GPU Clusters
Runcrate Private Cloud deploys bare-metal GPU clusters tailored to your workload. Each cluster is single-tenant — dedicated hardware that only your team can access.Cluster Configurations
| Size | Nodes | GPUs (8 per node) | Best For |
|---|---|---|---|
| Starter | 16 | 128 | Fine-tuning large models, multi-node training |
| Growth | 32–64 | 256–512 | Pre-training mid-size models, large-scale inference |
| Scale | 64–128 | 512–1,024 | Frontier model training, massive parallel workloads |
| Custom | 128+ | 1,024+ | Custom configurations for unique requirements |
What’s Included
Every Private Cloud cluster includes:- Bare-metal servers — No virtualization overhead. Full hardware access with root.
- NVIDIA GPUs — 8 GPUs per node with NVLink for intra-node communication.
- InfiniBand networking — High-bandwidth, low-latency interconnect between nodes for distributed training.
- High-performance storage — NVMe SSDs for fast data access during training.
- Dedicated networking — Private network with no shared bandwidth.
- 24/7 monitoring — Infrastructure health monitoring and alerting.
Cluster Architecture
Use Cases
Distributed Training
Train large language models, vision models, or multimodal models across hundreds of GPUs. InfiniBand ensures efficient gradient synchronization with minimal communication overhead.Production Inference
Serve models at scale with predictable latency. Dedicated hardware means no cold starts and no resource contention.Fine-Tuning at Scale
Run multiple fine-tuning jobs in parallel across your cluster. Full control over scheduling and resource allocation.Research
Experiment with new architectures, training techniques, and scaling laws on dedicated infrastructure without worrying about availability or spot interruptions.Software Stack
You have full control over the software stack. Common setups include:- Kubernetes (managed or self-managed)
- Slurm for HPC-style job scheduling
- Docker / Podman for containerized workloads
- NVIDIA NCCL for multi-GPU communication
- DeepSpeed, Megatron, FSDP for distributed training frameworks
Runcrate can assist with cluster setup and configuration. Managed Kubernetes and Slurm options are available.
