#gpu-clusters#cluster-management#production-readytogether-gpu-clusterstogether aislurmgpu
New production-grade features for GPU clusters: node repair, OIDC, and improved Slurm reliability.
30-Second TL;DR
What Changed
Implemented passive health checks and automated node repair
Why It Matters
These features reduce downtime and operational overhead for teams running large-scale training jobs. Improved cluster management ensures more stable and predictable performance for production AI workloads.
What To Do Next
Configure your cluster's OIDC settings and startup scripts to automate node initialization and improve security posture.

Enhanced Key Takeaways
- •Together AI's passive health checks utilize real-time telemetry to detect silent GPU failures, such as bit flips or interconnect errors, before they cause job crashes.
- •The automated node repair system integrates with the cluster orchestrator to automatically cordon and drain faulty nodes, reducing manual intervention by site reliability engineers.
- •Enhanced Slurm integration includes custom prolog and epilog scripts that ensure environment consistency across heterogeneous GPU clusters.
- •OIDC (OpenID Connect) support enables integration with enterprise identity providers like Okta or Azure AD, facilitating fine-grained access control for multi-tenant GPU environments.
- •The startup script functionality allows users to inject custom container configurations and environment variables at the node level, accelerating the deployment of large-scale distributed training jobs.

Technical Deep Dive
- Passive health monitoring architecture leverages NVIDIA DCGM (Data Center GPU Manager) to track ECC errors, thermal throttling, and PCIe link integrity.
- Slurm integration utilizes custom GRES (Generic Resource Scheduling) plugins to expose specific GPU topology information to the scheduler.
- Automated node repair workflow triggers a sequence of diagnostic tests (e.g., CUDA diagnostic kernels) before marking a node as healthy for job re-entry.
- OIDC implementation follows the OAuth 2.0 authorization code flow, allowing for short-lived token-based authentication for cluster API access.
Future ImplicationsAI analysis grounded in cited sources
Together AI will achieve 99.99% cluster uptime for large-scale training jobs by 2027.
The shift toward automated self-healing infrastructure significantly reduces the mean time to recovery (MTTR) for common hardware-related job failures.
The company will transition toward a fully serverless GPU orchestration model.
By abstracting node management and health checks, Together AI is positioning its infrastructure to handle workloads that require minimal user-side cluster configuration.
