Solution

The Square Kilometre Array (SKA) Observatory is working with Huawei and the Shanghai Astronomical Observatory to build a prototype SKA regional center for AI-assisted radio astronomy processing. In the described setup, telescope observations from SKA and precursor instruments are transported into a regional data-center environment, where a high-performance computing system provides the main compute tier. That system applies AI techniques and machine learning techniques to accelerate signal processing and scientific analysis tasks such as pulsar searches and radio galaxy detection. The source also says the platform must support transportation, storage, reading, writing, computing, management, archiving, and release of SKA data, indicating an end-to-end pipeline from telescope ingest through large-scale archive and researcher access. The overall implementation is designed to help astronomers process SKA-scale datasets far more rapidly and make extraction of scientific results feasible at petabit-per-second data rates.

Data flow

Data from SKA telescopes and precursor telescopes is moved into SKA regional centers, where a prototype high-performance computing system developed with Huawei applies AI and machine learning to process observations. The resulting datasets are then stored, managed, archived, and released for astronomers to analyze.
