uvx sparkrun setup

One command — installs sparkrun, then launches the guided setup wizard to create a cluster, configure SSH mesh, detect ConnectX-7 NICs, set up sudoers, and enable earlyoom.

Quick Start

# Run an inference workload
sparkrun run qwen3-1.7b-vllm

# Multi-node tensor parallelism (TP maps to node count on DGX Spark)
sparkrun run qwen3-1.7b-vllm --tp 2

# Re-attach to logs, stop a workload, check status
sparkrun logs qwen3-1.7b-vllm
sparkrun stop qwen3-1.7b-vllm
sparkrun status

Ctrl+C detaches from logs — it never kills your inference job. Your model keeps serving.

See the full CLI reference for all commands and options.

Highlights

• Multi-runtime — vLLM, SGLang, llama.cpp out of the box
• Multi-node tensor parallelism — --tp 2 = 2 hosts, automatic InfiniBand/RDMA detection
• VRAM estimation — know if your model fits before you launch (sparkrun show <recipe>)
• Git-based recipe registries — we publish official recipes, community recipes, and benchmarked recipes via Spark Arena, plus you can add your own registries.
• Guided setup wizard — cluster creation, SSH mesh, CX7 auto-detection, sudoers, earlyoom
• Model & container distribution — syncs models and images to cluster nodes over SSH automatically

Spark Arena

Spark Arena is the community hub for DGX Spark recipe benchmarks — browse benchmark results, then run them directly with sparkrun.
