Requires the Director of the Office of Science and Technology Policy to: (1) establish the goals and priorities for Federal high-performance computing research, development, networking, and other activities; (2) establish Program Component Areas that implement such goals and identify the Grand Challenges (i.e., fundamental problems in science or engineering, with broad economic and scientific impact, whose solutions will require the application of high-performance computing resources) that the Program should address; and (3) develop and maintain a research, development, and deployment road map for the provision of high-performance computing systems.

Requires the advisory committee on high-performance computing to conduct periodic evaluations of the funding, management, coordination, implementation, and activities of the Program, and report at least once every two fiscal years to specified congressional committees.

Modifies provisions regarding responsibilities of the National Science Foundation, the National Aeronautics and Space Administration, the Secretary of Energy, the National Institute of Standards and Technology, the National Oceanic and Atmospheric Administration, and the Environmental Protection Agency.

Revises requirements for annual reports by requiring that such reports: (1) describe Program Component Areas, including any changes in the definition of or activities under such Areas and the reasons for such changes, and describe Grand Challenges supported under the Program; (2) describe the levels of Federal funding and the levels proposed for each Program Component Area; (3) describe the levels of Federal funding for each agency and department participating in the Program for each such Area; and (4) include an analysis of the extent to which the Program incorporates the recommendations of the advisory committee on high-performance computing. Eliminates the requirement for inclusion of reports on Department of Energy activities taken to carry out the National High-performance Computing Program.

Requires such advisory committee to: (1) provide the Director with an independent assessment of the balance between components of the Program, including funding levels for the Program Component Areas and whether the research and development undertaken pursuant to the Program is helping to maintain U.S. leadership in high-performance computing and networking; and (2) conduct periodic evaluations of the Program and report at least once every two fiscal years to specified congressional committees.

Requires the Office of Management and Budget (OMB) to identify each element of its high-performance computing activities which contributes directly to the Program Component Areas or benefits from the Program.

Repeals requirements under the Act for the National Research and Education Network and the Next Generation Internet.

Modifies provisions regarding responsibilities of the National Science Foundation (NSF), the National Aeronautics and Space Administration (NASA), the Department of Energy (DOE), the National Institute of Standards and Technology (NIST), the National Oceanic and Atmospheric Administration (NOAA), and the Environmental Protection Agency (EPA).

High-Performance Computing Revitalization Act of 2005 - Amends the High-performance Computing Act of 1991 to direct the President to implement a High-performance Computing Research and Development Program (current law provides for a National High-performance Computing Program) and revise program requirements.

Requires the Director of the Office of Science and Technology Policy to: (1) establish the goals and priorities for Federal high-performance computing research, development, networking, and other activities; (2) establish Program Component Areas that implement such goals and identify the Grand Challenges (i.e., fundamental problems in science or engineering, with broad economic and scientific impact, whose solutions will require the application of high-performance computing resources) that the Program should address; and (3) develop and maintain a research, development, and deployment road map for the provision of high-performance computing systems.
