Abstract

The Global Element Methods is a (spectral)numerical technique for solving elliptic and parabolic differential equations in two space dimensions. The solution, defined as a set of polynomial coeffieients, is obtained from a linear system of equations in which the coefficient matrix is block sparse. We describe a parallel LU decomposition of the matrix targeted at a local memory multiprocessor.
