A 3-D Poisson solver based on conjugate gradients compared to standard iterative methods and its performance on vector computers
Report on the application of a conjugate gradient method (preconditioned by incomplete Crout) to the solution of a Helmholtz type (near Poisson) equation in 3-D. Compared to red-black SOR it is by a factor of 10 faster.
