9 Importance of R&D Project ■KOREN based distributed Grid Computing environments Overcome limitations of the meteorology area through Grid  Limitations on computing, networking and data storing Solve earlier problems based on disaster prevention data Data format for providers ⇒ Data format for consumers Offer common collaborative environments to weather experts Substitute clusters for supercomputers ■Disaster prevention system by forecasting natural disasters RT data transmission, high-speed producing and processing Parallel technology for numerical models on natural disasters  Low-cost RT disaster prediction Severe weather prediction, environments, East Sea earthquake tsunami (a tidal wave)  Currently depend on GTS in the Japan Meteorological Administration

10 Final Goals on R&D Project ■ KOREN based Grid system for international disaster prevention ■ KOREN/APII based international joint production of disaster related prevention data ■ development of high speed data access and process system model ■ parallelization of current SWs and sharing international disaster prevention resources KMA SKKU SWU PKNU UCLA (US) Nagoya U. (JP) NIED (JP)

11 Key Elements on R&D Project ■Current year Sharing data for weather prediction with Japan (APII, Nagoya Univ.) Sharing East Sea seismological information (National Research Institute for Earth Science and Disaster Prevention of Japan) Numerical models for disaster preventions in Grid environments Access Grid for multicasting based on KOREN ■Current year + 1 Sharing and verifying weather data (UCLA) RT transmission of disaster prevention data Development of applications for disaster preventions (MPICH-G2) ■Current year + 2 Use of Data Grid for massive data transmission Use of international core technology for disaster preventions (KOREN, APII)

12 Data for Disaster Preventions ■International data collection for weather prediction, climates, earthquakes and environments for disaster predictions RT and distributed collection of weather prediction, climates, earthquakes and environments over the entire earth  Access Grid Collaborating organizations for international data sharing  Based on APII-testbed ■Disaster prediction modeling based on the data collection RT locating/allocating distributed computational resources  Computational Grid Data acquisition for analyzing and forecasting global weather prediction ■RT delivery systems for disaster predictions information KOREN + Grid technology => constructing IT infrastructure
