A Pulsar [1] is a highly magnetized rotating neutron star that emits a beam of electromagnetic radiation. It is the product of massive star evolution and has the characteristics of small volume, large density, high-speed rotation, and strong magnetic field. Pulsar observation research is helpful to reveal the mystery of the birth and evolution of the universe and has very important scientific significance to promote the development of astrophysics, particle physics, and spacecraft navigation. It has always been a hot spot in the field of astronomy and astrophysics. Pulsar observation and theoretical research have made a rapid progress after Jocelyn Bell discovered the first radio pulsar in 1967 [2]. By October 2018, 2658 pulsars have been confirmed ( ).
Tier 1. Pulsar observation data is synchronized between the storage system of NanShan station and the XAO headquarters through a dedicated 300Mpbs line. Currently, rsync ( ) is used to perform incremental backups from NanShan station to XAO headquarters. All the metadata will be imported into the corresponding database to prepare for data release after extracting the metadata information from pulsar data. The data storage server, the Taurus high performance computing system, and the data release server use a common NFS server to implement the data transmission. For database data, there are backups in XAO headquarters and NanShan station. Users are allowed to log in to Taurus analysis system to download and process the data. A 56 Gbps InfiniBand switch connects the Taurus HPC and the long-term archive in XAO headquarters. All the data processed by users can be archived and released as needed.
