OpenACC for tropical circulation model

When new A100 GPU resources were brought online at NeSI, it raised an interesting question for Gilles Bellon: Would offloading computations onto GPUs further improve the performance of his code?

War on wildings

"Building a scientific model/theory to solve complex real world problems is one thing but scaling it up to solve the problems in a timely manner and utilizing all the modern computational resources is another."

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.”

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."
