· Basic hardware technology (BHW)-basic electronics research supporting electronic components that might be applied to a wide variety of systems, including computers and communications systems;

· Education (EDU)—training and education; and

· Administration (ADM)—National Coordination Office.

The committee classified 86 of the 88 program elements as coming under I of the 11 disciplines listed above, based on each program element's FY 1995 milestones (Table C.1). If a program element appeared to fit into more than one discipline, the committee categorized it by examining the element's milestones to determine where the majority of the program activity was concentrated. Two of the larger Advanced Research Projects Agency (ARPA) program activities (Intelligent Systems and Software, and Information Sciences) were split between two disciplines.

Table C.2 shows the FY 1993 actual budget, the FY 1995 request,2and the percentage change in the HPCCI budget for each of these 11 disciplines.

BUDGET REVIEW

It is interesting to examine the HPCCI budget to see which areas are being emphasized and to compare these with the HPCCI's goals and objectives. As indicated also in Chapter 2, the current program goals are as follows:

· Extend U.S. leadership in high-performance computing and networking technologies;

· Disseminate the technologies to accelerate innovation and serve the economy, national security, education, and the environment; and

· Spur gains in U.S. productivity and industrial competitiveness.

The computer technology, software technology, and communications technology disciplines address the goals of extending technical leadership in computing and communications and providing key enabling technologies for the information infrastructure. The budget for these three disciplines accounted for 32.9 percent of the FY 1993 actual budget and 30.5 percent of the FY 1995 requested budget.

The largest part of the HPCCI budget is invested in applications and supercomputer computing infrastructure to support applications—49.8 percent of the FY 1993 actual budget and 50.1 percent of the FY 1995 requested budget. Applications and computational science, common applications support, artificial intelligence and human-machine interaction, and computing infrastructure programs are included. The rest of the budget requested for FY 1995 is divided among basic hardware technology (5.1 percent), communications infrastructure (7.9 percent), education (5.6 percent), and a very small amount for program administration.
