The U.S. has formed a $1 billion partnership with Advanced Micro Devices to construct two supercomputers that will tackle large scientific problems ranging from nuclear power to cancer treatments to national security, Energy Secretary Chris Wright and AMD CEO Lisa Su said.

The U.S. is building the two machines to ensure the country has enough supercomputers to run increasingly complex experiments that require harnessing enormous amounts of data-crunching capability. The machines can accelerate the process of making scientific discoveries in areas the U.S. is focused on. Wright said the systems would “supercharge” advances in nuclear power and fusion energy, technologies for defense and national security, and the development of drugs.

Scientists and companies are trying to replicate fusion, the reaction that fuels the sun, by jamming light atoms in a plasma gas under intense heat and pressure to release massive amounts of energy.
