Setonix is the name of Pawsey’s new supercomputer delivered by Hewlett Packard Enterprise (HPE) as part of the biggest upgrade to the Pawsey computing infrastructure since the Centre opened in 2009. Setonix delivers 30 times more compute power than its predecessor systems Magnus and Galaxy, to help power the future high-impact Australian research projects.
Setonix has been built using the HPE Cray EX architecture, featuring significantly increased compute power and more emphasis on accelerators with future-generation AMD EPYC™ CPUs and AMD Instinct™ GPUs, and including expanded data storage capabilities with the Cray Clusterstor E1000 system.
During the international supercomputing conference SC22 in Texas, Setonix debuted in the Green500 as the fourth greenest supercomputer in the world and in the Top500 list as the most powerful public research supercomputer in the southern hemisphere and the 15th most powerful in the world. You can read more about this here.
The upgraded compute capability provided by Setonix is be supported by a number of other upgrades at the Pawsey Centre designed to provide researchers with an improved user experience:
The ASKAP ingest nodes are one of the most critical components of the pipeline between the ASKAP telescopes and the data store which houses the final data products. They receive the data from the correlators located at the Murchison Radio Observatory and write them to disk ready for post processing on the Galaxy supercomputer.
As part of the capital refresh, the sixteen ASKAP ingest nodes have been replaced with nodes with the latest AMD processors designed for I/O. They have twice as much data bandwidth as the previous generation and more memory channels, ensuring that they can keep up with the torrents of data that are produced by the telescopes. Along with three dedicated nodes for providing ancillary services, they have dedicated storage in the form of the ClusterStor E1000. Approximately half a petabyte of NVMe storage has been dedicated to the ingest process, capable of speeds in excess of 150 GB/s.
The new MWA Compute Cluster is named “Garrawarla”, meaning spider in the Wajarri language; whose land the Murchison Radio Observatory is on. The new 78-node cluster provides a dedicated system for astronomers to process in excess of 30 PB of MWA telescope data using Pawsey infrastructure. The new cluster provides users with enhanced GPU capabilities to power AI, computational work, machine learning workflows and data analytics.
The Nimbus high-throughput computing (HTC) infrastructure has been upgraded. The new infrastructure provides improved computational flexibility, accessibility and speed. The upgrade allows researchers to process and analyse even larger amounts of data through additional object storage and the Kubernetes container orchestrator, building on Pawsey’s existing container technology for its HPC systems.
Acacia is the new online storage system and provides over 60 PB of object storage for long term archiving of researcher data. The system is divided into two zones, one designed for data which needs to be accessed faster than the other which is designed for energy efficient long-term storage.
Banksia is the new offline storage and provides a replacement of the previous storage management software with an open system which provides an expandable platform to build on and leverage the investment in object storage. It uses Pawsey’s current investment in tapes by re-using the existing tape libraries and utilise a new 5 PB cache to take full advantage of the new 100 GBe network infrastructure.
Pawsey has moved from a monolithic single core router to a spine-leaf architecture with a 400Gbps backbone and 100 Gbps links to host endpoints. This allows all network endpoint (ie. login nodes, visualisation servers, data mover nodes, etc.) to realise a ten-fold increase in bandwidth from moving from 10 Gbps to 100 Gbps ethernet.
To support all the above upgrades to the Pawsey Supercomputing Research Centre, the Pawsey building has been upgraded to provide power and cooling to the new infrastructure.

Pawsey Capital Refresh Status
Setonix has been delivered using HPE Cray EX supercomputer architecture and provides 30x more compute power than its predecessors and is 10x more power efficient.
Setonix debuted in the Green500 as the fourth greenest supercomputer in the world and in the Top500 list as the most powerful public research supercomputer in the southern hemisphere and the 15th most powerful in the world.
Pawsey partnered with Dell EMC to expand its cloud system with 5x more memory and 25x more storage to form a cutting-edge flexible compute system.
This expansion provides better service to emerging research areas and communities that benefit more from a high throughput compute.
Astronomy high-speed storage: 3x more storage and performance. The existing Astro filesystem was expanded to service the MWA community. Powered by HPE, it has been upgraded to 2.7 PB of usable space and capable of reading/writing at 30 GB/s.
The New buffer filesystem, a dedicated resource for ASKAP researchers, provides 3.7 PB of usable space and is capable of reading/writing at 40 GB/s. It is manufactured by Dell.
High-speed storage filesystems: Designed to deal with thousands of users accessing them at the same time. The Pawsey high speed filesystems deliver increased speed and storage capability to general purpose science.
The remote visualisation capability has been procured as part of Setonix. When the new capabilities become available, researchers will be able to visualise their science in real-time, while being processed.
This new capability will allow researchers to steer their visualisation while the data is processed and fine tuned to the desired outcome.
Pawsey has migrated to a CISCO spine-leaf architecture with a 400Gbps backbone and 100 Gbps links to host endpoints.
Garrawarla, the 546 TeraFlops MWA cluster, is a resource tuned to MWA’s needs, powered by HPE. Procured ahead of the Main Supercomputer, this cluster allows ASKAP to use the full CPU partition of Galaxy.
