Summary
The U.S. is building the two flagship supercomputers, 3x
faster than today’s fastest system.
Higher performance supercomputers are necessary to enable
new waves of scientific innovation and discovery, such as
delivering safe fusion energy, combating climate change,
finding new alternative energy, and enabling better, safer
consumer products.
IBM & NVIDIA are inventing new technologies that will enable
exascale computing
