Small and medium-sized enterprises (SMEs) are the important pillars to support China’s economic development, and high-performance computing plays an important role in promoting scientific and technological innovation. The combination of these two part is of great significance. However, the high threshold of high-performance computing technology hinders the effective application of this technology by SMEs to a certain extent. Based on the high-performance computing environment, we build a convenient and easy-to-use high-performance computing application community. The purpose is to explore the community service mechanism of numerical simulation and computing services for SMEs based on high-performance environment, reduce the threshold of using high-performance technology for SMEs, and establish a set of service specification for the needs of SMEs.
