- GeoNetwork – NCI’s portal to the data collections, providing download links as well as metadata, author information and access conditions.
- Giga/Tera/Peta – Unit prefixes denoting factors of a billion (1 followed by 9 zeros), a trillion (1 followed by 12 zeros) and a quadrillion (1 followed by 15 zeros). NCI currently stores over 50 petabytes of data and operates a multi petaflop supercomputer.
- GPU – Graphics Processing Unit, a specialised processor with distinctive highly parallel structures making them effective at processing large blocks of data in parallel.
- GSKY – NCI’s scalable, distributed geospatial data server (pronounced ji-skee), which surfaces the large geospatial data stored at NCI using on-demand processing for real-time analysis of nationally significant datasets.
- HDR – High Data Rate, the 200 gigabit per second generation of Mellanox’s networking communications technology Infiniband.
- HPC – High-Performance Computing, the use of parallel processing for running advanced scientific and research applications on large computing systems.
- HPD – High-Performance Data, the use of combined big data collections and high-performance computing for advanced analytics and data processing.
- Lustre – A parallel distributed file system, used at NCI to manage dozens of petabytes of research data in a powerful, efficient and secure way.
- NCMAS – The National Computational Merit Allocation Scheme, a merit-based scheme providing researchers from Australian research organisations with access to Australia’s major national computing facilities.
- NERDIP – The National Environmental Research Data Interoperability Platform, an integrated platform for users to access datasets managed at NCI using access services, data discovery standards and storage infrastructure.
- Network – The communication system carrying data across the nodes of a High-Performance Computing cluster.
- Raijin – NCI’s supercomputer from 2013 to 2019, which was ranked 23rd fastest in the world at launch.
- Service Unit –A service unit (SU) is defined to be a measure of high-performance computing resources for the purposes of entitlement and usage accounting. The primary definition of a service unit is in terms of compute resource accounting, i.e. cpu-hours on NCI’s peak compute system, however SU equivalences are also defined high-performance storage and cloud resources accounting purposes.
- Supercomputer – A supercomputer is a computer made up of thousands of connected compute nodes designed to work in parallel and solve large, complex scientific research and modelling problems.
- THREDDS – NCI’s primary data server through which data collections are accessed.
- Top500 List – A biannual ranking of the world's most powerful supercomputers.
