New Methods in WARP
نویسندگان
چکیده
The WARP[1] code is being developed and applied to simulate the creation and propagation of the high-current, space-charge dominated beams that are required for heavyion driven fusion energy (HIF). New methods and capabilities have recently been introduced into WARP, a multidimensional particle-in-cell code developed for the study of space-charge dominated beams. We describe: (a) a 2D3V “slice” model (WARPxy) with two novel capabilities: the optional use of 3D applied fields (which can be calculated using the WARP3d solver), and an “exact” treatment of a bent beam pipe, via coordinate transformations; (b) a multigrid fieldsolver which offers internal conductors in 2D and 3D; (c) serial optimizations for cache-based machines which yielded a 20-30% speedup; and (d) a Python interface which has been developed to give the full power of a scripting language user interface in both serial and parallel computing environments.

متن کاملApplications experience on Warp
The prototype Warp* machine at Carnegie Mellon is being used to develop new applications in magnetic resonance image processing, as a research tool in image texture analysis, and for scientific computing. In these areas, orders of magnitude speedup over conventional computers are being observed. These new applications build on our use of Warp for low level vision, which is the area for which th...
متن کاملPhylogenetic signals in morphometric data
Although many of the goals and concepts of qualitative morphological analysis and morphometrics are similar, systematists have largely rejected the use of morphometric methods in phylogenetic analysis on a variety of grounds. This review finds that (1) the concepts of a cladistic character and a morphometric variable are essentially identical, (2) morphometric methods can be instrumental in dis...
متن کاملNURBS Warps
Standard Free-Form Deformations (FFD) built upon tensor-product B-Splines have been proved useful to model the warp between two views of a deformable surface. In this paper, we show that the standard FFD is the affine projection of a threedimensional tensor-product B-Spline surface. We construct a new tensor-product warp relying on Non-Uniform Cubic B-Spline: the NURBS-Warp. We show that this n...
