WSL 2 GPU Support for Docker Desktop on NVIDIA GPUs

This post was originally published on this site

It’s been a year since Ben wrote about Nvidia support on Docker Desktop. At that time, it was necessary to take part in the Windows Insider program, use Beta CUDA drivers, and use a Docker Desktop tech preview build. Today, everything has  changed:

  • On the OS side, Windows 11 users can now enable their GPU without participating in  the Windows Insider program. Windows 10 users still need to register.
  • Nvidia CUDA drivers have been released.
  • Last, the GPU support has been merged in Docker Desktop (in fact since version 3.1).

Nvidia used the term near-native to describe the performance to be expected.

Where to find the Docker images

Base Docker images are hosted at https://hub.docker.com/r/nvidia/cuda. The original project is located at https://gitlab.com/nvidia/container-images/cuda.

What they contain

The nvidia-smi utility allows users to query information on the accessible devices.

$ docker run -it --gpus=all --rm nvidia/cuda:11.4.2-base-ubuntu20.04 nvidia-smi

The dmon function of nvidia-smi allows monitoring the GPU parameters :

$ docker exec -ti $(docker ps -ql) bash
[email protected]:/src# nvidia-smi dmon
# gpu   pwr gtemp mtemp    sm   mem   enc   dec  mclk  pclk
# Idx     W     C     C     %     %     %     %   MHz   MHz
    0    29    69     -     -     -     0     0  4996  1845
    0    30    69     -     -     -     0     0  4995  1844

The nbody utility is a CUDA sample that provides a benchmarking mode.

$ docker run -it --gpus=all --rm nvcr.io/nvidia/k8s/cuda-sample:nbody nbody -benchmark
...
> 1 Devices used for simulation
GPU Device 0: "Turing" with compute capability 7.5

> Compute 7.5 CUDA device: [NVIDIA GeForce GTX 1650 Ti]
16384 bodies, total time for 10 iterations: 25.958 ms
= 103.410 billion interactions per second
= 2068.205 single-precision GFLOP/s at 20 flops per interaction

Quick comparison to a CPU suggest a different order of magnitude of performance. GPU is 2000 times faster:

> Simulation with CPU
4096 bodies, total time for 10 iterations: 3221.642 ms
= 0.052 billion interactions per second
= 1.042 single-precision GFLOP/s at 20 flops per interaction

What can you do with a paravirtualized GPU?

Run cryptographic tools

Using a GPU is of course useful when operations can be heavily parallelized. That’s the case for hash analysis. dizcza hosted its nvidia-docker based images of hashcat on Docker hub. This image magically works on Docker Desktop!

$ docker run -it --gpus=all --rm dizcza/docker-hashcat //bin/bash
[email protected]:~# hashcat -I
hashcat (v6.2.3) starting in backend information mode

clGetPlatformIDs(): CL_PLATFORM_NOT_FOUND_KHR

Draw fractals

The project at https://github.com/jameswmccarty/CUDA-Fractal-Flames uses CUDA for generating fractals. There are two steps to build and run on Linux. Let’s see if we can have it running on Docker Desktop. A simple Dockerfile with nothing fancy helps for that.

# syntax = docker/dockerfile:1.3-labs
FROM nvidia/cuda:11.4.2-base-ubuntu20.04
RUN apt -y update
RUN DEBIAN_FRONTEND=noninteractive apt -yq install git nano libtiff-dev cuda-toolkit-11-4
RUN git clone --depth 1 https://github.com/jameswmccarty/CUDA-Fractal-Flames /src
WORKDIR /src
RUN sed 's/4736/1024/' -i fractal_cuda.cu # Make the generated image smaller
RUN make

And then we can build and run:

$ docker build . -t cudafractal
$ docker run --gpus=all -ti --rm -v ${PWD}:/tmp/ cudafractal ./fractal -n 15 -c test.coeff -m -15 -M 15 -l -15 -L 15

Note that the --gpus=all is only available to the run command. It’s not possible to add GPU intensive steps during the build.

Here’s an example image:

Machine learning

Well really, looking at GPU usage without looking at machine learning would be a miss. The tensorflow:latest-gpu image can take advantage of the GPU in Docker Desktop. I will simply point you to Anca’s blog earlier this year. She described a tensorflow example and deployed it in the cloud: https://www.docker.com/blog/deploy-gpu-accelerated-applications-on-amazon-ecs-with-docker-compose/

Conclusion: What are the benefits for developers? 

At Docker, we want to provide a turn key solution for developers to execute their workflows seamlessly:

  • With Docker Desktop, developers can run their code locally and deploy to the infrastructure of their choice.
  • We provide support in the issue tracker https://github.com/docker/for-win
  • Download the latest version of Docker Desktop now.
