Flood Modeller-TUFLOW Benchmarking: Difference between revisions

The results of the benchmarking of model 1 are shown in Table 1. The implicit TUFLOW Classic scheme is comparable to the TUFLOW HPC when it is run on a couple of cores. This is due to the smaller timestep used in the explicit finite volume scheme which uses an adaptive timestep. As the number of cores used increases, the linked Flood Modeller Pro-TUFLOW HPC simulation is quicker, with run times reduced by up to 42%. A GPU card has a significant number of cores within it which can be utilized to undertake the 2D calculations. Running the same model on a GPU card leads to up to an 8388% reduction in run times compared to TUFLOW Classic (and up to 84% compared to TUFLOW HPC without utilising a GPU Card). This means that nearly 8 simulations can be run on a GPU card in the time that a single simulation could be run using TUFLOW Classic, highlighting the efficiencies of investing in hardware and also GPU modules. .
