Abstract

We designed a portable parallel library HPCL(High Performance Computing Library) with following objectives: (1) to provide a close relationship between the parallel code and the original sequential code that will help future versions of the sequential code and (2) to enhance performance of the parallel code. The library is an interface written in C and Fortran programming languages between MPI(Message Passing Interface) and parallel programs in Fortran. Performance results were determined on clusters of PC's and IBM SP4.

본 연구에서는 병렬프로그램을 효율적으로 개발할 수 있고 병렬처리 프로그램의 성능을 향상시키는 이식성을 갖는 고성능 병렬 라이브러리인 HPCL(High Performance Computing Library)을 구현하였다. HPCL은 C 언어와 Fortran 언어로 구현되었으며, Fortran 프로그램에서 메시지 전송 인터페이스인 MPI(Message Passing Interface)를 효율적으로 사용할 수 있도록 하였다. 성능 분석은 PC 클러스터와 상업용 슈퍼컴퓨터인 IBM SP4를 이용하여 병렬프로그램의 성능 향상 및 통신 오버헤드 등에 대하여 다양하게 이루어졌다.
