Line 1: This page introduces how to check whether your NVIDIA GPU card is a CUDA enabled, and whether the latest NVIDIA drivers are installed. == CUDA Compatible Graphics == TUFLOW GPU requires an NVIDIA CUDA enabled GPU. To check if your computer has an NVIDA GPU and if it is CUDA enabled: <ol> <li> Right click on the Windows desktop.<br> [[File: GPU_Setup_001.png\|~~400px~~300px]]<br> <li> If you see “NVIDIA Control Panel” or “NVIDIA Display” in the pop up dialogue, the computer has an NVIDIA GPU. ~~<li> Change the directory location to the folder where nvidia-smi is located. Type '''<tt>cd C:\Program Files\NVIDIA Corporation\NVSMI</tt>''' into the DOS window and press enter.<br>~~ <li> Click on “NVIDIA Control Panel” or “NVIDIA Display” in the pop up dialogue. ~~[[File: Nvidia-smi 002.png\|700px]]<br>~~ <li> The GPU model should be displayed in the graphics card information.<br> ~~<li> Type '''<tt>nvidia-smi -l 10</tt>''' in the DOS window and press enter. This will instruct nvidia-smi to refresh every 10 seconds.<br>~~ [[File: ~~Nvidia-smi 003~~GPU_Setup_002.png\|~~700px~~600px]]<br> <li> Check to see if the graphics card is listed on the following website: <u>https://developer.nvidia.com/cuda-gpus</u> ~~<li> Review the nvidia-smi usage summary.<br>~~ [[File: Nvidia-smi 004.png\|700px]]<br>▼ </ol> == Updating NVIDIA Drivers == ~~== What to do if GPU utilisation = 0% when running TUFLOW HPC (when using the GPU Module) ==~~ It is likely that the NVIDIA drivers will need to be updated to the latest version as the drivers shipped with the computers are usually outdated. Windows 10 includes a Quick Edit mode option in the DOS window that can artificially pause TUFLOW simulations. The Quick edit mode is initiated if the curser clicks somewhere on the DOS window while a TUFLOW simulation is running. Quick Edit mode can be deactivated to avoid this issue. <ol> <li>Access the NVIDIA Driver Downloads (by following this link: <u>https://www.nvidia.com/Download/index.aspx</u>). <br> ~~<li> Right click the DOS window header. Select Properties. <br>~~ <li>Enter your GPU details, and click Search: <br> [[File: Nvidia-smi_005.png\|700px]]<br>▼ ▲[[File: ~~Nvidia-smi~~GPU Setup 004.~~png~~PNG\|~~700px~~500px]]<br> ~~<li> Uncheck Quick Edit Mode. This will turn it off for the current session. <br>~~ <li>Download Updated Driver and run Executable:<br> ~~[[File: Nvidia-smi_006.png\|400px]]<br>~~ ▲[[File: ~~Nvidia-smi_005~~GPU Setup 005.~~png~~PNG\|~~700px~~400px]]<br> ~~<li> Update the default DOS window properties so this becomes the default mode. Right click the DOS window header. Select Defaults. <br>~~ ~~[[File: Nvidia-smi_007.png\|700px]]<br>~~ ~~<li> Uncheck Quick Edit Mode, just like in the "Properties" dialog box . This will turn Quick Edit Mode off for all future sessions. <br>~~ </ol> ''NOTE: Even if not prompted by the system, a restart is recommended to ensure the new drivers are correctly detected prior to running any simulations.''
