It defaults to 1 if not specified. How the field is used also depends on whether capacityKey is set. 1. If capacityKey is NOT set: allocationMultiplier multiplies the device count allocated to the claim. a. A DRA driver representing each CPU core as a device would have {ResourceName: \"cpu\", allocationMultiplier: \"2\"} in its nodeAllocatableResourceMappings. If 4 devices are allocated to the claim, 4 2 CPUs would be considered as allocated and subtracted from the node's capacity. b. A GPU device that needs additional node memory per GPU allocation would have {ResourceName: \"memory\", allocationMultiplier: \"2Gi\"}. Each allocated GPU device instance of this type will account for 2Gi of memory. 2. If capacityKey IS set: allocationMultiplier is multiplied by the amount of that capacity consumed. The final node allocatable resource amount is consumedCapacity[capacityKey] allocationMultiplier. For example, if a Device's capacity \"dra.example.com/cores\" is consumed, and each \"core\" provides 2 \"cpu\"s, the mapping would be: {ResourceName: \"cpu\", capacityKey: \"dra.example.com/cores\", allocationMultiplier: \"2\"}. If a claim consumes 8 \"dra.example.com/cores\", the CPU footprint is 8 2 = 16. capacityKeystring CapacityKey references a capacity name defined as a key in the spec.devices[].capacity map. When this field is set, the value associated with this key in the status.allocation.devices.results[].consumedCapacity map (for a specific claim allocation) determines the base quantity for the node allocatable resource. If allocationMultiplier is also set, it is multiplied with the base quantity. For example, if spec.devices[].capacity has an entry \"dra.example.com/memory\": \"128Gi\", and this field is set to \"dra.example.com/memory\", then for a claim allocation that consumes { \"dra.example.com/memory\": \"4Gi\" } the base quantity for the node allocatable resource mapping will be \"4Gi\", and allocationMultiplier should be omitted or set to \"1\".\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
