The High-Performance Computing System for Earth sciences is mainly to provide a unified computing and storage resources for the application of Earth System Numerical Simulation Facility softwares. The system includes 2,200 general computing nodes and 1,160 professional acceleration nodes, connected via a HDR InfiniBand Network with a bandwidth of 100 Gbps. It has more than 200,000 CPU cores with a total memory of 834 TB. Its theoretical computing peak of 15.9 PFlops, and the online storage is approximately 75 PB while the offline storage is 51 PB. The High-Performance Computing System for Earth Sciences uses the CentOS 7.6 operating system and the Slurm job scheduling system, and is equipped with common compilers, mathematical libraries, parallel computing libraries, and heterogeneous computing environments. It is capable of providing strong supports for both general and heterogeneous computing.
