Line 41:
* Click on “NVIDIA Control Panel” or “NVIDIA Display” in the pop up dialogue;
* The GPU model should be displayed in the graphics card information;
* Check to see if the graphics card is listed on the following website: <u>http://developer.nvidia.com/cuda-gpus</u>
On the NVIDA website each CUDA enabled graphics card has a “Compute Capability” listed. For cards with a compute capability of 1.2 or less, only the single precision version of the GPU Module can be utilised. However, benchmarking has indicated that the double precision version is NOT required and that the TUFLOW_iSP exe should be used for all GPU simulations. Extensive GPU hardware benchmarking has been undertaken to assist users who are upgrading hardware for TUFLOW modelling. Over 50 different hardware options have been tested for their speed performance. The results are provided on the <u>[[Hardware_Benchmarking | Hardware Benchmarking]]</u> page.
