최근 산업의 발전으로 대규모 문제 해결의 요구가 커지고 사용자가 원하는 서비스를 신속하게 받고자 고성능 컴퓨팅에 대한 요구가 계속해서 증가하고 있다. 이에 따라 멀티코어 및 매니코어와 이종 하드웨어의 혼용 등으로 지속해서 발전하는 새로운 고성능 컴퓨팅을 위한 시스템은 컴퓨팅 패러다임을 바꿀 시스템 소프트웨어의 혁신 요소로 등장하였다. 하드웨어를 활용하여 시스템의 성능을 높이기 위해서는 컴퓨팅 요소 간의 통신을 최소화하여 전력 소모를 줄이고, 메모리 계층 구조 및 지역성을 고려하여 성능을 높이는 것이 필요하다. 특히, 응용의 실행 시에 시스템 자원을 최고로 활용할 수 있게 하여 성능을 높이는 런타임 시스템은 하드웨어 및 운영체제를 변경하지 않고 시스템 자원을 최대한 활용하여 성능 최적화를 이룰 수 있는 기술이다. 따라서 본고에서는 런타임 시스템의 기능과 기술 방향을 파악하여 차세대 런타임 시스템에 필요한 기술 및 연구 분야를 전망하고자 한다.
