Delving deep into genomes

“Once the data gets on to our filesystem, the workflow uses NeSI’s A100 GPUs to execute the first step of the analysis at lightning speed."

HPC lowers the barrier when producing hydrogen

“It needs HPC. Some of these dimer calculations wouldn't converge for two or three weeks.”

A neural network to conquer sleep apnoea

Using NeSI allowed us to take the approach of gathering lots of data, then train and test it remotely as opposed to trying to do it all on a local machine."

Diving deeper into earth data analysis

"We are in a better position to make informed decisions about how to work with data in these next generation models and now have access to tools which go beyond previous existing capabilities."

Enhancing the capabilities of autonomous space missions

" I have already saved hours if not days of computational time to develop the guidance algorithms that are the focus of my research."

Supporting faster paths to heart disease insights

"Their engagement prompted us to review our coding and testing methods which has an impact beyond just this project."

Combining physics and artificial intelligence for high-resolution climate projections and sub-seasonal-to-seasonal forecasts

“A lot of learning was trial and error, but it was great to have the support to help us set up scripts."
