Parallel Krylov Solver for groundwater at the national and global scales
Publication type | artikel (tijdschrift)
Integrated high-resolution hydrological models are increasingly being used for the evaluation of water management in the field. Unfortunately, they require large amounts of memory and long run times. An efficient way of obtaining realistic run times and memory requirements is parallel computing, where the problem is divided between multiple processor cores. The new Parallel Krylov Solver (PKS) for the groundwater simulation code MODFLOW has been applied to the national Netherlands Hydrological Instrument (NHI) model and the global PCRaster Global Water Balance (PCR-GLOBWB) model. The Parallel Krylov Solver was developed in cooperation with the USGS, Utrecht University, Alterra and Delft University of Technology.
