1. JAXA GRID Activity JAXA/EORC Kengo Aizawa KEIO UNIV Hiromichi Fukui

2. Background • JAXA and KEIO Univ are start to try establishing “Digital Asia” system • In Digital Asia, it required to - search and access distributed data - semi-real timedataprocessing JAXA had two of experiments

3. Purpose • Extract problems to realize Digital Asia system by developing prototype. • Accumulate knowledge, know-how for design of Digital Asia system.

4. Data GRID

5. PostgreSQL Assumed scene for Data Grid 　・Search satellite data to each node seamlessly 　・Databases are geographically distributed 　・Each node has different RDB（PostgreSQL、MySQL、Oracle）system USER node（Nepal） Node （Japan） Oracle Node（Chaina） MySQL

6. PostgreSQL Access to hetero DBMS Oracle My SQL Distributed ＤＢ virtual unification Overview DataGrid For Digital Asia Apply （GT3+OGSA-DAI)、access DB over Firewall Unified data view（virtual XML） adopt 「XQuery」 Interface GT3 + OGSA- DAI JDBC FW Unified data view （Virtual XML） Internet SQL実行 XQuery FADGEサーバ SQL SQL実行 XQueryパーザ GT3 + OGSA- DAI GT3 + OGSA- DAI JDBC Query engine results （ＸＭＬ形式） SQL実行 Procesing metadata Metadata for Unified DB GT3 + OGSA- DAI JDBC Translate XQuery to appropriate SQL

14. Computing GRID Experiment • We estimated following two cases. - submitting 100 dummy* jobs with no data transfer - submitting 100 dummy* jobs with 400MB data transfer * dummy job takes 90sec

15. Results

16. Cyber GRIP ・OJC(Organic Job Controller) Allows you to automatically generate a great number of computing jobs with simple descriptions using a script language. It also allows you to do parameter search, parameter sweep, and parametric study. ・GJES(GRID Job Execution System) - Virtually manages dispersed computing resources (computing servers) and equalizes loads on servers. Not only that, if a computer downs during job execution, automatically determines the downed event and executes the relevant job another computer. - Realizing unified job execution in a computing environment with heterogeneous operating systems
