초록
슈퍼컴퓨터는 국가의 과학기술 경쟁력에 중요한 국가 기반 기술로 산업계 전반에 큰 영향력을 가진다. 본 연구는 대표적인 슈퍼컴퓨터의 아키텍처와 활용기술을 분석하여 슈퍼컴퓨터의 발전 방향성을 파악한다. 이를 위해, 슈퍼컴퓨터를 특성별로 분류하여 대상을 선정하고 프로세서, 네트워크, 운영체제 및 소프트웨어를 분석한다. 슈퍼컴퓨터의 성능을 향상할 수 있는 기술인 CPU-GPU 하이브리드 구성, 광대역폭 메모리의 활용, 컴퓨터간의 고속네트워크 기술의 활용 현황을 분석한다. 분석 결과를 바탕으로 새로운 슈퍼컴퓨터 아키텍처 연구개발과 활용하는 아키텍처의 활용성을 최대화하는 연구개발 방향성을 제안한다. 본 연구를 활용하여 국가 차원의 연구개발 정책 수립 등의 국가 경쟁력 확보에 도움이 되고자 한다.
Abstract
Supercomputers are important to the nation's scientific and technological competitiveness, and have a great influence on the overall industry. This study analyzes the architecture and application technology of representative supercomputers to understand the development trend of supercomputers. In this study we classify supercomputers by characteristics, and select targets to analyze processing methods, networks, operating systems, and software. Then analyzes the utilization status of CPU-GPU hybrid configuration, wide-bandwidth memory, and high-speed network technology between computers, which are technologies that can improve the performance of supercomputers. Finally we suggest R&D directions of new supercomputer architectures and maximizing the utility of present architectures. This study aims to help secure national competitiveness, such as establishing national R&D policies.
