Abstract

We performs the cost-benefit analysis, an economical analysis technique, to measure the effect of a shared public supercomputer. The costs of two given alternatives, to share the public supercomputer in a national center and to employ their own supercomputers in the organizations under the necessity, will be estimated and compared for decision making. In the case of sharing, we can simply predict the cost based on the results of the previous public supercomputer. The cost of individual introduction, however, is almost unpredictable since it has a remarkable variability due to the required system performances, locations, human factor, and so on. Accordingly, an objective and valid method to estimate the cost of individual cases will be proposed in this research. Finally, we analyze the economic effect of operating public supercomputer by comparing the sharing cost with that of the individual employs. The results of analysis confirms that the sharing public supercomputer will reduce the operational cost about 10.3 billion won annually compared with the individual introduction. Accordingly, it is expected that the sharing public supercomputer will bring a considerable economical effect.

본 논문에서는 슈퍼컴퓨터 공동 활용의 효과에 대한 경제성 분석을 비용편익분석 방법을 통해 수행한다. 슈퍼컴퓨터를 활용함에 있어 국가센터 등에서 중앙 집중형 범용 시스템을 운영 및 서비스하는 체제와 개별 기관들이 자체적으로 구축 운영하는데 소요되는 비용을 추정하여 비교한다. 공동 활용의 경우 기존 슈퍼컴퓨터 도입 및 운영 실적에 근거하여 비용을 쉽게 추정할 수 있다. 그러나 개별 사용에 소요되는 비용은 실제로 운영하고 있지 않은 관계로 슈퍼컴퓨터의 성능 및 기반시설, 인적 요인 등에 의한 변동성을 고려한다면 그 추정이 매우 어려운 실정이다. 따라서 본 논문에서는 개별 사용 비용을 산출하는 객관적이고 타당한 방법을 제시하고 두 대안의 비용을 비교하여 공용 슈퍼컴퓨터 운영 서비스가 경제적 측면에서 얼마나 효과적인지를 분석한다. 분석결과에 따르면 공용 슈퍼컴퓨터의 활용이 개별 사용에 비해 운영비용 측면에서 연평균 약 103억원, 6년간 총 620억원이 절감된다. 따라서 공용 슈퍼컴퓨터의 활용은 개별 도입에 비해 상당한 규모의 경제적 효과를 가져 올 것으로 판단된다.
