Installs CUDA drivers to instance

Nvidia CUDA Layer

Installs the configured CUDA version with Nvidia drivers when supported GPU hardware is detected.


The following states are set by this layer:

  • cuda.supported

This state is set when supported GPU hardware is detected.

  • cuda.installed

This state is set once CUDA-related packages are installed and configured.


To use this layer, include it in the layer.yaml of a charm:

  - 'layer:nvidia-cuda'

Build and deploy the charm to a machine with Nvidia GPUs, e.g. instance-type=p2.xlarge on AWS or instance-type=Standard_NC6 on Azure.


The following runtime configuration options are available in this layer:

  • cuda-version

The cuda-repo package version to install. Defaults to 9.1.85-1.

  juju config <charm> cuda-version=9.1.85-1

Note: This layer constructs a major-minor string from this value and installs the corresponding cuda-x-y meta package (cuda-9-1 by default). This package will install the latest available dependencies in this series.

  • install-cuda

When True (the default), install and configure CUDA if capable hardware is present. Set this to False to prevent installation regardless of hardware support.

  juju config <charm> install-cuda=True


Disk Space

The packages installed by this layer require approximately 4GB of disk space. Specify a root-disk constraint if needed to ensure the machine has adequate disk space for installation. For example:

juju deploy <charm> --constraints "instance-type=p2.xlarge root-disk=16G"

Removing CUDA

When the install-cuda configuration option is set to True, required packages will be installed and the system will be configured to include CUDA paths. If install-cuda is subsequently set to False, the system configuration files created by this layer will be removed; however, the packages installed by this layer will remain on the system.

Restricted Networks

This layer installs packages from Configure proxies for Juju models in restricted network environments as needed. See Configuring Models for information about available proxy options.

(boolean) Install the CUDA binaries if capable hardware is present.
