  1. GRID technologyby SZTAKI MTA SZTAKI Laboratory of Parallel and Distributed Systems www.lpds.sztaki.hu

  2. Collaborative Grid systems • Goal: Solving very complex problems that require the collaboration of • various fields of science • various (even geographically distributed) institutions • Demo example: • Nowcast: weather forecast for ultra-short time period (30 min) • Collaborative partners: • OMSZ (Országos Meterológiai Szolgálat) • MTA SZTAKI

  3. MEANDER Nowcast Program Package • Goal: Analysis of all the available meteorology information • producing parameters on a regular mesh (10km->1km) • ultra-short forecast • Application: Forecasting dangerous weather situations (storms, fog, etc.) • METEOROLOGY INFORMATION: surface level measurements, high-altitude measurements, radar, satellite, lightning, results of previous computed models, etc. • BASIC PARAMETERS: pressure, temperature, humidity, wind • DERIVED PARAMETERS: type of clouds, visibility, etc.

  4. Structure of MEANDER First guess data ALADIN SYNOP data Satelite Radar Lightning CANARI Delta analysis decode Basic fields: pressure, temperature, humidity, wind. Radar to grid Rainfall state Derived fields: Type of clouds, visibility, etc. Satelite to grid Visibility Overcast GRID Type of clouds Current time Visualization For users: GIF For meteorologists:HAWK

  5. SZTAKI Grid Solution: TotalGrid • The TotalGrid system integrates the different software layers of a Grid (see next slide) and provides for companies • exploitation of free cycles of desktop machines in a Grid environment after the working hours • achieving supercomputer capacity using the actual desktops of the company without further investments • Development and test of Grid programs

  6. Layers of TotalGrid P-GRADE PERL-GRID Condor v. SGE PVM v. MPI Internet

  7. P-GRADE version of MEANDER

  8. Live demo of MEANDER based on TotalGrid P-GRADE PERL-GRID 11/5 Mbit Dedicated job ftp.met.hu HAWK netCDF 34 Mbit Shared netCDF output job netCDF input netCDF output 512 kbit Shared PERL-GRID CONDOR-PVM Parallel execution

  9. Results of the delta method • Temperature fields at 850 hPa pressure • Wind velocity and direction on the 3D mesh of the MEANDER system

  10. On-line Performance Visualization in TotalGrid P-GRADE PERL-GRID 11/5 Mbit Dedicated job ftp.met.hu netCDF 34 Mbit Shared job netCDF input GRM TRACE GRM TRACE 512 kbit Shared PERL-GRID CONDOR-PVM Parallel execution and GRM
