Functions

func GetGpuInfoForMetrics

func GetGpuInfoForMetrics(gpuConfig *cloudprovider.GpuConfig, availableGPUTypes map[string]struct{}, node *apiv1.Node, nodeGroup cloudprovider.NodeGroup) (gpuResource string, gpuType string)

GetGpuInfoForMetrics returns the name of the custom resource and the GPU used on the node or empty string if there's no GPU if the GPU type is unknown, "generic" is returned NOTE: current implementation is GKE/GCE-specific

func GetNodeGPUFromCloudProvider

func GetNodeGPUFromCloudProvider(provider cloudprovider.CloudProvider, node *apiv1.Node) *cloudprovider.GpuConfig

GetNodeGPUFromCloudProvider returns the GPU the node has. Returned GPU has the GPU label of the passed in cloud provider. If the node doesn't have a GPU, returns nil.

func NodeHasGpu

func NodeHasGpu(GPULabel string, node *apiv1.Node) bool

NodeHasGpu returns true if a given node has GPU hardware. The result will be true if there is hardware capability. It doesn't matter if the drivers are installed and GPU is ready to use.

func PodRequestsGpu

func PodRequestsGpu(pod *apiv1.Pod) bool

PodRequestsGpu returns true if a given pod has GPU request.
