GPU coder :basic Code Generation failed

Visual studio 2019

MATLAB 2022A

CUDA 11.6,When I test

coder.checkGpuInstall:

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

>>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

[Hariprasad Ravishankar]

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

I can run mexcuda and gpu mexw64 file. The fault occurs only when I use gpu coder

[zhou caiwei]

After I settle down the tensorrt and cudnn,the report becomes:

>>> gpuEnvObj = coder.gpuEnvConfig;
gpuEnvObj.GpuId = 0;
gpuEnvObj.DeepLibTarget = 'tensorrt';
gpuEnvObj.DeepCodegen = 1;
gpuEnvObj.DeepCodeexec = 1;
coder.checkGpuInstall(gpuEnvObj)

So, how do you think if I install MATLAB 2022b? could MATLAB 2022b release solve my problem?

[Walter Roberson]

I think the 3090 is too new to be supported in your release unless you turn on forward compatibility.

[zhou caiwei]

definitely yes! I downloaded MATLAB2022a and all the test passed!

[Walter Roberson]

@zhou caiwei

Do you perhaps means it works in R2022b ??

[zhou caiwei]

MATLAB2022a is proved to be qualified

[Walter Roberson]

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.

[zhou caiwei]

However, I'm not sure if other error would happens
