NOTES

1. See the subsections "Programming" and "Algorithms" in Appendix A for a discussion of development and achievements to date.

2. Based on briefings to the committee by Anita Jones (Department of Defense); Duane Adams, Howard Frank, and John Toole (Advanced Research Projects Agency); and Victor Reis (Department of Energy).

3. See NCO (1994), p. 15. Note that figures represent the President's requested budget authority for FY 1995. Actual appropriated levels were not available at press time. Because the HPCCI is synthesized as a cross-cutting multiagency initiative, there is no direct "HPCCI appropriation."

4. This risk is illustrated in the GAO examples of standards setting and other nonresearch activities under the HPCCI umbrella.

5. A January 6, 1995, press release from the Office of Science and Technology Policy announced the resignation of the NCO's director. Donald A.B. Lindberg. Lindberg, requesting that a successor be named when his current 2-year term ends, recommended that a full-time director be appointed at this point in the evolution of the HPCCI.

6. Letter dated August 8, 1994, to Marjory Blumenthal (CSTB) from Donald A.B. Lindberg (NCO/NLM) in response to the committee's interim report (CSTB, 1994c).

7. The committee shares OSTP Director John Gibbons' concerns about the centralized management advocated by GAO (1994, p. 34).

8. The committee notes the extreme fruitfulness of this model in the hands of the late Sidney Fernbach of DOE's Lawrence Livermore National Laboratory, who for a generation kept his laboratory at the forefront of computing and at the same time helped to stimulate the development of generations of supercomputers.
