support for Intel® Iris® Plus Graphics 640

[Saidani__Tarik]

Hi,

Is DPC++ supported on Intel® Iris® Plus Graphics 640?

When I run the following code:

#include <iostream>
#include <CL/sycl.hpp>

int main()
{

    cl::sycl::queue q(cl::sycl::gpu_selector{});

    auto device = q.get_device();

    std::cout << "device name is: " << device.get_info<cl::sycl::info::device::name>() << std::endl;

}

I get

terminate called after throwing an instance of 'cl::sycl::runtime_error'

  what():  No device of requested type available. 0 (CL_SUCCESS)

Aborted

Hi Tarik,

Please could you send output of "lspci" command for more details. 

Best regards,

Hi Jyotsna,

Just to be more specific I'm trying to run the program from within a intel/oneapi-hpckit Docker container. The reason being that I'm running it from my MacBook Pro (13-inch, 2017). There is no MacOS package for intel oneAPI at the moment, so that's the workaround I found. From the lspci output (see below) I can tell that the GPU is not detected in the container. Do you have any idea of a Docker run option that makes the GPU driver available ?

Many Thanks,

Tarik

Hi Tarik,

The docker run option  "--device=/dev/dri" enables the GPU(if available) as mentioned in the Get Started with the Intel® oneAPI Toolkits for Linux* . 

Let us know if you still see the issue.
