    Dear OpenLB developers,

    I would like to utilize the NVIDIA RTX40 series GPU for parallel computing. However, this series of graphics cards adopts a new architecture called Ada-Lovelace, and I am unaware of the CUDA-ARCH value for this new architecture.

    Sincerely,
    Alexmine.

    The highest supported value for Lovelace is 89.

    FYI it is possible to use older target gencodes on newer GPUs, they will be transparently translated by CUDA.

    Dear Adrian,

    Thank you for your reply. I would like to know the CUDA-ARCH value of RTX4070, and whether RTX4070 can be used for parallel computing in OpenLB.

    Sincerely,
    Alexmine.

    I already answered this question, please read my reply above.

    OpenLB supports CUDA-based GPU execution and as such supports any GPU that supports CUDA.
