在 MATLAB Online 中打开

Visual studio 2019

MATLAB 2022A

CUDA 11.6,When I test

coder.checkGpuInstall:
 
Compatible GPU           : PASSED 
CUDA Environment         : PASSED 
	Runtime   : PASSED 
	cuFFT     : PASSED

	cuBLAS    : PASSED 
cuDNN Environment        : FAILED (Unable to find the 'NVIDIA_CUDNN' environment variable. Set 'NVIDIA_CUDNN' to point to the root directory of a NVIDIA cuDNN installation.)

ans = 
  包含以下字段的 struct:
                 gpu: 1
                cuda: 1
               cudnn: 0
            tensorrt: 0
        basiccodegen: 0
       basiccodeexec: 0
         deepcodegen: 0
        deepcodeexec: 0
    tensorrtdatatype: 0
           profiling: 0

If I type in following codes in the commander line

gpuEnvObj = coder.gpuEnvConfig;
gpuEnvObj.GpuId = 0;
gpuEnvObj.BasicCodegen = 1;
gpuEnvObj.BasicCodeexec = 1;
results = coder.checkGpuInstall(gpuEnvObj)

the results is

Compatible GPU           : FAILED (Invalid CUDA device id: 1. Select a device id from the range 0:0.)

>>mex -setup
MEX 配置为使用 'Microsoft Visual C++ 2019 (C)' 以进行 C 语言编译。
要选择不同的 C 编译器，请从以下选项中选择一种命令:
Microsoft Visual C++ 2019 (C)  mex -setup:C:\Users\sunla\AppData\Roaming\MathWorks\MATLAB\R2022a\mex_C_win64.xml C
Microsoft Visual C++ 2022 (C)  mex -setup:D:\MATLAB2022a\bin\win64\mexopts\msvc2022.xml C
要选择不同的语言，请从以下选项中选择一种命令:
 mex -setup C++ 
 mex -setup FORTRAN

I looked throught the answers about 'emlc:compilationError' and "Invalid CUDA device", but no answer could figures out my problem.

what wrong with my gpu coder?

Hi Caiwei,

Could you also show us the error message in the report by clicking "View report"?

Thanks,

Chao

Hi Caiwei,

From the error message (Invalid CUDA device id: 1. Select a device id from the range 0:0.) it seems that the GpuId might have been 1?

Can you try running

>> gpuDeviceCount

and

>> gpuDeviceTable

to see if MATLAB is able to identify your gpu?

I think Cuda Toolkit 11.6 is not supported in your release. I am having difficulty finding the toolkit version that is supported: 11.0 for the release before yours.

You might have to enable forward compatibility https://www.mathworks.com/help/parallel-computing/parallel.gpu.enablecudaforwardcompatibility.html#mw_f28510a0-2087-45eb-84d4-80a0b1248e37

MATLAB2022a is proved to be qualified

See also https://www.mathworks.com/matlabcentral/answers/1825838-gpu-support-for-rtx-4090#comment_2430013 which indicates that R2021a is enough to generally use the RTX 3090, but that using GPU Coder could have problems, with a work-around suggestion there.
