Supercomputer for climate research
Jun 23^rd, 2020 at 2:02pm

Supercomputer heralds improved climate forecasting.

Researchers are now making use of the Australian National University's new supercomputer, Gadi, one of the most powerful of its kind and the most powerful in the southern hemisphere.
Key points:

The artwork featured on Australia's new supercomputer is by Ngunnawal artist Lynnice Church
With enhanced processing capabilities, Gadi offers hope for vastly improved research
The Bureau of Meteorology hopes to use Gadi to better predict bushfire behaviour

Gadi, based at the National Computational Infrastructure (NCI), was unveiled this week after a few months of early operation, described by the university as a "recognised powerhouse in the global supercomputing ranking".

The supercomputer, which operates 24/7 for 360 days a year, uses the same amount of electricity as it takes to power a medium-sized suburb.

Among the more than 5,000 individuals using the supercomputer — remotely from their offices — will be researchers from the Bureau of Meteorology, CSIRO and Geoscience Australia.

Both CSIRO and Geoscience Australia will use the supercomputer to improve their systems aimed at predicting extreme weather patterns, including fires, earthquakes, tsunamis and cyclones.

The CSIRO's executive director of Digital, National Facilities and Collections, Dave Williams, said having an asset like Gadi was "critical" for predicting Australia's future.

He said its computational models would contribute to the CSIRO's Decadal Climate Forecasting Project to produce "near-term" climate forecasts.

"Gadi will enable our work in Earth sciences including climate, land, water and fire modelling," Dr Williams said.

"The data that Gadi will process and analyse is collected here on Earth as well as by an increasing number of satellites orbiting our planet."

Technical specs

Gadi contains a total of 145,152 CPU cores, 567 Terabytes of memory and 640 GPUs.

3,024 nodes each containing two 24-core Intel Xeon Scalable ‘Cascade Lake’ processors and 192 Gigabytes of memory.
including 50 nodes each offering 1.5 Terabytes of Intel Optane DC Persistent memory.
160 nodes each containing four Nvidia V100 GPUs and two 24-core Intel Xeon Scalable ‘Cascade Lake’ processors.
Linking the storage systems and Gadi is Mellanox Technologies’ latest generation HDR InfiniBand technology in a Dragonfly+ topology, capable of transferring data at up to 200 Gb/s.
The storage sub-systems are NetApp enterprise class storage arrays, linked together in a DDN Lustre parallel file system.
Altair’s PBSPro software optimises job scheduling and workload management.
Gadi uses the latest version of the CentOS 8 operating system.

Global warming is settled in the sense that the experts agree it's happening.

Of course, there also are plenty of wannabes and fringe nutters who delude themselves that they are a legitimate part of the scientific debate and who believe that the scientists are either hugely mistaken or conspiring to commit a massive hoax.

You mean people like Al Gore and Monk?

Al Gore is not an expert on climate science.
David Dubyne is not an expert on climate science.

Neither are capable of contributing to scientific debate because they aren't doing climate science.
