Four projects win $3.3m of supercomputer hours

Artemis, the University’s supercomputer, will help researchers study the dark side of the Universe, discover new pathogens and build the next generation of internal combustion engines with low toxic emissions.

Four research projects spanning astrophysics, geoscience, engineering and genomics have won the equivalent of $3.3 million worth of hours on the University’s supercomputer, Artemis.

As winners of the 2017 Artemis HPC Grand Challenge, the four research groups will receive 75 million hours on Artemis over four years, as well as expert engineering resources through the Sydney Informatics Hub.

Deputy Vice-Chancellor (Research) Professor Duncan Ivison said the Artemis HPC Grand Challenge and future upgrades to Artemis, which will more than double the machine’s computing power, are part of the University’s investment in its Core Research Facilities and are placing the University at the forefront of computational research.

Understanding the dark side of the universe

Professor Geraint Lewis and Professor Joss Bland-Hawthorn, along with their teams at the Sydney Institute for Astronomy, will investigate fundamental aspects of cosmic evolution. This will include shedding light on the dark side of the Universe, where the stars and gas that we see represent only four percent of the mass/energy content of the cosmos, with the rest being hidden in the ‘dark sector’. The project will also dig into the complexities of the physics of gas in galaxies, revealing how the ebb and flow, collapse and feedback of gas within haloes of dark matter forms the complexity of the universe we see around us.

Discovering new pathogens

Professor Edward Holmes and his team from the Faculty of Science will reveal the Australian virome, or the viruses that infect our native fauna, through RNA sequencing and metagenomics analysis. The team will also conduct surveys of vectors for human and animal diseases including ticks, fleas and mites. The data generated by this project will provide major insights into how pathogens jump species boundaries to emerge as new diseases.

Building the next generation of internal combustion engines

Dr Fatemeh Salehi, Dr Matthew Cleary and their team from Engineering and Information Technologies will build the next generation of internal combustion engines offering high thermal efficiency with low toxic emissions. To achieve this, the team will use advanced computational capacities to study liquid atomisation, soot formation and partially premixed combustion.

Modelling the deep Earth to predict climate change

Dr Tristan Salles, Professor Dietmar Müller and their team at the University’s EarthByte Group will simultaneously model deep Earth and surface processes to better understand climate change. The carbon cycle and its interaction with plate tectonics and deep Earth processes play a key role in regulating Earth’s global climate but a mechanistic understanding of the linkages between these elements remains elusive.
