for migration and parallel operations at RFCs Introduce CHPS-specific hardware for migration and parallel operations at RFCs Establish acceptable performance criteria with RFCs realizing challenges and expectations Establish acceptable performance criteria with RFCs realizing challenges and expectations Changes in RFC forecaster operating procedures may impact performance needs Changes in RFC forecaster operating procedures may impact performance needs Displays & model execution is separatedDisplays & model execution is separated More opportunity for forecaster to multi-taskMore opportunity for forecaster to multi-task

8 July 2009CHPS Status and Activities11 System Performance  Approaches (cont’d) Creation and prosecution of “CHPS Performance Testing Plan” by Deltares covering all aspects of forecaster interaction Creation and prosecution of “CHPS Performance Testing Plan” by Deltares covering all aspects of forecaster interaction ESP-type model performance benchmarks now underway ESP-type model performance benchmarks now underway Deltares-OHD tiger team in action since May with weekly telephone conferences Deltares-OHD tiger team in action since May with weekly telephone conferences Deltares & OHD using “YourKit” Java profiler Deltares & OHD using “YourKit” Java profiler Benchmarks to be run at CAT site(s) Benchmarks to be run at CAT site(s)
