Abstract: Taurus 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.
