Any update here? |

Check for any update |

Yes, OpenCL is a crucial feature. We're putting together a native Linux box for testing next week due to this. |
|
This would be wonderful for my team. We have considered rewriting everything in cuda, but that has major downsides. Until OpenCL support is released, we are stuck dual-booting. |

In theory OpenCL/WSL2 may now work for Intel Integrated Graphics GPUs: https://devblogs.microsoft.com/commandline/oneapi-l0-openvino-and-opencl-coming-to-the-windows-subsystem-for-linux-for-intel-gpus/ Trying a few days ago, I didn't see any CPU platforms get registered (I am on AMD for CPU) nor any GPU (I am on Nvidia for GPU) |
|
any info about whether NVIDIA GPU computing is planned to be supported for OpenCL? |
|
Any new info a year later? |
Better late than never, right? |

same issue when trying to run a boost example program |

I should have checked this before wasting a whole day trying to get it to work ... still waiting |

I found the solution, as it is going to be usual from now on, by asking ChatGPT. To set up OpenCL on WSL, you can follow these general steps:
After completing these steps, you should be able to use OpenCL on WSL. Note that the specific steps and packages required may vary depending on the Linux distribution, GPU hardware, and OpenCL implementation you are using. |

@jorgevazquezperez is that proven working or a hallucination? |
|
Proven working. It is needed to note that I have only achieved it with the CPU, but I am in process to be able to do it with the GPU. I attach you a picture with the results and I will keep you updated with the GPU version (as I imagine that it is the one you all are looking forward to). If you need more info just tell me! PD: I am using python with the pyopencl library.

Yes, afaict CPU and integrated Intel GPU should work, but unclear if/how Nvidia |
|
It's about getting Nvidia OpenCL to work in WSL2, not CUDA Runtime or AMD HIP/ROCM, is that correct? Please accept my apology if I misunderstood earlier. I remember having CUDA and AMD running as OpenCL in WSL2 in the past. However, due to driver changes, I had to reinstall Nvidia, which resulted in it breaking. Below is my clinfo with the AMD platform running. Unfortunately, both my RX470 and RX580 died, and I don't have another AMD card to try and show the result. |
|
Yes, that is still not showing Nvidia <> opencl <> wsl2 |
|
Since NVIDIA OpenCL ICD is built on top of CUDA, it's a bit hard to understand why OpenCL/NVidia is not supported under WSL2 when CUDA is functional. Clearly it's not a technical issue but a commercial issue. Please correct me if i'm wrong. |
|
I manage to get Intel OpenCL working in WSL2, I think.

This issue is about Nvidia cards not being shown, not intel/amd |
The title of the issue is simply "No OpenCL platforms reported" - not "No NVidia OpenCL platforms reported" |
The issue is about Nvidia cards not being shown. |

Looks like an Intel cpu/GPU again ^^^^, so same status |

Has anyone gotten OpenCL working with Edit: If you use a recent enough version of Ubuntu (i used 24.04, which is bleeding edge), you can just (base) root@cfbb31c89f97:/# clinfo

@alex-ong I have it working in WSL2 Ubuntu 22.04 without pocl on a laptop with a 5800HS, but for the intel platforms to be detected I have to source the setvars.sh script from the Oneapi installation. I installed it a long time ago so I don't recall the details of how I installed it. But I don't remember having much trouble with it. |

I was able to run OpenCL on NVIDIA on WSL2 via PoCL I took the following steps:
1.1. Now you can run
Then run On successful build you can try if it works without installing Also My And some benchmark (i dont know what these numbers means, good or bad) |
|
@Bossach Now this looks promising! PoCL too seems to have come a long way since I last checked. I might give it a try at some point. |
This worked for me. I installed it but the arguments aren't passed by default if I do clinfo it works with the |

@joaomamede Alternatively, yo can put |

Thanks for your share! I follow your step and it almost successful. However, the clinfo told me that "unknown target CPU 'sm_89'". Here is my full output and full benchmark. clinfo: benchmark: |
|
@Tongzhao9417 You need newer version of LLVM/clang. (Just checked llvm-16 from debian repo have "sm_89" one) |
Sorry for late reply. I follow your step and it's worked for me. Cheers! |
|
I compiled POCL as decribed above and now Does POCL not support OpenCL 2.0 ? |
|
Absolute king. pocl-opencl-icd was the missing link for me. Ty, sir. |

I really appreciate for your brilliant solution! I want to ask one question to you and everyone who reacted to Bossach's comment and/or tried the solution (@husmen @joaomamede @Tongzhao9417 @olympichek @htao7 @kirse @kon332k): have you tried the PoCL verification tests for NIVIDIA GPU I basically followed Bossach's steps to install PoCL and now have cd ~/pocl-6.0/build # move to my `build` directory
../tools/scripts/run_cuda_tests
# For rerunning the failed tests:
../tools/scripts/run_cuda_tests --rerun-failed --output-on-failureFailed tests were: The following tests FAILED:
4 - kernel/test_as_type_loopvec (Failed)
166 - regression/clSetKernelArg_overwriting_the_previous_kernel's_args_loopvec (Failed)
208 - runtime/test_device_address (SEGFAULT)
209 - runtime/test_svm (SEGFAULT)
Errors while running CTestIf anybody has conducted the verification test, could you please tell us whether you pass all tests or which tests you miss? It would be also very helpful if you could tell us about the runtime environment and settings, and configurations for PoCL installation. I opend an issue on PoCL's repo |

Windows Build Number
21382.1
WSL Version
Kernel Version
5.10.16.3
Distro Version
Ubuntu 20.04
Other Software
Inside WSL:
clinfo (for checking OpenCL platforms)
CUDA 11.3 (docker container runs with NVIDIA_DISABLE_REQUIRE=1, as it otherwise thinks it's running 11.0)
Docker 20.10.6, build 370c289 (with custom container)
nvidia-docker2 2.5.0-1
On Windows:
NVIDIA Graphics Driver for CUDA on WSL 470.14
Repro Steps
I installed the Nvidia drivers and docker as according to Nvidia's user guide
I am however running an older version of nvidia-docker2 (and dependencies) as according to a forum post here
Additionally, I have also installed the CUDA on WSL driver here
Steps:
Run clinfo (both in and outside of the Docker container)
Expected Behavior
clinfo should return the graphics card (in my case, GTX 970) as an OpenCL platform
Actual Behavior
clinfo reports 0 platforms available, both inside the container and just on WSL
Diagnostic Logs
cuda
nvidia-container-cli
glxinfo (from inside of container)
glxinfo (from WSL, outside of container)
wsl.etl
