Britain’s most powerful supercomputer HECToR (High-End Computing Terascale Resource) will be used to simulate everything from climate change to atomic structures
HECToR will run at speeds of up to 63 teraflops – carrying out 63 trillion calculations a second (equivalent to every person on the planet performing 10,000 calculations every second). But it’s a slouch compared with the world’s best supercomputers, ranking only 17th in the world.
