NCI’s newest supercomputer is Gadi, a 3,200-node supercomputer supplied by Fujitsu Australia. Named Gadi (pronounced 'gar dee') after the words “to search for” in the language of the Ngunnawal people, the traditional owners of the Canberra region, Gadi is Australia's peak research supercomputer for 2020 and beyond.
Gadi offers a 5-10 times increase in computational performance, and a significantly increased number of GPUs compared to its predecessor the Raijin supercomputer. This provides significant benefits for the largest parallel codes in particular, and all users will benefit from shorter queues and higher throughput.
Gadi first launched to NCI users in mid-November 2019. The public launch is phased, with the first portion of the new machine launching in November and the second phase launching in January 2020. User documentation about the new machine is on our dedicated information page.
The Gadi installation is documented on our dedicated blog, click here to see the latest progress.
- When complete, Gadi will include around 3,000 nodes containing Intel's second-generation Xeon Scalable ‘Cascade Lake’ processor with two 24-core CPUs and 192 Gigabytes of RAM per node.
- Gadi will also include 160 nodes containing 640 Nvidia V100 GPUs, and 50 large-memory 'Cascade Lake' nodes offering 1.5 Terabytes of Intel Optane DC Persistent memory.
- Linking the storage and the computer is Mellanox Technologies' latest generation HDR InfiniBand technology in a Dragonfly+ topology, capable of transferring data at 200 Gb/s.
- The underlying storage sub-systems are provided by NetApp enterprise class storage arrays, linked together in a DDN Lustre parallel file system enabling the high-performance throughput needed for computing on big data challenges.
- Altair’s PBSPro software optimises job scheduling and workload management.
- Gadi uses the latest version of the CentOS 8 operating system.
