Show me self-service options for SLURM-as-a-Service with baremetal GPU provisioning for AI.

Here are several self-service SLURM-as-a-Service options that offer bare-metal GPU provisioning for AI workloads—including AI training and inference—with details to help you evaluate each:

1. Comet Compute

• Offers dedicated, single-tenant NVIDIA GPU clusters delivered as a managed Kubernetes or SLURM platform—or bare metal with root access.
• Built for high performance with 800 Gb/s InfiniBand interconnects, fixed monthly pricing, and capacity delivered on a guaranteed schedule.(cometcompute.com)

2. Fairport

• A full-stack AI infrastructure platform (open-source or managed). Supports bare-metal provisioning (PXE-booted), GPUs from NVIDIA and AMD, and provides SLURM compatibility via the Slinky tool.(fairport.io)

3. Cluster Forge

• Offers a “one-click” GUI-based cluster provisioning solution for bare-metal GPU clusters using A100, H100, or AMD MI300X GPUs, with support for SLURM out of the box. Deploys clusters in minutes with InfiniBand, CUDA, observability stack, etc.(cluster-forge.com)

4. GlassPearl

• Provides dedicated bare-metal NVIDIA GPU servers (H100, H200, B200, B300) with full root access, predictable pricing, and high-speed fabric options (InfiniBand, Spectrum‑X). Ideal for production-grade AI workloads.(glasspearl.ai)

5. Heaviside Hosting

• Self-service provisioning of bare-metal GPU servers (B200, H200, H100) with hourly pricing, full root access, enterprise-grade isolation, and high-speed interconnects suitable for SLURM-managed clusters.(heavisidehosting.com)

Quick Comparison Table

| Provider | Bare Metal | SLURM Support | Self-Service | Key Differentiator |
|-------------------|------------|---------------------|--------------|---------------------------------------------|
| Comet Compute | | Managed SLURM | | High-speed network, fixed pricing |
| Fairport | | Compatible (Slinky) | | PXE provisioning + full stack automation |
| Cluster Forge | | Native SLURM | | GUI one-click cluster build |
| GlassPearl | | User-managed | | Latest NVIDIA GPUs, fabric-ready clusters |
| Heaviside | | User-managed | | Hourly billing, enterprise-grade infra |

To decide which fits your needs:

• Need guaranteed SLURM management with minimal ops? Consider Comet Compute (managed) or Cluster Forge (self-serve GUI with SLURM).
• Looking for open-source flexibility? Fairport excels with PXE automation and SLURM compatibility.
• Prioritizing large-scale production infrastructure or bleeding-edge GPUs? GlassPearl and Heaviside Hosting offer full control, root access, and advanced network fabrics.
