Astronomy is entering an era of mega-data that will render conventional research methods as well as data and visual analytics tools ineffective. The Square Kilometre Array (SKA) drives one of the most significant big data challenges of the next decades. South Africa, China and India are partners in the global SKA collaboration and host recently completed, next generation radio astronomy facilities. South Africa, Brazil, China and India are involved in the Large Synoptic Survey Telescope (LSST), which represents a complementary mega-data challenge, vastly increasing the current data volume of optical surveys, and providing critical multi-wavelength data set for SKA analytics. Russian researchers are also engaged in radio astronomy and multi-wavelength, multi-messenger projects driving increasing volumes of observational data. This project brings together teams leading programs in data innovation in each partner country to collaborate on the development of new technologies and systems to meet the big data challenge of SKA pathfinder facilities and the multi-wavelength projects that are critical to the advance of astronomy. In so doing we will prototype and demonstrate scalable big data technologies for the new big data era, and establish a BRICS multinational federated data intensive cloud network for collaborative programs in data intensive astronomy.
天文学正在进入一个大数据时代,这将使传统研究方法以及数据和视觉分析工具失效。平方公里阵列(SKA)是未来几十年最重大的大数据挑战之一。南非、中国和印度是全球SKA合作的伙伴,并拥有最近建成的下一代射电天文学设施。南非、巴西、中国和印度参与了大型综合巡天望远镜(LSST)项目,这是一个互补的大数据挑战,极大地增加了当前光学巡天的数据量,并为SKA分析提供关键的多波长数据集。俄罗斯研究人员也参与了射电天文学和多波长、多信使项目,这些项目产生了越来越多的观测数据。该项目汇集了每个伙伴国家在数据创新方面的领先项目团队,共同合作开发新技术和系统,以应对SKA探路者设施的大数据挑战以及对天文学发展至关重要的多波长项目。通过这样做,我们将为新的大数据时代开发和演示可扩展的大数据技术,并建立一个金砖国家跨国联合数据密集型云网络,用于数据密集型天文学的合作项目。
