3. Basic Energy Sciences Theoretical Condensed Matter Physics Condensed Matter Physics & Materials Chemistry Team Materials Sciences and Engineering Division Materials and Engineering Physics: Dispersed Theory Structure and Composition of Materials: dynamic behavior of nanostructures; greater ability to treat inhomogeneous materials, esp. disorder; includes the effort on the constrained local moment model for spin dynamics. Mechanical Behavior of Materials and Radiation Effects: predict material behavior under exposure conditions (irradiation, temperature, and mechanical loading) that represent a significant extrapolation beyond our existing knowledge base. Physical Behavior of Materials: coupling of length scales from atomic to macroscopic; organic electronic materials --- charge and energy transfer, electronic structure calculation, exciton dynamics and transport, spin dynamics. Synthesis and Processing Science: fundamental understanding of mechanisms and processes to aid systematic design. Engineering Physics: multiplicity of scales; managing the explosion of data; an INCITE award occurred here.

Basic Energy Sciences Theoretical Condensed Matter Physics Condensed Matter Physics & Materials Chemistry Team Materials Sciences and Engineering Division Calculated state of 512 atoms from paramagnetic (high temperature) bcc iron. The variation of magnetic moment is given by the color scheme. Implementation of the fundamental approach requires intensive computing --- the code has won the top prize for computational efficiency --- but also the resolution of further subtle and difficult fundamental theoretical issues. The Heisenberg model, long used to describe the magnetic behavior of materials, is a model involving experimentally determined parameters. Recently, a fundamental theory has been formulated for which the Heisenberg model could be considered an approximation. Within this theory, the magnitude of the moments can change as they are rotated as illustrated in the figure. In addition to such new effects, the formalism also enables one to calculate and interpret the strengths of interaction. This will lead to further insights how materials arrange themselves to have magnetic moments and, equally important, how they avoid them. A major step forward towards understanding magnetic materials, this theory is extends Density Functional Theory and utilizes it in regimes where numerous aspects are still not well understood. Consequently, applying this theory will simultaneously enhance our understanding of magnetic materials and of the basic theory. It is also a non-trivial computational effort! ◄◄ Dynamics of Spins

5. Basic Energy Sciences Theoretical Condensed Matter Physics Condensed Matter Physics & Materials Chemistry Team Materials Sciences and Engineering Division INCITE Program The projects were selected under a new competitive program, entitled Innovative and Novel Computational Impact on Theory and Experiment (INCITE), announced last July by Energy Secretary Spencer Abraham. 52 proposals were submitted. Three awards amount to 10 percent of the total computing time available this year on NERSC's current IBM SP3. “Fluid Turbulence and Mixing at High Reynolds Number," led by P.K. Yeung (Georgia Tech.), was awarded 1,200,000 processor hours in the area of forced isotropic turbulence. The principal investigators have NSF grants but their INCITE activities are a part of the Engineering Physics activity.

Last year, over 3.35x10 6 processor hours were used on the IBM SP3 at the National Energy Research Supercomputer Center and ~1.6x10 6 IBM SP3 & SP4 processor hours helping evaluate computers at Oak Ridge National Laboratory. (The two machines involved will become a part of the production system this year.) At 45 repositories (account for PI and coworkers), MATSCI is the program with the largest “ population ” of users. Requests for time ran roughly 3 times the resources available this year BEFORE NEW, LARGE SPECIAL REQUESTS.
