This paper presents a new distributed simulation methodology for hierarchical Discrete Event System Specification(DEVS) models. The DEVS formalism provides a formal basis for specifying discrete event models in a modular, hierarchical form. For distributed simulation of DEVS models, a synchronization mechanism is required to control the advance of simulation clocks. The proposed methodology emp...

Pasting onto a deformable surfaces requires either a non-parametric warp or a high d.o.f global warp approximation. Previous works utilized techniques such as moving least squares or hierarchical big data to define a non-parametric mapping from an image to a known template. In this paper, I use Dense SIFT Flow to generate a dense pixel mapping which is used to warp regions from a mesh template ...

Silicon-on-insulator (SOI) wafers are nowadays being prominently used for the manufacture of new generation semiconductor devices. In order to maximize the device yield, the device industry is seeking SOI wafers that meet very stringent wafer specifications such as very low wafer bow and warp. An SOI wafer can undergo severe process-induced stresses during its manufacture leading to significant...

We have integrated the electron-cloud code POSINST [1] with WARP [2]–a 3-D parallel Particle-In-Cell accelerator code developed for Heavy Ion Inertial Fusion–so that the two can interoperate. Both codes are run in the same process, communicate through a Python interpreter (already used in WARP), and share certain key arrays (so far, particle positions and velocities). Currently, POSINST provide...

We assume familiarity with PDES (Fujimoto 1990), Adaptive synchronization algorithms have been proposed to improve upon conservative and optimistic algorithms. We present the first known analytical comparison of adaptive, o p t i ~ s t i c algorithms and Time Warp. We define a class of adaptive protocols, the asynchronous adaptive waiting protocols (AAWP’s) and identify several practical protoc...

This paper exemplifies the similarities in Time Warp and computer architecture concepts and terminology, and the continued trend for convergence of ideas in these two areas. Time Warp can provide a means to describe the complex mechanisms being used to allow the instruction execution window to be enlarged. Furthermore it can extend the current mechanisms, which do not scale, in a scaleable mann...
