Parallel Block LU Factorisation in the Global Element Method Part 1: Share Memory Implementation

Lookup NU author(s): Professor Chris Phillips



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