In this optional section we will run the model using TUFLOW HPC (Heavily Parallelised Compute). TUFLOW HPC can run between 10 and 100 times faster than TUFLOW Classic using NVidia Graphics Processing Units (GPU)(depending on the model configuration and hardware performance). The speed of HPC makes it exceptionally well suited to high resolution direct rainfall urban applications. Large models with over 1,000,000 2D cells that take days to run using TUFLOW Classic can take hours to complete using TUFLOW HPC with high performance GPU hardware! The presentation "Rapid and Accurate Stormwater Drainage Assessments Using GPU Technology" highlights some performance test results comparing TUFLOW Classic against TUFLOW HPC for high resolution direct rainfall urban 1D/2D applications. A pdf copy of the presentation is available from the [https://www.tuflow.com/Download/Presentations/2017/Huxley2017_IECA-SQ%20Conference_Brisbane_pdf.pdf TUFLOW Library]<br><br>
''Note: If you have not previously used TUFLOW HPC, we recommend completing Tutorial Module 1, 2 and 3 before attempting this tutorial. The preceding tutorials include important lessons specific to using HPC, particularly its adaptive timestep / unconditional stability and GPU Hardware. Please see [[HPC_Features_Archive | HPC Features Archive]] for more information on TUFLOW HPC features supported in the 2017 release.<br><br>
In order to use the HPC solver, we will need to perform the following steps:
