Unable to compile mexGPUExample.cu in Matlab R2023a

Dear Matlab community, I installed CUDA 11.8 and VS Community 2019, and the C++ and CUDA environments are identified by MATLAB.

Run the command:

mex -setup C++

And it shows:

MEX 配置为使用 'Microsoft Visual C++ 2019' 以进行 C++ 语言编译。

However, it was unable to pass the Basic Code Generation. When I run coder.checkGpuInstall command, it shows:

Compatible GPU           : PASSED 
CUDA Environment         : PASSED 
Runtime   : PASSED 
cuFFT     : PASSED 
cuSOLVER  : 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.)
Host Compiler            : PASSED 
Basic Code Generation    : FAILED (GPU code generation failed with the error 'emlc:compilationError'. View report for further information: View report)

I don't use neural networks, so I didn't install cuDNN.

The report said:

ninja: build stopped: subcommand failed.

At last, I run the command:

mexcuda -V mexGPUExample.cu

And this is what came out:

I tried

setenv("MW_NVCC_PATH","C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\bin")

to set the environment variables right, and it seems that MATLAB could recognize CUDA_PATH but still used its pre-installed nvcc compiler, which is located at "D:\MATLAB\sys\cuda\win64\cuda\bin\nvcc.exe". The compiling failed again.

Thank you for any help and suggestion.

At the same time, when I run the command:

mex -V mexGPUExample.cu

It gave this:

详细模式已开。
未标识 MEX 选项文件；将查找隐式选择内容。
错误使用 mex
未检测到支持的编译器。有关选项，请访问 https://www.mathworks.com/support/compilers。

which said no supported compiler is detected.

[伟]

And I have found a really funny thing. In my "nvcc_msvcpp2019_dynamic.xml" and "nvcc_msvcpp2019.xml" file, there is no version number at all.

For example, this is a part of my "nvcc_msvcpp2019_dynamic.xml":

<?xml version="1.0" encoding="UTF-8" ?>
<!-- Copyright 2020-2022 The MathWorks, Inc. -->
<!-- CUDA MEX options for MSVC 2019 -->
<config
Name="NVIDIA CUDA Compiler"
ShortName="nvcc"
HostCompiler="MSVCPP160"
Manufacturer="NVIDIA"
Version=""
Language="CUDA"
Priority="A"

The Version equals void.

In the same file, there is no version number after "release":

<cmdReturns name="$$\..\..\bin\nvcc --version | findstr /c:&quot;release &quot; > NUL && echo $$" />

Referring to mexcuda not finding CUDA 10.0 even after I specify it via setenv('MW​_NVCC_PATH​',...) - MATLAB Answers - MATLAB Central (mathworks.cn), normally it should be like this:

<cmdReturns name="$$\..\..\bin\nvcc --version | findstr /c:&quot;release 11.8 &quot; > NUL && echo $$" />

I just download MATLAB R2023a this morning, so I am pretty sure that I made no changes to these files.

You say you are unable to compile the example file using mexcuda, but I see no error message from that call. The verbose output seems to show you have been successful. What is the problem?

[伟]

And failed executing these two commands, "否" means no.

[Joss Knight]

Those warnings are all fine. I'm still having trouble working out what the actual error was. The verbose output shows that you got as far as invoking mex and successfully executing nvcc commands.

[Joss Knight]

It looks like the error may be a failure to delete temporary files, so you may for some reason not have permission to delete files from your Temp folder, which is odd. You may need to talk to your sysadmin.

[伟]

Dear Joss Knight,

Thank you for your time. The reason why I failed compling mexGPUExample.cu may be that the user's name is in Chinese, MATLAB or cuda may not support path name in Chinese. I will try to change the user's name to English and avoid any Chinese in the path name.

Thank you for your help again.

[Joss Knight]

I'd be disturbed if that was the reason since both NVIDIA and Microsoft have a significant Chinese customer base! I wonder, can you successfully call nvcc commands with your user directory on the path outside MATLAB? You could try copying the commands from the verbose output and pasting them into a system call.

Answer 1

[伟]

@Joss Knight, the problem is solved. I reset my computer system, and changed the user's name to English.The mexGPUExample.cu can now be compiled successfully.

mexcuda mexGPUExample.cu
使用 'NVIDIA CUDA Compiler' 编译。
MEX 已成功完成。

So I guess that was just the reason.

When compilng, some files are written in "C:\Users\xxxx\AppData\Local\Temp" where xxxx is the user's name. If xxxx is not in English, the compiling process will fail and no error will be reported.It looks like a unicode encoding problem.

[Joss Knight]

Hi 伟. Good to know. This does surprise me. I don't know whether this is a limitation of Visual Studio or of nvcc, but it almost certainly isn't a limitation of MEX. I'll follow up with the MEX team to find out.
