What the FY2027 request buys
Verbatim from the R-2A exhibit for project MSL-02 of PE 0602025E. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.
- Integrate selected approaches for machine-learning-driven compilation in an end-to-end capability for optimization of compiled software for heterogeneous architectures. - Develop techniques to automatically recognize source code patterns that can be allocated to specific hardware accelerators. - Extend evaluation framework to accommodate systems under test that comprise multiple types of hardware accelerators.
The FY 2027 increase reflects continued development of compilation techniques for heterogeneous architectures and expanded work to test and evaluate the techniques on complex systems.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
- Design and implement selected programming-language-specific compiler front ends for transforming source code into a target intermediate representation. - Develop new techniques to model data movement costs and to factor these costs into the compiler optimizations. - Implement an evaluation framework for compilation based on measures such as performance, memory size, and power consumption.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2026 | Enacted | 11.2 |
| FY2027 | Request | 13.1 |
This activity is 3.6% of project MSL-02's FY2027 request and 0.8% of PE 0602025E's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
