Sign off on proof,
not green lights.
An independent team on your side before vendor milestones are paid. We burn in every node, soak test thermals, validate the fabric and optics, and run collective bandwidth tests across the whole cluster, then hand you the evidence.

What you get.
Acceptance criteria
Pass and fail thresholds agreed with you and written into the vendor milestones before delivery.
Burn-in and thermal soak
Sustained load across every GPU to catch weak parts, throttling, and cooling problems early.
Fabric and optics validation
Link errors, optic health, cabling, and routing checked across the fabric, so flapping links are found now.
Collective benchmarks
NCCL or RCCL all-reduce and all-to-all tests at cluster scale, compared against expected line rate.
Remediation tracking
Failures logged, assigned to the vendor, retested, and closed before you sign.
Scope and deliverables.

Where this fits.
Teams that want evidence before releasing large vendor payments.
First deployments where the hardware, fabric, and facility are all new together.
Added capacity that must perform like the cluster it joins.
How the work runs.
Phased, with a written deliverable at every gate. Stop after any phase, or keep us on retainer.
- Criteria: thresholds agreed and written into milestones.
- Preparation: test plan, tooling, and schedule with the vendor and facility.
- Testing: burn-in, soak, fabric, storage, and collective benchmarks.
- Remediation: failures tracked with the vendor through retest.
- Sign-off: written report, then handover to your team or Crystal Cloud operations.
