| description |
In this work, it is presented a new parallel wavelet-
based algorithm for the Algebraic Multigrid
Method (PWAMG). A variation of the standard
parallel implementation of discrete wavelet
transforms is used in the construction of a hierarchy
of matrices and of intergrid transfer operators
for Algebraic Multigrid. The PWAMG
method has been tested as a parallel solver for
the two dimensional Poisson equation, for different
numbers of finite difference mesh nodes
and comparisons are made with the sequential
version of this method. |
