(d)

Exascale computing program

(1)

In general

The Secretary shall conduct a coordinated research program to develop exascale computing systems to advance the missions of the Department. (2)

Execution

The Secretary shall, through competitive merit review, establish two or more National Laboratory-industry-university partnerships to conduct integrated research, development, and engineering of multiple exascale architectures, and— (A)conduct mission-related co-design activities in developing such exascale platforms; (B)develop those advancements in hardware and software technology required to fully realize the potential of an exascale production system in addressing Department target applications and solving scientific problems involving predictive modeling and simulation and large-scale data analytics and management; and (C)explore the use of exascale computing technologies to advance a broad range of science and engineering. (3)

Administration

In carrying out this program, the Secretary shall— (A)provide, on a competitive, merit-reviewed basis, access for researchers in United States industry, institutions of higher education, National Laboratories, and other Federal agencies to these exascale systems, as appropriate; and (B)conduct outreach programs to increase the readiness for the use of such platforms by domestic industries, including manufacturers. (4)

Reports

(A)

Integrated strategy and program management plan

The Secretary shall submit to Congress, not later than 90 days after the date of enactment of the American Super Computing Leadership Act, a report outlining an integrated strategy and program management plan, including target dates for prototypical and production exascale platforms, interim milestones to reaching these targets, functional requirements, roles and responsibilities of National Laboratories and industry, acquisition strategy, and estimated resources required, to achieve this exascale system capability. The report shall include the Secretary's plan for Departmental organization to manage and execute the Exascale Computing Program, including definition of the roles and responsibilities within the Department to ensure an integrated program across the Department. The report shall also include a plan for ensuring balance and prioritizing across ASCR subprograms in a flat or slow-growth budget environment. (B)

Status reports

At the time of the budget submission of the Department for each fiscal year, the Secretary shall submit a report to Congress that describes the status of milestones and costs in achieving the objectives of the exascale computing program. (C)

Exascale merit report

At least 18 months prior to the initiation of construction or installation of any exascale-class computing facility, the Secretary shall transmit a plan to the Congress detailing— (i)the proposed facility's cost projections and capabilities to significantly accelerate the development of new energy technologies; (ii)technical risks and challenges that must be overcome to achieve successful completion and operation of the facility; and (iii)an independent assessment of the scientific and technological advances expected from such a facility relative to those expected from a comparable investment in expanded research and applications at terascale-class and petascale-class computing facilities, including an evaluation of where investments should be made in the system software and algorithms to enable these advances.
