Abstract

본 논문에서 제안하는 시스템은 일반적인 병렬 시스템의 하드웨어 구조에서, 다중 스레드 계산 모델을 이용하여 객체 지향 프로그래밍 환경을 구현한 시스템이다. 제안하는 시스템을 효과적으로 구현하기 위하여 컴파일러와 실행 시간 시스템의 측면에서 여러 가지 기법을 제시한다. 컴파일러의 측면에서는 멤버 변수의 접근 분석, 메소드의 병렬성 분석 기법을 제시하고, 실행 시간 시스템에서는 실시간 스레드/메시지 결합, 프레임 공유 기법을 제시한다. 본 논문에서 제안된 프로그래밍 환경은, MPI 메시지 인터페이스를 이용하여 구현하였으며, 벤치마크 프로그램을 실행함으로써 성능 분석을 하였다. 분석의 결과는 실행시간 시스템의 여러 가지 기법들이 성능 향상에 많은 효과가 있음을 보여주며, 이러한 결과는 일반적인 병렬 시스템에서도 적용 가능하다.Abstract In this paper, we suggest an object-oriented programming environment with multithreaded computation model on general parallel processing systems. We developed many methods for our environment to be efficient : in compiler, the analysis of member variable and method parallelism, and in runtime system, thread/message merging and frame sharing. The programming environment is implemented with MPI message interface, and its performance is analyzed with executing benchmark programs. The results show that the developed methods have influence on performance improvement, and this improvement can be applied to general parallel processing systems.
