clGetPlatformIDs return -1001

[feng__jean]

hi, I have two computers, and I list the details as below:

1. Inter Corporation HD Graphics 630(rev 04) && 8  Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz

2. Inter Corporation Haswell-ULT Integrated Graphics Controller  (rev 0b)  && 4  Intel(R) Core(TM) i7-4500U CPU @ 2.00GHz

and I have tried that i can install both openvino toolkit and opencl driver ok and update kernel to 4.14 ok, but I test official website's samples and my real codes, first computer(Inter Corporation HD Graphics 630(rev 04) && 8  Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz) works well, but to second computer( Inter Corporation Haswell-ULT Integrated Graphics Controller && 4  Intel(R) Core(TM) i7-4500U CPU @ 2.00GHz), it appears the same error "failed to create engine: clGetPlatformIDs error -1001"

so, there are 3 questions:

what's the difference with Haswell-ULT and HD Graphics 630(rev 04)

can I run code with gpu equipped with openvino toolkit(especially second computer)

how to fix "failed to create engine: clGetPlatformIDs error -1001"

thanks for your reply.

Dear feng, jean,

Please refer to the following online sources:

https://github.com/intel/compute-runtime/blob/master/README.md

https://ark.intel.com/content/www/us/en/ark.html

https://software.intel.com/en-us/openvino-toolkit/documentation/system-requirements

You should be able to find your answers by perusing the above online documents.

Please let me know if you have other questions. Your error seems to indicate that the GPU platform you're using is not supported.

Thanks,

Shubha

Hello feng, jean,

> what's the difference with Haswell-ULT and HD Graphics 630(rev 04)

The first system looks great as it has a supported GPU

https://ark.intel.com/content/www/us/en/ark/products/97128/intel-core-i7-7700-processor-8m-cache-up-to-4-20-ghz.html

Intel® HD Graphics 630

The second system has an unsupported GPU as it is not HD5** or higher.

Intel® HD Graphics 4400

> can I run code with gpu equipped with openvino toolkit(especially second computer)

Yes, you can on the first system. No you cannot on the second HD Graphics 4400 system as we found in other threads in this forum.

You can fix this by properly install OpenCL but still you will not be able to run clDNN (OpenVino -d GPU).

Cheers,
