SECTION 1. SHORT TITLE.

    This Act may be cited as ``Department of Energy Advanced Scientific 
Computing Act''.

SEC. 2. FINDINGS.

    The Congress finds the following:
            (1) The Department of Energy and its Office of Science 
        research programs has played an important role in the 
        development of high performance computing, networking, and 
        information technology. These capabilities have been readily 
        accessible to the U.S. scientific community for a diverse set 
        of grand challenge scientific computational problems. 
        Contributions by the Department include pioneering the concept 
        of remote, interactive access to supercomputers (developing the 
        first interactive operating system for supercomputers, 
        establishing the first national supercomputer center); 
        developing the mathematical foundations for high performance 
        computing with numerical linear algebra libraries used 
        worldwide; leading the transition to massively parallel 
        supercomputing by developing software to allow processors to 
        communicate with each other; and contributing to the 
        development of the Internet with software that dramatically 
        speeds up the transmission of messages.
            (2) The Department of Energy's Office of Science's 
        contributions to networking and information technology have 
        played a key role in its ability to accomplish its statutory 
        mission to promote the basic sciences critical to the Nation's 
        energy future through the development of remote access to its 
        shared computing and experimental facilities. Particular users 
        of the computing facilities have been high energy physicists 
        who model electromagnetic fields and beam dynamics in 
        accelerators, materials scientists who model and design 
        materials using computational techniques, chemists who model 
        the chemical processes involved in combustion, atmospheric 
        scientists who model global climate patterns, geologists who 
        model ground transport of fluids and waste, and biologists who 
        want to predict protein structures. Continued accomplishments 
        in these areas will be needed to continue to carry out future 
        DOE missions.
            (3) The Department of Energy has unique multi-disciplinary 
        facilities for advancing basic and applied science which 
        include the high energy and nuclear laboratories, neutron 
        sources and synchrotron facilities, and advanced computing and 
        communications facilities such as the National Energy Research 
        Scientific Computing Center, the Advanced Computing Research 
        Facilities, and the Energy Sciences Network. Each facility when 
        networked to share large amounts of scientific data will better 
        be able to advance the fundamental understanding in their 
        respective areas as well as the overall networking and 
        information technology infrastructure for the Nation.
            (4) Many challenges are associated with modeling complex 
        physical, chemical, and biological phenomena, especially on 
        massively parallel computers with peak speeds in hundreds of 
        teraflops (100 trillion arithmetic operations per second). 
        These challenges include the management and analysis of 
        petabyte-scale data sets. A program to address these challenges 
        will require multi-disciplinary collaborations between 
        theoretical and computational scientists, computer scientists, 
        and applied mathematicians at universities, national 
        laboratories, and industry. Such a program will enhance the 
        ability of DOE to meet its mission goals and advance the state 
        of the art for the U.S. economic and industrial base in the 
        fields of energy, geology, genetics, chemical processing, 
        electronics and transportation.
            (5) Solving the challenges facing the Department of Energy 
        in developing and using high-performance computing, networking, 
        and information technologies will be of immense value to the 
        Nation. Potential benefits include: reliable prediction of the 
        Earth's climate as well as the performance of energy systems; 
        understanding aging and fatigue effects in materials crucial to 
        energy and transportation systems; promoting energy-efficient 
        chemical production through improved chemical processes, 
        including rational catalyst design; predicting the structure 
        and functions of the proteins coded by DNA and their response 
        to chemical and radiation damage; designing more efficient 
        combustion systems; and understanding turbulent flow in plasmas 
        in energy and advanced materials applications.
