More than 7 times faster than the current fastest supercomputer, Frontier will probably end up even faster than Intel's Aurora exascale supercomputer scheduled to go operational around the same time frame. Frontier will combine the power of the current top 160 fastest supercomputers in the world and will help scientists forecast global warming patterns, engineer better pharmaceuticals and run extensive cosmological simulations.
