A Kubernetes device plugin for the Intel Neural Compute Stick 2 (NCS2) / Intel Movidius MyriadX
To directly install ncs2-device-plugin as a DaemonSet into the Kubernetes cluster:
$ kubectl apply -f https://raw.githubusercontent.com/adaptant-labs/ncs2-device-plugin/ncs2-device-plugin.yaml
Pods will be scheduled on any node with a feature.node.kubernetes.io/usb-ff_03e7_2485.present (provided by NFD) or
accelerators/ncs2 (provided by k8s-auto-labeller, in combination with NFD-based discovery) label set. These labels
can also be set manually on NCS2-capable nodes for simple deployments in order to enqueue the Pod.
Annotations are produced for the per-device full device name, allowing for different device types to be explicitly targeted, regardless of their insertion order into the system:
# For a single device
ncs2.intel.com/MYRIAD.name: Intel Movidius Myriad X VPU
# For multiple devices
ncs2.intel.com/MYRIAD.0.name: Intel Movidius Myriad X VPU
...
Node labels are produced for the number of devices and per-device optimization capabilities:
intel.com/ncs2=<number of NCS2 devices>
# For a single device
ncs2.intel.com/MYRIAD.FP16=true
# For multiple devices
ncs2.intel.com/MYRIAD.0.FP16=true
...
Node labels and annotations are reconciled on the node each time a USB device is added or removed from the system. This can be seen below:
