oneapi device selector fails in docker

[Tomasoni]

Hello all,

I've built a docker image with my own software and as a dependency intel oneapi basekit.

I run the image like this

```

docker run -it --rm --device=/dev/dri -v $(pwd)/advdiff:/qspcc/advdiff cosbi/qspcc-plus bash

```

to expose my gpu to the container ( I read about --device here https://www.intel.com/content/www/us/en/develop/documentation/get-started-with-intel-oneapi-base-linux/top/using-containers/using-containers-with-the-command-line.html )

but once in the container if I type

```

qspcc-server:/qspcc/advdiff> /opt/intel/compiler/latest/linux/bin/sycl-ls
[host:host:0] SYCL host platform, SYCL host device 1.2 [1.2]

```

it is showing nothing, neither the CPU.

this is the output of lspci on the host

```

$ lspci
00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Host Bridge/DRAM Registers (rev 07)
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor PCIe Controller (x16) (rev 07)
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)

```

Can anyone tell me howto expose my cpu/gpu to the docker container?

The host is ubuntu 20.04 LTS, the docker image debian 11.

thank you

Hi,

Thanks for reaching out to us.

Could you please provide us with the docker file and steps you have followed to build the docker file so that we can try it from our end?

>>I've built a docker image with my own software

Please let us know the detailes of the software you used to create docker image?

Thanks & Regards,

Noorjahan.

Hello and thank you for your answer.

The issue was related to the fact that I've not executed

. /opt/intel/setvars.sh

before calling sycl-ls

I was exporting the libraries manually through LD_LIBRARY_PATH

Now I understand that every time I want to do something with MKL I need to call setvars.

I still have a problem though.

The output now is

> /opt/intel/compiler/latest/linux/bin/sycl-ls
[opencl:acc:0] Intel(R) FPGA Emulation Platform for OpenCL(TM), Intel(R) FPGA Emulation Device 1.2 [2022.13.3.0.16_160000]
[opencl:cpu:1] Intel(R) OpenCL, Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz 3.0 [2022.13.3.0.16_160000]
[host:host:0] SYCL host platform, SYCL host device 1.2 [1.2]

But why my GPU is not there? What is this FPGA emulation?

I've installed intel-opencl-icd both in the docker container and in the host machine.

The same holds for another machine with an Intel Iris Xe Graphics in windows.

[opencl:acc:0] Intel(R) FPGA Emulation Platform for OpenCL(TM), Intel(R) FPGA Emulation Device 1.2 [2022.13.3.0.16_160000]

[host:host:0] SYCL host platform, SYCL host device 1.2 [1.2]

I attach a sample dockerfile without my program and other dependencies, but that behaves the same.

Thank you again for your help.

Hi,

Thanks for providing the details.

Could you please try using  --privileged option while running the docker file?

This flag will give all the capabilities to the container that a host can perform.

Command:

docker run -idt --privileged <image> bash

We have tried to run intel/oneapi-basekit docker image and are able to see GPU information in the container.

Please find the attached screenshot for more details:

Thanks & Regards,

Noorjahan.

Hello, thank you for your answer.

The result in the linux box with

```

docker run -it --rm --privileged --device=/dev/dri -v $(pwd)/advdiff:/qspcc/advdiff <IMAGE> bash

```

is the same.

```

[host:host:0] SYCL host platform, SYCL host device 1.2 [1.2]

```

This is the output of lspci in the host

```

```

In the other pc with an Intel Iris Xe Graphics in windows I run

```

docker run -it --privileged --rm -v ${PWD}\tests:/qspcc/tests <IMAGE> bash

```

and get the same

```

Hi,

We see that you did not install the Intel Graphics Driver in the Docker.

Please refer to the below link for more details to install the Graphics Driver and this docker example is for Ubuntu 20.4. (Line No: 42-45)

https://github.com/intel/oneapi-containers/blob/master/images/docker/basekit/Dockerfile.ubuntu-20.04

Please Install the graphics driver and let us know if you still face the same issue.

Thanks & Regards,

Noorjahan.

[NoorjahanSk_Intel]

Hi,

We haven't heard back from you. Could you please provide an update on your issue?

Thanks & Regards,

Noorjahan.

[NoorjahanSk_Intel]

Hi,

We have not heard back from you, so we will close this inquiry now. If you need further assistance, please post a new question.

Thanks & Regards,

Noorjahan.

[Tomasoni]

I'm sorry for the late reply, but I don't get e-mail updates.

I'll try installing drivers asap and let you know.

thanks.

[Tomasoni]

Hello again,

I checked my dockerfile and I installed intel-opencl-icd  I thought it would be sufficient for the driver installation (line 47 of my dockerfile)

I looked at your sample dockerfile but it is installing also dscpp and other dependencies I'm already installing later (line 106 of my dockerfile) which is the package name that I'm missing? maybe `intel-level-zero-gpu level-zero` ?

I don't think I need dev packages since I'm only compiling against oneapi, or am I wrong?

The reason why I don't install everything is just because I want to keep the docker as slim as possible.

Thank you.

Danilo

Thank you, now it works, I tried adding to the dockerfile

```

# repository to install Intel(R) GPU drivers
RUN curl -fsSL https://repositories.intel.com/graphics/intel-graphics.key | apt-key add -
RUN echo "deb [trusted=yes arch=amd64] https://repositories.intel.com/graphics/ubuntu focal main" > /etc/apt/sources.list.d/intel-graphics.list

```

and then in the apt-get command I installed

intel-opencl-icd intel-level-zero-gpu level-zero level-zero-dev

now the gpu is recognized:

```

thank you!
