The National Computational Infrastructure, Australia’s national high-end computing service, is an initiative of the Australian Government, hosted by The Australian National University. NCI’s mission, to foster ambitious and aspirational research objectives, and to enable their realisation through world-class high-end computing services, is advanced through both cutting-edge infrastructure and internationally renowned expert support. NCI’s advanced computing infrastructure, comprising a petascale HPC system, a large-scale compute cloud (primarily for data-intensive services), and multi-petabyte high-performance storage, is funded through programs of the Department of Industry, Innovation, Science, Research and Tertiary Education, while its operations are sustained through the substantial co-investment by a number of partner organisations including ANU, CSIRO, the Australian Bureau of Meteorology, Geoscience Australia, a number of Australia’s research-intensive universities, and the Australian Research Council.
