Currently, in GEOS only the hypre interface is actively maintained. -For every multi-physics problem involving the solution of a coupled linear system, GEOS currently relies on a multigrid reduction preconditioning strategy available in hypre as presented by [@BUI:2020;@BUI:2021114111]. +For every multi-physics problem involving the solution of a coupled linear system, GEOS currently relies on a multigrid reduction preconditioning strategy available in hypre [@BUI:2020;@BUI:2021114111].

The RAJA performance portability layer provides [performance portable](https://performanceportability.org) kernel launching and wrappers for reductions, atomics, and local/shared memory to achieve performance on both CPU and GPU hardware.
