Frontier, the fastest supercomputer in the world, provides expansive and energy-efficient power, which gives scientists the capability to train large AI models in a responsible way.

ORNL is home to the world's fastest exascale supercomputer, Frontier, which was built in part to facilitate energy-efficient and scalable AI-based algorithms and simulations.

Griffiths and her colleagues are examining how much methane and carbon dioxide is released from the reservoir. Their aim is to better understand and predict how much of these climate-warming gases are coming from reservoirs across the nation.
