Preconditioners With Low Memory Requirements for Higher-Order Finite-Element Method Applied to Solving Maxwell's Equations on Multicore CPUs and GPUs

This paper discusses two fast implementations of the conjugate gradient iterative method using a hierarchical multilevel preconditioner to solve the complex-valued, sparse systems obtained using the higher order finite-element method applied to the solution of the time-harmonic Maxwell equations. In...
