WSL 2
Build 21327
Nvidia Driver 465.42
Nvidia toolkit 11.2
Linux version 5.4.91-microsoft-standard-WSL2

Error when running BlackScholes
CUDA error at …/…/common/inc/helper_cuda.h:779 code=35(cudaErrorInsufficientDriver) “cudaGetDeviceCount(&device_count)”

# Notes from the dev team Hey everyone we're filing this issue on ourselves t…o track the fact that GPU Compute support is unavailable in [preview build 21327](https://blogs.windows.com/windows-insider/2021/03/03/announcing-windows-10-insider-preview-build-21327/). This will affect any users who upgrade to this build but will not affect clean installations. We've identified a fix for this bug and have checked it in, and will need to wait for it to be validated internally before releasing it as part of the Windows Insiders program, we estimate that it will be available within the next couple of Insider builds. Thanks for your patience here! # Environment ```none Windows build number: 21327 Your Distribution version: All distros Whether the issue is on WSL 2 and/or WSL 1: WSL 2 ``` # Steps to reproduce Trying to use any Linux application that leverages the GPU on Windows will not work. Additionally /dev/dxg is not visible. # Expected behavior I should be able to use Linux applications that leverage the GPU. # Actual behavior The /dev/dxg device is not available in my Linux distros.

Hi, I am going through the steps to install NVIDIA HPC SDK and CUDA through WSL on my Windows 10 machine. When I try to find the WIP Dev Channel updates, I only see the 21327 Build version available. Since this will not work, is there a way to download the older versions of the Build?
