Allocate device memory

To allocate a percentage of device memory, specify resources such as cambricon.com/mlu.smlu.vmemory.

This field is optional. Each unit of cambricon.com/mlu.smlu.vmemory represents 1% of the device's total memory.

resources:
  limits:
    cambricon.com/vmlu: 1 # requesting 1 MLU
    cambricon.com/mlu.smlu.vmemory: "20" # Each MLU contains 20% device memory

warning

Set cambricon.com/mlu.smlu.vmemory as a plain integer (here, a percentage from 1 to 100), not a Kubernetes quantity. A suffixed value such as 16Gi is parsed as its byte count (about 17 billion), which overflows HAMi's 32-bit memory field and is silently truncated, often to 0. A zero memory request passes the scheduler's memory check unconditionally, so the pod can be placed on an MLU that is already full and then fails with out-of-memory errors at runtime. Use the integer form shown above (for example 20).

note

Depending on the parameters of cambricon-device-plugin, resource name can be cambricon.com/mlu370.smlu.vmemory or other types.
