PLAN FOR DEVELOPING EXASCALE COMPUTING AND INCORPORATING SUCH COMPUTING INTO THE STOCKPILE STEWARDSHIP PROGRAM.

SEC. 3129. [50 U.S.C. 2521 note] PLAN FOR DEVELOPING EXASCALE COMPUTING AND INCORPORATING SUCH COMPUTING INTO THE STOCKPILE STEWARDSHIP PROGRAM. (a) Plan Required.—The Administrator for Nuclear Security shall develop and carry out a plan to develop exascale computing and incorporate such computing into the stockpile stewardship program under section 6111 of title 10, United States Code, during the 10-year period beginning on the date of the enactment of this Act. (b) Milestones.—The plan required by subsection (a) shall include major programmatic milestones in— (1) the development of a prototype exascale computer for the stockpile stewardship program; and (2) mitigating disruptions resulting from the transition to exascale computing. (c) Coordination With Other Agencies.—In developing the plan required by subsection (a), the Administrator shall coordinate, as appropriate, with the Under Secretary of Energy for Science, the Secretary of Defense, and elements of the intelligence community (as defined in section 3(4) of the National Security Act of 1947 (50 U.S.C. 3003(4))). (d) Inclusion of Costs in Future-Years Nuclear Security Program.—The Administrator shall— (1) address, in the estimated expenditures and proposed appropriations reflected in each future-years nuclear security program submitted under section 3253 of the National Nuclear Security Administration Act (50 U.S.C. 2453) during the 10-year period beginning on the date of the enactment of this Act, the costs of— (A) developing exascale computing and incorporating such computing into the stockpile stewardship program; and (B) mitigating potential disruptions resulting from the transition to exascale computing; and (2) include in each such future-years nuclear security program a description of the costs of efforts to develop exascale computing borne by the National Nuclear Security Administration, the Office of Science of the Department of Energy, other Federal agencies, and private industry. (e) Submission to Congress.—The Administrator shall submit the plan required by subsection (a) to the congressional defense committees with each summary of the plan required by subsection (a) of section 6114 of title 10, United States Code, submitted under subsection (b)(1) of that section during the 10-year period beginning on the date of the enactment of this Act. (f) Exascale Computing Defined.—In this section, the term “exascale computing” means computing through the use of a computing machine that performs near or above 10 to the 18th power floating point operations per second.
