TUFLOW Message
ERROR 2440 - Graphics card is incompatible with GPU solver or error in GPU initialisation.
Alternate Message
NA
Message Type
ERROR
Description
There has been an error when initialising the graphics card for a TUFLOW GPU simulation. This can occur for a number of reasons including:
- Insufficient GPU memory (GPU ERROR: Required memory exceeds available GPU memory)
- Cannot find any CUDA enabled devices (GPU ERROR: nDevices requested less than 1 or GPU ERROR: Non-cudaSuccess code returned)
- Compute capability is lower than required (GPU ERROR: Double precision requires compute capability of 1.3 or higher or GPU ERROR: Compute capability of 1.2 or higher is required.)
- Specified device ID does not exist (GPU ERROR: Cannot select device <requested device id>, must be in range 0 to <number of CUDA GPU Devices>)
Suggestions
The console window above the ERROR 2440 message should give more information on the reason the error is occurring. For example in the image below insufficient RAM is available.
If a CUDA compatible device is present in the computer, but not detected please check that you have the latest nVidia drivers installed.
