    Container Service for Kubernetes:ack-ai-installer: Introduction and change log

    Last Updated:Mar 26, 2026

    ack-ai-installer is a collection of Device Plugins that enhances GPU scheduling capabilities in ACK Managed Cluster Pro Edition and ACK Edge Cluster Pro Edition. It works with ACK Scheduler — a unified scheduling system built on the Kubernetes Scheduling Framework extension — to support shared GPU scheduling and GPU topology-aware scheduling.

    Component overview

    ack-ai-installer includes the following sub-components. Each works with ACK Scheduler to extend GPU scheduling beyond the default exclusive GPU scheduling available in ACK Managed Cluster Pro Edition and ACK Edge Cluster Pro Edition.

    gpushare-device-plugin

    gpushare-device-plugin works with ACK Scheduler to enable shared GPU scheduling with sharing isolation. Multiple applications or processes share a single GPU card, improving resource utilization across the cluster.

    cgpu-installer

    cgpu-installer builds on shared GPU scheduling by integrating with cGPU, Alibaba Cloud's GPU container sharing technology. This adds:

    • GPU memory isolation: Different applications or processes are isolated from each other in GPU memory, preventing task interference.

    • GPU computing power isolation: Fine-grained allocation policies — average, preemption, and weight — control how computing power is distributed across containers.

    For installation methods and scenarios, see Manage the shared GPU scheduling component and Allocate computing power using shared GPU scheduling.

    gputopo-device-plugin

    gputopo-device-plugin enables GPU topology-aware scheduling. It selects the GPU combination on a node that provides the optimal training speed.

    For installation steps and scenarios, see GPU topology-aware scheduling.

    Usage notes

    • You can install ack-ai-installer only in ACK Managed Cluster Pro Edition and ACK Edge Cluster Pro Edition from the Cloud-native AI Suite page in the console.

    • ack-ai-installer is pre-installed in ACK Lingjun managed clusters.

    • For ack-ai-installer versions earlier than 1.12.0, cluster versions 1.18.8 and later are supported.

    • For ack-ai-installer versions 1.12.0 and later, only cluster versions 1.20 and later are supported.
