Line 81:
The results from the benchmarking of the hydraulic runs, clearly shows the impact of running models on TUFLOW HPC compared to TUFLOW Classic, and in particular the significance of running TUFLOW HPC on a GPU to significantly reduce model run times. The results show that linked Flood Modeller-TUFLOW HPC run times are up to 8 times faster than TUFLOW Classic and up to 6 times faster than TUFLOW HPC when run on 8 CPU. Reducing model run times allows more efficiency by reducing the time taken to wait for simulations when various options are tested during the model build phase, increase productivity when running through the final design runs over a suite of return periods and durations and open up opportunities in terms of uncertainty analysis through Monte-Carlo type approaches which require a large number of simulations to be conducted.
The simulation times were when running the models using the latest release of Flood Modeller 4.4. Flood Modeller 4.4 although supporting TUFLOW HPC and GPU cards does not support the concurrent simulation of Flood Modeller Pro, TUFLOW HPC and TUFLOW’s 1D scheme, ESTRY. The ability to run all three simultaneously is scheduled to be available in the Flood Modeller 4.5 release which has been provided in a beta testing phase for this analysis. The ability to run Flood modeller Pro, TUFLOW 2D and TUFLOW 1D components allows the running of a fully integrated drainage models comprising open channels, 2D floodplains as well as 1-Dimensional pipe networks and their interaction with the surface as represented by the 2D domain
