Open CL error CL_DEVICE_NOT_AVAILABLE

[Udovydchenkov__Ilya]

Hi,

I am trying to run a code that requires Open CL, but I get an error "clCreateContext(): CL_DEVICE_NOT_AVAILABLE"

The CPUs are 2 quad core Intel Xeon X5482. Are these CPUs supported? Here is the OpenCL info. Thanks.

Hello IlyaU,

Thanks for the interest.

It doesn't look like that particular legacy Xeon product is supported by the 18.1 runtime in use. See supported processors for each CPU Runtime  in the release notes page.

That being said, if the code is not privileged...  it could be useful to see your OpenCL API setup code before and at the clCreateContext() function call.

Thanks,
