Exascale Computing And Green Energy

What is Exascale Computing?

Exascale computing refers to the next generation of supercomputing systems capable of performing at least one exaFLOP, or one quintillion floating-point operations per second. This level of computational power is a thousand times greater than petascale systems, enabling unprecedented capabilities in data processing, simulation, and artificial intelligence. Exascale systems are designed to tackle complex problems that were previously unsolvable, such as simulating the human brain, predicting climate change with high accuracy, and advancing drug discovery.
