Why does the MIKE software not find my GPU card?

If the GPU is not recognized by the MIKE software, it may be due to the following reasons:

#01 - An outdated GPU driver
An outdated GPU driver does not work with the given version of the MIKE software. Please try updating the driver via the NVIDIA download page 

Note: Some tools may report the GPU driver to be the latest even if it is not. Therefore, always check which driver version is installed by going to the device manager  - see example in Fig. 1 - the last 5 digits show the driver version -  e.g. in this case 398.36. Compare with the latest driver version provided in the NVIDIA download page

You may need to select the download type 'Game Ready Driver (GRD)' to get the latest driver 

#02 - MIKE software not supporting the GPU
For example, with MIKE Zero Release 2023 only NVIDIA GPUs of computation capability 6.0 or higher are supported. A list of GPUs and their  computation capability  is found in this page Your GPU Compute CapabilityAs NVIDIA plans to discontinue the support for several generations of GPU cards, we advise all our users to start upgrading to GPU cards with a computation capacity of 6.0 and above.

Note: The expiry date for the GPU option in the license file follows the SMA expiry date.

If the GPU has been successfully recognized by the MIKE software, then the “Parallelization” tab in the “Launch Settings” dialogue in the respective MIKE FM editor will look like example in Fig 2 (left). Otherwise, it will look like example in Fig. 2 (right)

Similarly in MIKE+, the user of GPU will be disabled if the GPU card has not been successfully recognized - see Fig. 3.
