    Yes and thank you for your help!


    I managed to reproduce this error the CUDA_ARCH number was to high


    To the second question:
    Yes it is running without compilation errors on only cpu and mpi.


    Hey Adrian,

    i checked my code in respect to the examples. But still I got this error where I am a bit clueless.

    Hello Adrian,

    Thank you for the quick reply.

    Indeed the space in the CUDA_ARCH definition was the gist of the matter.
    Still, my code isn’t running but the examples like venturi3d are now running on the GPU.

    All the best,
