Intel OpenCL SDK is installed on PC, 1 platform(OpenCL 2.1) and 2 devices are found. CL program can run for a long time on CPU device(m3-8100Y), but the same CL kernel can only run for about 20 minutes on GPU device(UHD Graphics 615), and block in clFinish function.

How can I make CL program work on the GPU device for a long time?

Detailed software and hardware information is as follows:

SDK: intel_sdk_for_opencl_applications_2020.0.245

OpenCL Platform: Intel(R) OpenCL, version:OpenCL 2.1

GPU: Intel(R) UHD Graphics 615

CPU: Intel(R) Core(TM) m3-8100Y CPU @ 1.10GHz

Hello There,

 

What do you mean by "long time"?

 

Are you trying to run a program you coded? why don't you tell us what are you trying to do?
