Research area grid systems

Research area: Grid systems

  • Interconnectionof geographically distributedand high performance or large number of resourcesto solve complex problems

Internet


Hungarian cluster grid ministry of education

Hungarian Cluster Grid(Ministry of Education)

  • 2002 : 42 PC Linux clusters with 882 PCs

  • 2003 : 99 PC Linux clusters with 2079 PCs

2.5 Gb/s Internet


Goals of the joint project

Goals of the joint project

  • GRID, as a distributed system built to support a specific scientific area

    • Chemistry GRID

  • GRID, as a distributed supercomputing system

    • Parallel execution of chemical applications

  • GRID, as a distributed IT system for supporting complex collaborative work

    • technical preparation: forecast of air pollution, smag warningplans


Goals i chemistry grid

Goals I: Chemistry GRID

  • Strong collaboration with SYMBEX (EU COST) project

    • Establishment of an integrated international metalaboraty, and development of commonchemistry software systems

    • 5 chemistand 5 IT partnersfrom 6 countries

      • MTA SZTAKI, MTA KKKI

    • P-GRADE system (MTA SZTAKI): common tool for the parallelisation of applications

  • Task:integration of P-GRADE inSYMBEX Grid

    • Hungarian chemical programs, which are parallelised in P-GRADE, will be capable to run on SYMBEX Grid

    • Hungarian chemists will be able to access to the SYMBEX Grid


Parallelisation of programs p grade mta sztaki

Parallelisation of programs: P-GRADE (MTA SZTAKI)

  • Integrated graphical program development environment

  • Efficient parallelisation of sequential programs

  • Support for each stage of development life-cycle

    • design

    • execution

    • debugging

    • performance analysis

Goals ii supercomputing grid

Goals II: Supercomputing Grid

  • Tasks:

    • parallelisation of specific chemical applications by means of P-GRADE development environment:

      • modelling: kinetics/dynamics of elementary reactions (MTA KKKI)

      • modelling of reaction-diffusion systems with sophisticated chemical mechanisms – calculation of air pollution (ELTE FKT)

    • Further development of P-GRADE to support Grid applications:

      • Migration of applications in the Grid

      • Development of efficient information system for handling of grid resources

Goals ii i complex collaborative application

Goals III:Complex collaborativeapplication

  • Task:

    • Forecast of air pollution in Hungary

      • Modelling of air polluted atmosphere by parallel applications – ozone near to surface (ELTE FKT, MTA KKKI, MTA SZTAKI)

      • Integration to meteorological forecasting program (OMSZ)

    • EU directive on the measurement of surface ozone:

      • obligatory short-range forecasting

      • information providing to resident population


Application for air pollution forecast

Application for air pollution forecast

  • Execution

    • Short-range forecast - operative running (OMSZ)

      • supercomputer (IBM Regatta)

      • co-operating with ALADIN meteorological forecast model

    • Technical preparation of smog warning plans

      • Running on the grid  larger computational capacity

      • Simulation of the former smog events and analysis of the efficiency of smog alarm plans

      • Demonstration project for the further complex Grid applications
