## Summary

Lambda announced on October 13, 2026, that it is working with NVIDIA to integrate the open-source **Run:ai scheduler** as a managed option in **Lambda Kubernetes Service (LKS)**. The scheduler, originally part of NVIDIA’s **Run:ai platform**, was open-sourced under the **Apache 2.0 license** in April 2025. Lambda has supported Run:ai since 2022 and aims to simplify adoption by embedding it directly into LKS, giving teams finer control over GPU allocation and sharing.

NVIDIA’s scheduler enables **GPU sharing**, **quota-based scheduling**, and **gang scheduling**, dynamically adjusting resources in real time. It supports workloads like debugging, distributed training, and evaluations by dividing GPU memory into fractions, allowing multiple jobs to run concurrently. Lambda also highlighted **auto-remediation** in LKS, which detects and fixes hardware faults like XID errors or degraded NVLink links, ensuring stable GPU operations. The integration is part of Lambda’s broader plan to offer a **managed library of schedulers**, including Slurm and Run:ai, as validated components rather than requiring manual setup.

## Key points

- Lambda and NVIDIA are integrating Run:ai scheduler into Lambda Kubernetes Service (LKS) as a managed option
- NVIDIA open-sourced Run:ai’s KAI scheduler in April 2025 under Apache 2.0 license for Kubernetes-native GPU scheduling
- LKS already includes auto-remediation for hardware faults and preinstalled NVIDIA GPU/Network Operators

## Why it matters

This integration streamlines GPU resource management for AI workloads on Kubernetes, reducing manual setup and improving efficiency for teams running distributed training or mixed workloads.
