초록

최근 과학 기술이 발전함에 따라 복잡한 문제를 해결하기 위하여 고성능의 계산 자원이 필요하게 되었다. 이러한 요구를 충족시키기 위하여 지역적으로 분산되어 있는 이질적인 고성능 컴퓨팅 자원을 하나로 묶어 거대한 시스템을 구성하는 그리드 컴퓨팅에 대한 연구가 활발하게 이루어지고 있다. 하지만 제한된 자원 안에서 최대한의 결과를 얻어내기 위한 프로세스, 실시간 작업의 총 실행시간을 정확하게 예측할 수 있는 스케줄링 정책이 미흡한 실정이다. 이러한 문제점을 해결하기 위해, 본 논문에서는 시스템 효율성 증대를 위한 시스템 구조, 프로세스를 도출하고, 그리드 컴퓨팅 기반의 작업 방법론 도출, 자원(Agent)의 작업에 대한 문제점을 효율적으로 관리할 수 있는 위험 정책 모듈, 자원 할당 및 문제되는 자원들을 재할당 할 수 있는 스케줄링 기법 및 할당 기법, 자원(Agent) 모니터링을 효율적으로 관리할 수 있도록 그리드 컴퓨팅 기반의 위험 관리 시스템을 제안하였다.

As the development of recent science and technology, high-performance computing resources is needed to solve complex problems. To reach these requirements, it has been actively studied about grid computing that consist of a huge system which bind a heterogeneous high performance computing resources into on which are geographically dispersed. However, The current research situation which are the process to obtain the best results in the limited resources and the scheduling policy to accurately predict the total execution time of the real-time task are very poor. In this paper, in order to overcome these problems, we suggested a grid computing-based risk management system which derived from the system structure and the process for improving the efficiency of the system, grid computing-based working methodology, risk policy module which can manage efficiently the problem of the work of resources(Agent), scheduling technique and allocation method which can re-allocate the resource allocation and the resources in problem, and monitoring which can manage resources(Agent).
