Allocate device memory

Allocate device memory by specifying the hygon.com/dcumem resource. This field is optional. Each unit of hygon.com/dcumem represents 1 MiB of device memory.

resources:
  limits:
    hygon.com/dcunum: 1 # requesting 1 DCU
    hygon.com/dcumem: 2000 # 2000 units x 1 MiB = 2000 MiB of device memory

warning

Set hygon.com/dcumem as a plain integer (a count of MiB), 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 a DCU that is already full and then fails with out-of-memory errors at runtime. Use the integer form shown above (for example 2000).
