Exascale supercomputers are next-generation supercomputers capable of simulating many hitherto unsolvable complex systems at fine-grained resolution and with atomic precision. To do that, exascale supercomputers rely on next-generation processing chips with faster performance and more transistors per unit chip area. However, faster processor speed and more transistor per unit chip area would also drive up … More Viable exascale supercomputers require fast performance with reduced energy consumption
