Our system configuration is as follows: CUDA Device: NVIDIA RTX A4000</p> <p>CUDA Toolkit Version: 12.2.0</p> <p>NVIDIA-SMI: 535.230.02</p> <p>Driver Version: 535.230.02</p> <p>CUDA Version: 12.2</p> <p>MATLAB Version: R2024b</p> <p>k-Wave Toolbox Version: 1.4</p> <p>k-Wave Toolbox Version (CUDA): 1.3 (CPP Linux Binaries)</p> <p>When we run the following command in MATLAB: sensor_data = kspaceFirstOrder2DG(kgrid, medium, source, sensor, input_args{:}, 'RecordMovie', false, 'DataCast', 'single');</p> <p>We encounter the following error message:<br /> ┌───────────────────────────────────────────────────────────────┐<br /> │ kspaceFirstOrder-CUDA v1.3 │<br /> ├───────────────────────────────────────────────────────────────┤<br /> │ Reading simulation configuration: Done │<br /> │ Selected GPU device id: Failed │<br /> └───────────────────────────────────────────────────────────────┘<br /> ┌───────────────────────────────────────────────────────────────┐<br /> │ !!!

If so, how can we resolve this issue?</p> <p>Thank you for your help! </p>
