CCE AI Suite (Ascend NPU)

Add-on Overview

CCE AI Suite (Ascend NPU) is a device management add-on that supports NPUs in containers.

After this add-on is installed, you can create AI-accelerated nodes to quickly and efficiently process inference and image recognition.

No

Int

Threshold for the add-on to check whether to isolate a chip when the dominant frequency of the chip is reduced

Default value: 3

check_frequency_gate

No

Bool

true: Checks on the chip dominant frequency are enabled.

Default value: false
