News Release: RECLAMATION AWARDS $255,000 TO WINNERS OF RIVER MODELING PRIZE COMPETITION
Reclamation’s Sedimentation and River Hydraulics Group is looking for solutions to significantly improve the execution speed of numerical models that simulate hydraulics and sediment transport for rivers and reservoirs.
Reclamation has created robust and reliable numerical models for simulating river and reservoir processes. However, current model execution is limited to cases with relatively small time and spatial scales, and does not meet the ever-increasing demand for addressing questions related to large river systems and variable hydrology over decadal time periods. The current algebraic linear equation solver used in the models can take as much as 60-80% of the total execution speed and can only run on single-core PCs.
This prize competition has two phases. In Phase I, solvers will create a new linear equation sparse matrix solver (LESMS) that is at least as stable as Reclamation’s current solver and parallelized to run on multi-core PCs or GPU technology to meet speedup requirements. In Phase II, solvers will incorporate their solver into a version of Reclamation’s Two-Dimensional (2D) model and make the model run in multi-core parallel mode.
Reclamation is partnering with the Federal Highway Administration Office of Innovation Implementation – Resource Center, NASA Tournament Lab, and Freelancer.com on this competition.
To compete, solvers must register and submit their ideas no later than March 27, 2022, 11:59 PM ET. Please visit https://www.freelancer.com/reclamation/divide-and-conquer to learn more and ask your competition specific questions.Related Documents
