Allocate 910B3 slice

To allocate a certain size of device memory, assign huawei.com/Ascend910B3-memory alongside huawei.com/Ascend910B3.

apiVersion: v1
kind: Pod
metadata:
  name: ascend910b-job
spec:
  runtimeClassName: ascend
  containers:
    - name: ubuntu-container
      image: ascendhub.huawei.com/public-ascendhub/ascend-mindspore:23.0.RC3-centos7
      command: ["bash", "-c", "sleep 86400"]
      resources:
        limits:
          huawei.com/Ascend910B3: 1 # requesting 1 NPU
          huawei.com/Ascend910B3-memory: 2000 # Request 2000 MiB of device memory

note

With the default 910B3 templates, this 2000 MiB request selects vir05_1c_16g, which provides 16384 MiB of memory and 5 AI cores. Memory and compute are determined by the selected template.

Select Device by UUID

You can specify which Huawei Ascend devices a pod uses or excludes by using annotations:

apiVersion: v1
kind: Pod
metadata:
  name: ascend-pod
  annotations:
    # Use specific Huawei Ascend devices (comma-separated list)
    hami.io/use-Ascend910B3-uuid: "device-uuid-1,device-uuid-2"
    # Or exclude specific Huawei Ascend devices (comma-separated list)
    hami.io/no-use-Ascend910B3-uuid: "device-uuid-3,device-uuid-4"
