The annual NITRD Program Supplement to the President’s Budget provides a technical summary of NITRD research investments and activities planned and coordinated through the NITRD Program in a given Federal budget cycle, as required by the High-Performance Computing Act of 1991 (P.L. 102-194) and reauthorized by Congress in the American Innovation and Competitiveness Act of 2017 (P.L. 114-329). The budget reporting and technical program summaries are organized by NITRD Program Component Areas (PCAs). The Supplement provides NITRD members’ budget reporting for the most recently completed budget cycle, the current budget cycle, and the budget requests for the next fiscal year. Budget information for the entire span of the NITRD Program, mirroring that reported in the annual Supplements, is captured in visual and interactive forms in the NITRD Dashboard.

The NITRD PCAs are major subject areas for Federal IT R&D. PCAs are intended to facilitate budgetary comparisons from year to year in each area. The PCA set evolves over time, reflecting changes in IT R&D activities at Federal agencies and IT R&D priorities of the Administration.
