U4.00001: General methods for computing atomic collision processes Invited Speaker: The general problem of electron-atom collisions within the framework of the non relativistic Schroedinger equation will be the subject of the presentation. The convergent close-coupling approach (CCC) will be discussed for a variety of targets and comparisons with experiment given. For the fundamental electron-hydrogen system, recent progress in computational methods including the CCC, exterior complex scaling (and variants), R-matrix method with pseudostates and time-dependent approaches will be reviewed. It will be demonstrated that this fundamental problem is now computationally solved for practically all scattering processes of experimental interest within the non-relativistic regime.

U4.00002: The SciDAC lattice gauge theory software program Invited Speaker: In the past few years many members of the US lattice gauge theory community have joined together to develop software to make writing parallel codes easier and to take full advantage of present and future supercomputer platforms. I will give an overview of the three levels of libraries developed for use in lattice gauge theory calculations. The first level is for communications and basic linear algebra routines. The second provides data parallel operations acting across the lattice. And the third contains full machine optimized versions of major computational kernels. [Preview Abstract] |

U4.00003: Lattice Computations of the CKM Matrix Invited Speaker: I discuss the progress being made in the determination of the elements of the Cabibbo-Kobayashi-Maskawa matrix from experimental data with unquenched improved staggered fermions. [Preview Abstract] |
