ABSTRACT
In this paper parallel methods for solving large order linear equations, i.e. the Implicit Matrix Elimination (PIE) and Quadrant Interlocking Factorisation (WZ) methods are compared. Timings on a shared memory computer confirm the superiority of the new methods for both sequential and parallel implementations over the Gaussian Elimination and LU factorisation methods.
