中文摘要: 在核聚变研究领域中,高性能集群的应用十分广泛.一方面需要借助集群进行高性能计算模拟托克马克中粒子的运动状态,另一方面需要存储大量十分珍贵的放电数据以作后续的数据分析.随着位于中国科学技术大学的大型反场箍缩磁约束聚变实验装置“Keda Torus eXperiment”(KTX)的建设取得重要进展,KTX实验室对于高性能计算以及实验数据存储具有高度的需求.因此,部署了一个高性能集群并对存储做出了安全设计.根据IOzone的测试,GPFS文件系统的冗余性机制发挥了作用,数据的读写性能很稳定.

Abstract:High performance clusters are applied to the study of nuclear fusion. On one hand, the simulation of particles movement in the Tokamak is rely on high performance clusters heavily. On the other hand, valuable discharge data have been storaged for further researches. Keda Torus eXperiment reversed field pinch (KTX) device which is situated in University of Science and Technology of China works well, and the KTX laboratory highly demands for high performance computing and experimental data storage. Therefore, a high performance cluster is deployed and a security design for storage is proposed. Based on IOzone tests, the redundancy mechanism of the GPFS file system works, and the data read and write performance is stable.
