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.
