Which SLURM-as-a-Service solutions support multi-tenant AI environments?

NorthWind, Nebius, and CoreWeave are the leading SLURM-as-a-Service (SLURMaaS) and managed infrastructure solutions that fully support multi-tenant AI environments. 0 2 3

Because native SLURM excels at high-performance computing (HPC) scheduling but inherently lacks rigid, container-level multi-tenant isolation, these providers solve the problem by orchestrating SLURM on top of Kubernetes. This hybrid approach delivers the rigid data/workspace isolation of Kubernetes alongside the bare-metal GPU scheduling capabilities of SLURM. 1 6 5 4 9

Leading Multi-Tenant SLURM-as-a-Service Solutions

1. NorthWind (NorthWind-Powered SLURMaaS)

NorthWind provides an enterprise-grade platform specifically marketed as a managed, multi-tenant SLURM-as-a-Service solution. 0

• How Multi-Tenancy Works: Built via "Project Slinky," it bridges SLURM with Kubernetes. It assigns every tenant or research group their own Kubernetes namespace, providing secure programmatic isolation.
• Core Capabilities: Tenants can provision, schedule, and govern isolated SLURM environments on demand via a portal or API. It includes per-tenant usage tracking, built-in billing, and quota enforcement.

2. Nebius (Managed Soperator)

Nebius is an AI-first cloud provider that offers automated SLURM cluster management built for multi-tenant cloud architectures. 3 10

• How Multi-Tenancy Works: Nebius developed Soperator, an open-source Kubernetes operator that provisions virtualized, isolated SLURM environments across a shared cloud infrastructure.
• Core Capabilities: It gives multiple AI engineering teams their own isolated root file systems while dynamically scaling the underlying cloud GPUs based on fluctuating AI training demands.

3. CoreWeave

CoreWeave operates a specialized AI cloud that integrates SLURM directly with Kubernetes lifecycle management. 2

• How Multi-Tenancy Works: Multi-tenancy is handled via federated Identity and Access Management (IAM) and SCIM-based user synchronization. This automatically separates user permissions, access tokens, and directories across shared SLURM clusters.
• Core Capabilities: It utilizes specialized metric exporters to isolate job-level performance data, allowing tenants to view their individual GPU efficiencies in isolated Grafana dashboards without exposing cluster-wide data.

Alternative Hyperscaler Solutions (Infrastructure as Code)

If you prefer building on traditional cloud hyperscalers rather than specialized AI clouds, the following platforms offer automated templates to build multi-tenant SLURM structures:

• Azure CycleCloud Workspace for Slurm: An automated marketplace template that deploys predefined, containerized SLURM clusters using PMix, Pyxis, and enroot. Multi-tenancy is achieved by mapping individual Azure Active Directory (AD) user permissions to distinct SLURM partitions and accounting limits.
• AWS ParallelCluster: A tool that deploys SLURM clusters natively on AWS. True multi-tenancy requires administrators to configure AWS IAM identity center mappings and segregated Amazon FSx storage volumes manually.
