The Bureau of Reclamation (Reclamation) Sedimentation and River Hydraulics Group is looking for solutions to improve how quickly engineers can model flow hydraulics and sediment transport in rivers and reservoirs. Currently, engineers and scientists use Reclamation’s own incomplete lower-upper preconditioned conjugate gradient solver (ILU-CGS) to solve two- and three-dimensional models on PCs. Reclamation’s solver is very stable but because it is hard for it to be parallelized efficiently, it only runs on a single-core and therefore it is slow for large problems. As a result, the area or time period of a study must be limited, or the model can take so long to run that the data is no longer relevant. To solve this bottleneck, Reclamation is looking for a scalable parallelized or parallelizable LESMS that runs on a multi-core PC to replace Reclamation’s existing single-core ILU-CGS. Also, they want to replace their existing Sedimentation and River Hydraulics 2D (SRH-2D) model with a parallelized version that incorporates the newly developed LESMS.
