==Model 2==
ModelThe 22nd Model contains 228 Flood Modeller Pro nodes, a 5m resolution TUFLOW grid with a total of 570,214 cells. The model was run for 26 hours of model time with a 100 year boundary condition. The TUFLOW Classic model was run with a 1.25 second timestep. Table 2 shows the run times for model 2 when run with the same scenarios are model 1. The table shows that model run times can be up to 82% quicker when run on a GPU compared to TUFLOW Classic. Even when comparing the TUFLOW HPC GPU run time with the TUFLOW HPC run time when run utilising 8 cores, the simulation can be up to 74% quicker.

The impact of the TUFLOW HPC engine on a GPU card can be seen across a number of models as shown above.
The above simulation times were when running the models using 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 available in Flood Modeller 4.5 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. The above same models were run with Flood Modeller 4.5. The model results are presented in table x.
A further model was run which comprised of a Flood Modeller network together with a 2D domain and a X node ESTRY model.
Clearly demonstrates how TUFLOW HPC can leverage the technological improvements that are being made in terms of GPU cards and technology changes.
