Frontier, the world's fastest supercomputer, performs one quintillion calculations per second, 2 billion times faster than a laptop.

China's Tianhe-3, not ranked this year, might rival Frontier in speed.

Supercomputers address global challenges, from spacecraft development to sustainability.

The US shares Frontier with scientists worldwide, promoting collaborative research.

Supercomputer nodes are building blocks, with CPUs and accelerators boosting performance.

Frontier boasts 74 cabinets, 9,408 nodes, and rapid data transfer.

China's Tianhe-3 possibly has 100 cabinets and 50,000+ nodes, but chip design is key to performance.

US leads in chip technology, while China designs its own due to trade restrictions.

Supercomputers aid science during the pandemic, analyzing genomes and accelerating vaccine development.
