Multigrid methods with space-time concurrency
We consider the comparison of multigrid methods for parabolic partial differential equations that allow space-time concurrency. With current trends in computer architectures leading towards systems with more, but not faster, processors, space-time concurrency is crucial for speeding up time-integration simulations. In contrast, traditional time-integration techniques impose serious limitations ...
متن کاملTitle: Multigrid Methods Multigrid Methods Synonyms
Multigrid (MG) methods are used to approximate solutions to elliptic partial differential equations (PDEs) by iteratively improving the solution through a sequence of coarser discretizations or grids. The methodology has been developed and extended since the 1970’s to also target more general PDEs and systems of algebraic equations. A typical approach consists of a series of refinements or grid...
متن کاملMultigrid Methods
In this paper we present parallel solvers for large linear systems arising from the finite–element discretization of three–dimensional groundwater flow problems. We have tested our parallel implementations on the Intel Paragon XP/S 150 supercomputer using up to 1024 parallel processors. Our solvers are based on multigrid and Krylov subspace methods. Our goal is to combine powerful algorithms an...
متن کاملProbing foamy spacetime with Variational Methods
A one-loop correction of the quasilocal energy in the Schwarzschild background, with flat space as a reference metric, is performed by means of a variational procedure in the Hamiltonian framework. We examine the graviton sector in momentum space, in the lowest possible state. An application to the black hole pair creation via the Casimir energy is presented. Implications on the foam-like scena...
متن کاملMultigrid methods with Powell-Sabin splines
We present a multigrid algorithm for the solution of the linear systems that arise from a finite element discretization of second order elliptic partial differential equations with Powell-Sabin splines. We show that the method yields a uniform convergence independent of the mesh size.
