Parallel Performance Comparison of Three Direct Separable Elliptic Solvers
The parallel properties of three fast direct solution methods for linear systems with separable block tridiagonal matrices and a related C/MPI code are studied. Fast algorithm for separation of variables and two variants of the generalized marching algorithm are first summarized. The results from numerical tests performed on two coarse-grained parallel architectures are then reported. Th
