Hardware reports
What the host reports
The host daemon detects the card when it is set up (nvidia-smi on NVIDIA, rocm-smi on AMD, the system profile on Apple silicon) and, on NVIDIA hosts, reads the driver again every minute. It writes a report: the GPU name, its memory, how many cards, the driver version, the CPU, and the host fingerprint. It signs the report with the island's probe key, the same key the hourly probes check. The site verifies the signature, checks that the report names the island, and for house islands that its host fingerprint matches the one the probes recorded onchain. Only a verified report changes how the island is drawn.
curl https://gpuislands.com/api/state | jq '.islands[] | {name, gpu: .hw.report.gpu, verified: .hw.verified}'A report says what the host's driver sees. It does not prove that every call ran on that card; the probes prove the island answers, the receipts prove what was paid. An island whose report is missing or does not verify is shown as "hardware not reported".
The house islands
| Island | Hardware | Notes |
|---|---|---|
Coral | 1x GeForce GTX 1080 Ti, 11 GB | GPU queue (embeddings); shares the card with Reef |
Reef | 1x GeForce GTX 1080 Ti, 11 GB | Qwen3 4B; shares the card with Coral |
Lagoon | No GPU | Files served from disk on the same host |
The house islands run on one server with one GTX 1080 Ti, and the map draws them that way: two small, weathered GeForce islands and a shed.
Island designs by GPU family
The Raise panel shows a labelled preview of each design. Previews are never placed in the sky; an island takes its shape only from a verified report.
