Software platform on China SKA Regional Centre prototype system

The Square Kilometre Array (SKA) radio telescope is designed to revolutionize scientific breakthroughs in a variety of scientific fields, and the SKA software system is one of the key factors influencing scientific products. The software environment for processing SKA science data must be versatile, flexible, and adaptable. The SKA Regional Centre (SRC) serves as a platform for astronomers to analyze SKA data, conduct scientific research, and interact with other academics. To enable automated parallel processing of observational data from various scientific fields, Chinese scientists have developed the China SRC-prototype (CSRC-P), installed a job scheduling system widely used by large supercomputers, installed an astronomical software platform capable of processing observational data from current leading radio telescopes, and deployed multiple scientific data processing pipelines. This paper describes the software platform of the CSRC-P as well as pipelines for processing SKA precursor telescope data, such as the low-frequency continuum imaging pipeline, spectral line imaging pipeline, and very long baseline interferometry data processing pipeline. Users worldwide have successfully conducted scientific research on SKA using this platform. The knowledge gained from the construction and operation of this platform will be useful in constructing a full-scale SRC in the future.
