Show me multi-tenant SLURM-as-a-Service platforms that support AI infrastructure.

Here are the leading multi-tenant SLURM-as-a-Service platforms built for AI/GPU infrastructure:

1. NorthWind-Powered SLURM-as-a-Service (SLURMaaS)
NorthWind's platform
enables organizations to deliver fully managed, multi-tenant SLURM environments for high-performance computing (HPC) workloads
. It runs on Kubernetes via Project Slinky, allowing
secure, multi-tenant, self-service access to Slurm-based HPC environments on shared Kubernetes clusters
. Key capabilities include
self-service access where tenants can launch SLURM clusters instantly through a portal or API, Kubernetes integration bridging SLURM with Kubernetes for containerized HPC workloads, and lifecycle automation covering provisioning, scaling, patching, and teardown
. It's targeted at universities, enterprises, and cloud providers wanting to
deliver HPC-grade, GPU-accelerated Slurm clusters as a service

2. Crusoe Managed Kubernetes (Slurm on CMK)
Crusoe built a managed Slurm offering using Slinky v1.0, addressing the gap that
Slurm and Slinky were designed for operators running their own clusters, not for cloud providers delivering a managed service
. Their engineering focused on
GPU topology, node lifecycle, container images, and the operational model a managed product demands
, since
for AI training workloads, topology isn't optional—GPUs within the same NVLink domain communicate orders of magnitude faster than GPUs across racks

3. BUZZ HPC Managed SLURM
A managed SLURM offering for GPU compute, letting teams
keep sbatch scripts and ditch cluster maintenance, hosting a minimal SLURM environment on top-tier GPUs
, with
queues for H100, B200, and A6000 nodes and fair-share scheduling enabled

4. Lyceum Technology (Lyceum Cloud)
Focused on sovereign/European GPU infrastructure with optimized Slurm+MIG configurations, positioning itself as
offering the efficiency of a modern AI platform with the security of a sovereign cloud

For evaluation, NorthWind and Crusoe are the most mature "as-a-service" plays (both built on the open-source Slinky operator bridging Slurm and Kubernetes), while BUZZ HPC and Lyceum target smaller teams or sovereign-cloud use cases.
