Error running vector-add on NVIDIA GPU

Hello everyone!

This thread is related to https://software.intel.com/en-us/forums/oneapi-data-parallel-c-compiler/topic/850410?language=en-us&https=1 and I wanted to write there, but post was locked.

My problem is that when running vector-add example on NVIDIA Tesla P100 example I get error:

Command I run:

$ SYCL_DEVICE_TYPE=GPU SYCL_DEVICE_WHITE_LIST="" SYCL_DEVICE_ALLOWLIST="" ./vector-add

Device: Tesla P100-PCIE-12GB
terminate called after throwing an instance of 'cl::sycl::runtime_error'
what(): OpenCL API failed. OpenCL API returns: -34 (CL_INVALID_CONTEXT) -34 (CL_INVALID_CONTEXT)

Does someone have any about that?

Hi John,

Could you try running this sample on CPU and let us know if the issue persists?

What version of oneAPI base-toolkit are you using?

On CPU inteloneapi works just fine. Command I use to run on CPU:

$ SYCL_DEVICE_TYPE=CPU ./vector-add

Device: Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz
success

* My IntelOneApi version is beta04

Hi John,

Intel oneAPI currently doesn't support NVIDIA GPU's.

Hmmm... I checked here and I see that it should support NVIDIA GPU's:

Hi John,

Currently, Intel oneAPI basekit beta04 doesn't support Nvidia GPU's.

The link which you referred is Codeplay's distribution of oneAPI So you may need to install it separately and work on it.
