Cannot use oneAPI cpu_selector but OpenCL is working in CPU.

RN1 — Thu, 02 Jul 2020 11:42:58 GMT

I can run any OpenCL program in the CPU and the GPU, but with oneAPI/sycl I cannot use the CPU.

I have used two sample programs (vector-add and simple-vector-inc) just modifying the `default_selector` to `cpu_selector`. They give me this error:

./vector-add-buffers Running on device: Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz Vector size: 10000 about to do q.submit about to do h.parallel_for An exception is caught for vector add. terminate called after throwing an instance of 'cl::sycl::runtime_error' what(): Native API failed. Native API returns: -34 (CL_INVALID_CONTEXT) -34 (CL_INVALID_CONTEXT) Aborted (core dumped)

What am I doing wrong?

I did some other tests, like trying to use different icl-loaders (/etc/OpenCL/vendors), but all Intel CPU fails with oneAPI/sycl.

If I execute on the GPU (`default_selector` or `gpu_selector`) it just runs successfully:

Running on device: Intel(R) Gen9 Vector size: 10000 about to do q.submit about to do h.parallel_for [0]: 0 + 0 = 0 [1]: 1 + 1 = 2 [2]: 2 + 2 = 4 ... [9999]: 9999 + 9999 = 19998 Vector add successfully completed on device.

Another question, is normal that the compilation phase (dpcpp -O2 -g ...) needs around 7s?

Hi Raul,

We can see that you are trying to execute "vector-add-buffers" from samples, but we don't know the exact reason why only you are getting this error. It seems that your specified context is not a valid OpenCL context.

So please give us more details about your OS and do the following updates in your code and give us outputs of them so that we can dig into it.

Add the below lines in your code.

std::cout << "Running on device: " << q.get_device().get_info<info::device::name>() << "\n" << q.get_context().get_platform().get_info<info::platform::name>() << "\n";

export SYCL_PI_TRACE=2
compile code and do $ ldd vector-add-buffers give us logs
execute the executable and give us the output.

Please give us all the details so that we can debug it.

Warm Regards,

Abhishek

Hi Abhishek!

I post here the details. Thanks for your support.
At least with this I can execute in the GPU, but in the other machine, I cannot even compile (https://community.intel.com/t5/Intel-oneAPI-Base-Toolkit/oneAPI-cannot-compile-sample-program-Support-for-Xeon-Phi-or/m-p/1189304#M292)

With the GPU:

Hi Raul,

Is it possible for you to change the underlying OS and test the same sample?

Because we tried on Ubuntu with Xeon(R) E-2176G and CPU selector it's working for us. We thought we will get some clue but it is difficult to get the exact problem.

Please update us.

Warm Regards,

Abhishek

Hello, Abhishek.

Finally, it is working although I needed to built all C++/libc system libraries manually and mock Ubuntu 18.04 profile env vars.
