Dynamic Adaptation for Grid Computing
As Grid architectures provide resources that uctuate, applications that should be run on such environments must be able to take into account the changes that may occur. This document describes how applications can be built from components that may dynamically adapt themselves. We propose a generic framework to help the developpers of such components. In the case of a component that encapsulates...
متن کاملAdaptation of Structured Grid for Supersonic and Transonic Flows
Two distinct redistribution grids - adaptation techniques, spring analogy and elliptic grid generator are applied to two-dimensional steady, inviscid, shocked flows, and the ability of each technique is examined and compared. Euler equations are solved base on Roe's Reimann solver approach to simulate supersonic flow around a sphere, transonic flow about an airfoil and supersonic flow in a symm...
متن کاملGrid-free Adaptive Semi-lagrangian Advection Using Radial Basis Functions
This paper proposes a new grid-free adaptive advection scheme. The resulting algorithm is a combination of the semi-Lagrangian method (SLM) and the grid-free radial basis function interpolation (RBF). The set of scattered interpolation nodes is subject to dynamic changes at run time: Based on a posteriori local error estimates, a self-adaptive local refinement and coarsening of the nodes serves...
متن کاملTracer-Particle Advection: Algorithm Components and Implementation Methods
Tracer-particles, massless particles that are advected throughout the flow domain, are an important factor in computational solutions. The utility of tracer-particles, which sample and report relevant solution data, is predicated upon an accurate advection algorithm. The objective of this research was to investigate the ability of existing techniques, physical-space and logical-space advection,...
متن کاملDynamic adaptation of parallel and distributed components on Grid environments
Wireless communication based applications always need adaptation techniques because the bandwidth and the resources of the network often change during the execution of an application. These applications are characterized by a low bandwidth, small data sets and low-end machines. At the opposite of the spectrum, Grid applications use powerful supercomputers, high bandwidth networks and process la...
