Deployment of a SYCL app to environment w/o SYCL compiler installed

[Lucie]

Hello Intel Community,

thanks for providing the oneAPI toolkits for programming with SYCL. I am currently using oneAPI Base Toolkit and developing a SYCL app using a GPU on Windows and I would like to deploy the app to an environment without the toolkit installed. I followed the instructions here Redistribute Libraries When Deploying Applications (intel.com) . However, there is a missing list for SYCL in section "Shared Library Dependencies for Device Offload". Is it incomplete or should my app work just with the dependencies listed by dumpbin? 

$ dumpbin /DEPENDENTS SYCLapp.exe
Microsoft (R) COFF/PE Dumper Version 14.00.24245.0

Dump of file SYCLapp.exe

File Type: EXECUTABLE IMAGE

Image has the following dependencies:
MSVCP140.dll
libmmd.dll
sycl6.dll
VCRUNTIME140.dll
api-ms-win-crt-stdio-l1-1-0.dll
api-ms-win-crt-heap-l1-1-0.dll
api-ms-win-crt-string-l1-1-0.dll
api-ms-win-crt-runtime-l1-1-0.dll
api-ms-win-crt-filesystem-l1-1-0.dll
api-ms-win-crt-math-l1-1-0.dll
api-ms-win-crt-locale-l1-1-0.dll
api-ms-win-crt-environment-l1-1-0.dll
KERNEL32.dll

I put libmmd.dll and sycl6.dll next to my executable, so it is not complaining about those. On a device with Intel Atom x6425E, I am getting the following error. Does it mean the platform is not supported or am I still missing some SYCL libraries?

Hi,

Thank you for posting in Intel Communities.

As per the Base toolkit system requirements, the Intel Atom x6425E processor is unsupported. Please refer to the system requirements link for the Intel oneAPI base toolkit.

https://www.intel.com/content/www/us/en/developer/articles/system-requirements/intel-oneapi-base-toolkit-system-requirements.html

The resolution of a DLL file is done by either setting the PATH environment variable or locating the DLL file in the same directory as the executable file.

Could you please try installing the Intel oneAPI DPC++/C++ Compiler Runtime package from the below link on the supported hardware and let us know the results?

Hello,

thank you for your response. 

Intel Atom is then not supported in general, correct? 

Does it mean I have to always ship the Intel oneAPI DPC++/C++ Compiler Runtime together with my SYCL app to deploy it on a (supported) hardware where compiler is not installed?

Cheers,

Lucie

Yes, you need to have the Intel oneAPI DPC++/C++ Compiler Runtime package to run the application.

Is your issue resolved? If yes, could you please confirm whether we can close this thread from our end?
