SEE-GRID-SCI WRF – ARW application: Overview www. see-grid-sci. eu PSC 03, 15. -16. January 2009, Bucharest Davor Davidovic Rudjer Boskovic Institute Zagreb, Croatia The SEE-GRID-SCI initiative is co-funded by the European Commission under the FP 7 Research Infrastructures contract no. 211338

WRF-ARWPartners partners Partners involved in WRF-ARW grid deployment § Rudjer Boskovic Institute (RBI) § Department of Geophysics University of Zagreb, Croatia (AMGI) § Faculty of Graphical Art of the University of Zagreb, Croatia (FGA) § University of Banja Luka, Faculty of Electrical Engineering (Uo. BL) § Federal Hydro-Meteorological Institute, Sarajevo, Bi. H (FHMI) § Hydro-meteorological Institute of Republic of Srpska, Bi. H (RHMI) § Georgian Research and Educational Networking Association (GRENA) PSC 03, 15 -16 January 2009, Bucharest 2

Objectives Tehnical objectives § Port the WRF/ARW model to the grid including pre-processing and post-processing. § Run model on very fine resolution § Develop a (quasi-)operationally deterministic forecast chain over the Balkans focused for the needs of Bosnia Herzegovina. § Increase the user community PSC 03, 15 -16 January 2009, Bucharest 3

Partners role in the project RBI § Coordination and leading development of application § Porting model to grid, fine-tunning AMGI § Model development and testing FGA § Inspecting post-processing possibilities (visualization) Uo. BL § Porting model to grid and fine-tuning FHMI § Developing and testing RHMI § Testing, know-how of using model – deployment of operational model GRENA § Testing, know-how of using model PSC 03, 15 -16 January 2009, Bucharest 4

Progress Dynamic application libraries and binaries has been built – WRF version 3. 0. 1. 1 (supporting both Open. MP and MPI) using ifort compiler version 9. 1 Deployed application on UI nodes (home. irb. hr) and storage element (grid 2. irb. hr) Start model locally (on local clusters using MPICH) Start model on grid using one WN (on one CPU, 64 bit CE) Try first runs on grid using 4 CPUs Start working on the script for running the model on the grid (automatization of process for submitting the model and collecting data from distance SE to CE) Organize training event for meteorologists (grid basics and WRF model) Bulit and run pre-processing (WPS) on grid PSC 03, 15 -16 January 2009, Bucharest 5

FHMI progress Compile WRF ARW model (version 3. 0. 1. 1) with PGI Fortran compiler Run model on in cluster environment with 4 CPUs using MPICH 2 and on one node on SEEGRID-SCI site at Faculty of Electrical Engineering, University of Sarajevo (BA-03 ETFSA). Working on running WRF ARW model with MPICH 2 library on all nodes on the BA-03 -ETFSA site. PSC 03, 15 -16 January 2009, Bucharest 6

RHMI progress At first time, RHMI Banja Luka and FHI Sarajevo installed numerical weather model – WRF-ARW version 3. 0. 1. 1 (in October 2008) Nowadays, RHMI BL is testing model (WPS, ARWpost, Gr. ADS…) and providing the support in equipment for operational weather forecast model They are planning to run other models, like WRF/NMM and Eta slope Next step: run WRF-ARW model on Grid using cluster in Uo. Bl PSC 03, 15 -16 January 2009, Bucharest 7

Action points till next PSC Finish porting to the grid’s storage elements binaries and input static data(geo_data) – M 11 Finish scripts for automatisation of starting model on grid infrastructure (collecting all data and binaries) – M 11 Tune application for start on multiple WN (using MPI) – M 10 Finish research mode of WRF-ARW application (ready for use for research purposes till the M 12) - M 12 PSC 03, 15 -16 January 2009, Bucharest 8

Discussion 1. Final decision which binaries to use (32 or 64 bit), INTEL (free license) or PGI 2. File scheme on storage, physical organization of all WRF binaries and other file and libs, which storage elements to use (which are the best for us) 3. Should we pre-process geo_data (geogrid. exe in WPS)? § Should every partner prepare geo_data for his scope of interest and store them at the same place? (better sharing data) 4. Uniform naming for all files and data (to be the same for every partner to avoid collision of data and files)? 5. Dedicided CE elements for WRF – inspection? 6. Funcionality of scripts for starting model? 1. 2. Copy to/from SE elements directly or UI, changing parameters – namelist. input, met_data WPS and ARW – one or two scripts? PSC 03, 15 -16 January 2009, Bucharest 9

Discussion 7. Allocation of work among partners: 1. 2. 3. Making scripts for model starting on grid Preparation of input geo_data (met_data) – uploading on SE Testing for best working nodes/CE – ex. fast WN interconnection PSC 03, 15 -16 January 2009, Bucharest 10
