University of Queensland’s new supercomputer takes a different IT approach

Maria J. Smith

The College of Queensland (UQ) has acquired a new substantial-general performance computer system (HPC) right after going to market in October 2021.

The HPC identified as Bunya—named just after the indigenous South-East Queensland tree—has two abnormal facets, a person is that as a new and far more effective machine, it will generally substitute UQ’s three current HPCs.

One more facet is that the university took a various tactic as to how updates to Bunya will be accomplished. In earlier deals, UQ would have signed a deal to acquire any even further parts from the vendor offering the device but it is now totally free to look for somewhere else if there is extra price for its end users. This means that UQ will be ready to do upgrades by technology levels, so when one thing commences not undertaking as properly and there is a better engineering accessible it can opt for to enhance just one layer.

Ordered from Dell, Bunya has:

  • ~6000 AMD EPYC Milan sequence cores, 96 physical cores for every node.
  • 2TB of memory for each node on a conventional compute node.
  • 4TB of memory for every node on just about every of the three superior-memory functionality nodes.
  • a blocking topology Infiniband HDR cluster interconnect, operating at a indigenous 200Gbps for each port, for each node.
  • 3 servers well worth of early-accessibility exploratory/cutting-edge programs that contains AMD Instinct MI2xx series GPU accelerators. 
  • a recent era RHEL-style Linux distribution.

In this instance no storage was obtained as the university has pre-current high performance parallel file techniques to supply storage and did not have to procure any more storage.

In accordance to facts from Forrester’s enterprise technographics infrastructure survey from 2021, when questioned what providers would run in the personal cloud, Australian selection makers named HPC solutions as the best a single together with data foundation both of those with 35%, when HPC came as No. 4 for products and services predicted to operate on the general public cloud with 29%.

How Bunya is established up to substitute 3 HPCs

Bunya will replace a few HPCs: Awoonga, FlashLite, and Tinaroo, all a few have been operational for seven yrs.

Awoonga has been decommissioned in March 2022, FlashLite is anticipated to be decommissioned by August 2022, and Tinaroo by 2023. The equipment will be phased out as Bunya is phased into staying entirely operational.

UQ states it does not have programs to build another HPC to swap Awoonga, FlashLite, and Tinaroo because Bunya will combine the specialised aspects of the predecessor HPCs less than one particular technique staying equipped to carry out a vast assortment of study domains from sciences to humanities.

The 1st period of firing Bunya up is predicted for July 2022, when early entry and exam consumers will be utilising the equipment to help calibrate workflows, layouts, schedules and technologies. This screening period is not a mild test, Jake Carroll, CTO at  the College of Queensland Investigation Computing Centre (RCC) tells Computerworld Australia, these are intense end users that assist give quality feedback and helps to get ready the HPC to fulfill the superior expectations of all consumers when it is thoroughly functional, one thing that is predicted to transpire by the stop of 2022.

Changing a few HPCs with just one was possible because of how the technological innovation all-around scheduling different workloads has evolved. Where ahead of it was expense-effective to have unique devices for distinct workloads and researchers would be directed to the proper equipment, this is now a lot simpler to manage, says RCC director David Abramson.

Bunya is predicted to be considerably quicker, “you could transfer an total 23 gigabyte Blu-Ray movie into a node on FlashLite or Tinaroo in close to 3.28 seconds Bunya can attain the identical transfer in .92 seconds,” Carroll mentioned in a assertion.

Bunya is expected to have a equivalent daily life span to its predecessors of among five and seven decades.

When it will come to the HPCs being decommissioned, UQ is searching if it is commercially viable to reutilise any parts of FlashLite.

A various technique for a new significant-efficiency personal computer

Instead than acquiring the most significant machine out there, the University of Queensland RCC—which supplies coordinated administration and help of UQ’s sustained and sizeable expense in e-research—opted for a lightweight and speedy-shifting merchandise which also enables for it to hold up with sector ability.

Section of this new method aids to maintain Bunya up to day with new HPC technologies, which positive aspects the scientists, but also ensures a lesser impression on the atmosphere by being extra energy efficient than its predecessors. This implies UQ is opting for a layered refresh technique each year for at minimum 3 many years to commence with.

In the previous, the university would have been locked in a deal to keep doing the job with the seller of preference, and despite the fact that UQ has the intention to operate with the picked vendor for multiple many years, furnished there is price in that continuation that advantages UQ, there is no contract locking the university to procure even more with Dell.

Yet another motive for this approach is so it can preserve on the existing marketplace edge of silicon.

“So as an alternative of possessing circumstances where a researcher will arrive to us a yr later and say, ‘well, this is terrific what you provided me, but now we’re jogging at a deficit of capability’, or ‘we really do not have enough cores’ or ‘we never have the correct form of cores or accelerator technologies’. And we are suffering from a silicon renaissance at the minute. As much as all these new varieties of processing models are worried, this provides us that higher hand and that means to transfer speedily,” Carroll tells Computerworld Australia.

This is not the to start with HPC that Dell has presented to UQ, in 2017 UQ’s division of molecular biology, neuroscience, and translational analysis begun to construct Wiener with Dell.

A further distinction is that, following Bunya is set and working it will be in the hands of UQ to seem immediately after every little thing else from the software program stack and the administration of offers and safety, which gives UQ management, knowledge and overall flexibility.

Funding a HPC and person obtain

Bunya was funded in its the vast majority by UQ with even more contributions from the Institute for Molecular Bioscience (IMB), the Australian Institute for Bioengineering and Nanotechnology (AIBN)—both are based at UQ—and the Queensland Cyber Infrastructure Foundation (QCIF), at the moment fashioned by 10 customers.

For this explanation, Bunya will be obtainable to all this investing parties and mostly UQ, states Abramson.

Scientists with the university have easy access to the device as opposed to those who may well want to use what the researchers refer to as a tier 1 facility—such as Pawsey or National Computational Infrastructure (NCI). For these, there is normally a method a researcher would have to have to apply for peer evaluation which would be extended than all those now within UQ who can have entry virtually suitable absent. On the other hand, as a member of QCIF, this usually means researchers at all 10 of these QCIF associates have accessibility to QCIF’s HPC providers, which, in accordance to UQ, contains a share of time on NCI’s Gadi.
