Abstract新疆天文台Taurus高性能计算系统由1个登陆节点、16个计算节点、2个I/O节点、100TB高速存储组成。其CPU理论双精浮点计算能力6.7584Tflops,通过Linpack测试实际峰值为6.289Tflops,可提供计算能力为理论值的93.06%;GPU理论计算能力18.72 Tflops,实际测试计算峰值为14.882Tflops,计算效率为理论能力的79.5%。系统计算与存储节点均采用56Gb Infiniband交换互连,通过IOZone测试存储系统,单节点写可达460MB/s,多节点写可达800MB/s。系统已在多相滤波及消干扰GPU算法加速、蒙特卡罗模拟等领域得到了应用。
Other AbstractTaurus high performance computing system of Xinjiang Astronomical Observatory has 1 login node,16 compute nodes,2 I/O nodes and 100TB high-speed storage. In theory, the double precision floating-point computation capacity of CPUs is 6.7584Tflops. The actual peak turns out to be 6.289Tflops tested by Linpack, the available computation capability is 93.06% of the theoretical value. The computation capacity of the GPUs is 18.72Tflops in theory, while its practical peak is 14.882Tflops, the available computation capability is 79.5% of the theoretical value. The calculation nodes and the storage nodes are connected by 56Gb Infiniband network. Using IOZone for testing the storage performance, single-node writing reaches 460MB/s and multi-node writing can be 800MB/s. The Taurus HPC system has been applied in various fields such as GPU algorithm acceleration and Monte Carlo simulation.
