Shear-Warp Deluxe: The Shear-Warp Algorithm Revisited
Despite continued advances in volume rendering technology, the Shear-Warp algorithm, although conceived as early as 1994, still remains the world’s fastest purely software-based volume rendering algorithm. The impressive speed of near double-digit framerates for moderately sized datasets, however, does come at the price of reduced image quality and memory consumption. In this paper, we present ...
متن کاملNew Methods in WARP
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”...
متن کاملBroadcast Time Warp
In many distributed computations it is necessary to ensure that the causal order in which events occur (a partial order) conforms to a total order that is derived from a correctness constraint on the computation. For example, the events of a distributed simulation must appear to be processed in simulation-time order. The Time Warp mechanism [Jeflerson 841 uses the notion of global virtual time ...
متن کاملThe Warp programming environment
This paper describes the environment for developing and executing Warp* programs. The center of the program development environment is a customized shell that ties together a compiler for the Warp array, the Warp run-time system, and a debugger. The compiler translates high-level language programs to microcode for the Warp machine. It achieves a high utilization of the computation power of the ...
متن کاملWarp Bridge Sampling
Bridge sampling, a general formulation of the acceptance ratio method in physics for computing free-energy difference, is an effective Monte Carlo method for computing normalizingconstantsof probabilitymodels.The methodwas originallyproposedfor cases where the probabilitymodels have overlappingsupport. Voter proposed the idea of shifting physical systems before applying the acceptance ratio met...
