A Problem of Running OpenCL Samples Codes for Intel(R) HD Graphics P4600 by the code-samples Downloaded from Intel

Jiawen_L_ · ‎01-04-2016

I used the OpenCL 1.2 sample codes downloaded from Intel official website(https://software.intel.com/en-us/intel-opencl-support/code-samples) to test the Intel Corporation Xeon E3-1200 v3 Processor Integrated Graphics Controller(Intel® HD Graphics P4600). I have set up the environment for the GPU successfully and the GPU information are as following codes. But when I run the Intel samples codes programs into the GPU, the following information shows up. Is the problem of the code?(It was not designed for the GPU because of the out of resource) If so, could you please offer me any tested sample codes for Intel® HD Graphics P4600 GPU? If the codes are no problem for Intel GPU, what should I do to run the Intel sample codes into the GPU successfully?

Hi Jiawen,

Could you please try to run these samples with smaller input sizes and see if they work for you?

Could you also please try the sample here https://software.intel.com/en-us/articles/sgemm-for-intel-processor-graphics (at the very bottom of the page is the download link)? It should be much more recent than the samples above.
