본 논문에서는 클러스터 컴퓨팅 환경에서 가용한 자원의 추이를 고려한 자원 스케줄링 최적화 방법을 제안한다. 제안하는 스케줄링 방법은 데이터 인텐시브 응용의 특성인 자원 추가에 따른 처리 성능의 선형적 확장성을 활용하는데, 사용자가 작업 수행을 위해 명시한 자원이 가용하지 않은 경우에 해당 자원이 가용해질 때까지 기다리는 것이 아니라 가용한 자원 상황 추이를 고려하여 융통성 있는 자원 할당을 하게 함으로써 자원 조각화를 최소화한다. 시물레이션을 통한 실험으로 제안하는 방법이 기존 방법에 비해 자원 활용률과 처리량 측면에서 우수함을 검증하였다.
