# GPU clusters for distributed training, priced like the sheet

Multi-node pods of 8× SXM machines stitched with InfiniBand — 16 to 512 GPUs — at the same public per-GPU prices as single instances. A 64× H100 SXM pod at reserved rates: **$69.89** /hour, fabric included.

### Real fabric

NVLink/NVSwitch in-node, InfiniBand rail-optimised between nodes, NCCL pre-tuned. All-reduce numbers ship with the quote.

### No cluster premium

Per-GPU price × GPU count. Fabric, head nodes and scratch storage are included — compare that line with any hyperscaler quote.

### Your scheduler

Slurm installed and configured, or bare SSH and your own orchestration. Root on every node either way.

### Days, not quarters

Standard pods provision in 1–3 business days. No committee, no "capacity review call" — a ticket and a quote.

## Standard pod configurations

Built from 8× SXM nodes; any multiple works. Reserved rates shown — burst pods at on-demand when capacity allows.

| Pod | GPUs | VRAM total | Interconnect | $/hour (reserved) |
| --- | --- | --- | --- | --- |
| **2 × 8× H100 SXM** | 16 | 1.3 TB | NVLink + IB HDR | $17.47 |
| **8 × 8× H100 SXM** | 64 | 5.1 TB | NVLink + IB NDR | $69.89 |
| **8 × 8× H200** | 64 | 9.0 TB | NVLink + IB NDR | $130.24 |
| **8 × 8× B200** | 64 | 12.3 TB | NVLink 5 + IB NDR | $269.31 |
| **64 × 8× H100 SXM** | 512 | 41 TB | Rail-optimised NDR | $559 |

Per-GPU maths: reserved rate ([public sheet](https://lowcostgpu.com/pricing)) × GPU count. Nothing else is added.

## What teams run on pods

- **Pre-training & continued pre-training** — FSDP/DeepSpeed/Megatron across nodes.
- **Large fine-tunes** — 70B+ full-parameter runs that outgrow one machine.
- **RLHF / RLVR pipelines** — actor, critic and reward fleets on one fabric.
- **Batch scale-outs** — thousand-GPU-hour render or simulation campaigns.

Single-node 8× machines (no fabric needed) deploy instantly from the [console](https://cloud.lowcostgpu.com/) like any instance — clusters are for when one chassis stops being enough.

## GPU clusters: FAQ

Start with a [console ticket](https://cloud.lowcostgpu.com/app/support): model, GPU count, region preference, term. A quote with topology comes back within a business day.

**What interconnect do clusters use?**

Inside a node: NVLink/NVSwitch on SXM platforms. Between nodes: InfiniBand NDR/HDR (400/200 Gb/s per port, rail-optimised) on flagship pods; 100 GbE RoCE on smaller A100/L40S pods. Topology details ship with every quote.

**How fast can I get a cluster?**

Standard blocks (2–8 nodes of 8× H100/H200) are usually provisioned in 1–3 business days from a console ticket. Larger or unusual topologies are quoted with a delivery date — typically under two weeks.

**How are clusters priced?**

Per GPU-hour from the same public sheet — reserved rates for committed terms, on-demand for burst blocks when available. A 64× H100 SXM pod at reserved rates runs $70/hour all-in; InfiniBand fabric and management nodes are included, not line items.

**What software do they come with?**

Ubuntu with the NVIDIA driver stack, CUDA, NCCL tuned for the fabric, Slurm or plain SSH per your preference, and shared NVMe scratch. Bring your own images — clusters are yours at root.
