Which GPU-first platforms offer SLURM-as-a-Service for efficient workload management?

Several GPU-first neoclouds now offer SLURM-as-a-Service (usually via a "Slurm-on-Kubernetes" architecture) so teams get familiar HPC job scheduling without managing the control plane themselves:

1. CoreWeave – SUNK (Slurm on Kubernetes)

SUNK ("Slurm on Kubernetes") integrates Slurm, a popular workload manager for HPC and AI, with Kubernetes, eliminating the need to maintain separate infrastructure for Slurm and Kubernetes workloads for greater efficiency and better resource utilization.

It supports a high volume of isolated, customizable user environments and enables both inference and training within a single cluster.
Analysts note
CoreWeave commands a higher price for managed slurm clusters (roughly 10-15% per GPU-hr) vs competitors like Nebius, Fluidstack, Crusoe, Lambda, and Together.ai.

2. Nebius – Managed Soperator

Nebius offers Managed Soperator, a fully managed Slurm-on-Kubernetes solution, with configuration recently overhauled to offer more options and granularity for self-service users.

3. Lambda – Managed/Unmanaged Slurm

Both Unmanaged and Managed Slurm run on Lambda's 1-Click Clusters with NVIDIA HGX B200 and H100 GPUs, with Slurm job management optimized for AI workloads.

Lambda handles the complexities of Slurm administration, with Managed Slurm providing comprehensive support and management.

4. Crusoe – Crusoe Managed Slurm

Crusoe runs Managed Slurm on its Crusoe Managed Kubernetes substrate, giving customers topology-aware visibility and GPU telemetry, using Slinky, SchedMD's official project for running Slurm on Kubernetes.

5. AMD Spur-Cloud (emerging alternative)

Spur-Cloud extends AMD's Spur scheduler into a complete GPU-as-a-Service solution, layering on a web UI, billing, and multi-tenancy behind a Slurm-compatible CLI/API.

Also offering managed Slurm: Fluidstack, Voltage Park (via Penguin Solutions), and Together.ai, per the same competitive comparison above.
