Abstract

Web based simulation service is actively utilized to computably analyze various kinds of phenomena in real world according to progress of computing technology and spread of Network. However it is hard to share data and information among users on the services, because most of web based simulation services do not share and open simulation processing information and results. In this paper, we design a simulation provenance data sharing service on EDISON_CFD (EDucation-research Integration Simulation On the Net for Computational Fluid Dynamics) to share the calculated simulation performance information. To store and share the simulation processing information, we define the simulation processing step as "Problem ${\rightarrow}$ Plan, Design ${\rightarrow}$ Mesh ${\rightarrow}$ Simulation performance ${\rightarrow}$ Result ${\rightarrow}$ Report." Users can understand a problem solving method through a computer simulation by searching the simulation performance information with Search/Share API of the store. Besides, this opened simulation information can reduce the waste of calculation resource to process same simulation jobs.

컴퓨팅 기술의 발달과 네트워크의 확산으로 보다 쉽게 실세계의 다양한 현상들을 수치적으로 분석할 수 있는 웹기반 시뮬레이션 서비스가 활발히 이용되고 있다. 그러나 대부분의 서비스에서 시뮬레이션 수행 내역이 공유/공개되지 않아 사용자들이 같은 실험을 반복해서 수행해야하고 데이터나 정보를 공유하기 어렵다. 이 논문에서는 첨단 사이언스 교육 허브 (EDISON, EDucation-research Integration Simulation On the Net)의 열유체 분야 시뮬레이션 서비스를 중심으로, 기존에 수행된 시뮬레이션 수행내역을 공개할 수 있는 이력출처 데이터 공유 서비스를 설계한다. 공유 서비스를 위해 EDISON_열유체 시뮬레이션 수행 과정을 "문제 ${\rightarrow}$ 계획, 설계 ${\rightarrow}$ Mesh ${\rightarrow}$ 시뮬레이션 수행 ${\rightarrow}$시뮬레이션 결과분석 ${\rightarrow}$ 보고서"로 정의하고 이에 맞게 기존의 시뮬레이션 수행 정보를 저장한다. 사용자는 이력출처 스토어의 검색/공유 API를 통해 시뮬레이션 수행 내역을 검색하여, 시뮬레이션을 통해 어떤 문제가 어떻게 해결되는지를 이해할 수 있다. 또한 동일한 시뮬레이션을 수행하는 시간과 계산자원의 낭비를 줄일 수 있다.
