dc.description.abstract
본 연구에서는 시범적으로 한-중-일 3개 국가에 분산된 클러스터 컴퓨터를 상시 연동할 수 있는 e-Science 테스트베드를 구축함. 계산 환경 구축과 관련, 컴퓨터의 정보를 상시 제공하는 기술, single-sign-on 기술, 이기종 컴퓨터간의 통신기술을 연구함. 또한 구축된 e-Science 테스트베드를 활용한 시범 응용 연구로서 항공기의 유동 해석을 기반으로 하여 연료탱크 등의 분리시 안정성 판별연구를 high-throughput computing 기반으로 수행함. 모든 연구는 전산유체역학 기술을 바탕으로 한-중-일의 컴퓨터를 동시에 활용함. 더불어 개발된 연구 수행 방법 및 결과를 한-중-일 연구자가 활용할 수 있도록 지원하기 위한 웹 기반 서비스 환경 구축 기술을 연구함.
이상과 같은 연구의 유기적 협력을 위하여 동북아 연구자간의 협력 활동을 통하여 e-Science 연구에 있어 한국의 주도적 활동을 추진함.
