The NVIDIA GPU Device Plugin v0.15.0 release includes the following major changes:

Consolidated the NVIDIA GPU Device Plugin and NVIDIA GPU Feature Discovery repositories

Since the NVIDIA GPU Device Plugin and GPU Feature Discovery (GFD) components are often used together, we have consolidated the repositories. The primary goal was to streamline the development and release process and functionality remains unchanged. The user facing changes are as follows:

  • The two components will use the same version, meaning that the GFD version jumps from v0.8.2 to v0.15.0.
  • The two components use the same container image, meaning that instead of nvcr.io/nvidia/gpu-feature-discovery is to be used nvcr.io/nvidia/k8s-device-plugin. Note that this may mean that the gpu-feature-discovery command needs to be explicitly specified.

In order to facilitate the transition for users that rely on a standalone GFD deployment, this release includes a gpu-feature-discovery helm chart in the device plugin helm repository.

Added experimental support for GPU partitioning using MPS.

This release of the NVIDIA GPU Device Plugin includes experiemental support for GPU sharing using CUDA MPS. Feedback on this feature is appreciated.

This functionality is not production ready and includes a number of known issues including:

  • The device plugin may show as started before it is ready to allocate shared GPUs while waiting for the CUDA MPS control daemon to come online.
  • There is no synchronization between the CUDA MPS control daemon and the GPU Device Plugin under restarts or configuration changes. This means that workloads may crash if they lose access to shared resources controlled by the CUDA MPS control daemon.
  • MPS is only supported for full GPUs.
  • It is not possible to "combine" MPS GPU requests to allow for access to more memory by a single container.

Deprecation Notice

The following table shows a set of new CUDA driver and runtime version labels and their existing equivalents. The existing labels should be considered deprecated and will be removed in a future release.

New Label Deprecated Label

Full Changelog: v0.14.0...v0.15.0

Changes since v0.15.0-rc.2

  • Moved nvidia-device-plugin.yml static deployment at the root of the repository to deployments/static/nvidia-device-plugin.yml.
  • Simplify PCI device clases in NFD worker configuration.
  • Update CUDA base image version to 12.4.1.
  • Switch to Ubuntu22.04-based CUDA image for default image.
  • Add new CUDA driver and runtime version labels to align with other NFD version labels.
  • Update NFD dependency to v0.15.3.

v0.15.0-rc.2

  • Bump CUDA base image version to 12.3.2
  • Add cdi-cri device list strategy. This uses the CDIDevices CRI field to request CDI devices instead of annotations.
  • Set MPS memory limit by device index and not device UUID. This is a workaround for an issue where
    these limits are not applied for devices if set by UUID.
  • Update MPS sharing to disallow requests for multiple devices if MPS sharing is configured.
  • Set mps device memory limit by index.
  • Explicitly set sharing.mps.failRequestsGreaterThanOne = true.
  • Run tail -f for each MPS daemon to output logs.
  • Enforce replica limits for MPS sharing.

v0.15.0-rc.1

  • Import GPU Feature Discovery into the GPU Device Plugin repo. This means that the same version and container image is used for both components.
  • Add tooling to create a kind cluster for local development and testing.
  • Update go-gpuallocator dependency to migrate away from the deprecated gpu-monitoring-tools NVML bindings.
  • Remove legacyDaemonsetAPI config option. This was only required for k8s versions < 1.16.
  • Add support for MPS sharing.
  • Bump CUDA base image version to 12.3.1
