Cloud based Modeling and Simulation Platform
This paper presents the construction of Modeling and Simulation (M&S) platform based on cloud computing. High performance Engineering MOdeling Simulation (HEMOS) is an M&S software developed to support structural analysis and fluid analysis. Developed using open source software, it supports all M&S processes from pre processing to analysis and postprocessing. HEMOS is provided through HEMOS CLOUD which was built based on Xen server with 532 CPU cores and storage of 57.5 TB. HEMOSCLOUD consists of four hardware groups such as master, analysis, design and development for effective resource utilization and management. HEMOSCLOUD provides job scheduling function using SGE and is developed to enable large scale analysis by connecting with KISTI's supercomputer Tachyon2. This cloud based M&S platform that implemented using opensource solvers and libraries can increase user accessibility and reduce production time and costs.
