What Is Burn-In Testing?_
Burn-in testing runs GPU hardware at sustained high load for an extended period (typically 24–72 hours) after initial deployment to identify early failures (infant mortality). Burn-in stresses power delivery, cooling, memory, and interconnects simultaneously. Components that survive burn-in are statistically far less likely to fail in production.
Technical Details
Burn-in testing exploits the bathtub curve of component failure rates: most hardware failures occur either very early (infant mortality) or very late (wear-out) in a component's life. By running hardware at sustained high stress immediately after deployment, burn-in forces infant mortality failures to manifest before the system enters production. GPU burn-in typically involves running compute-intensive workloads (GEMM benchmarks, stress tests) at maximum GPU utilization for 24–72 hours while monitoring GPU temperatures and thermal throttling, memory error rates (correctable and uncorrectable ECC errors), power consumption stability, network link error counters, and cooling system performance (flow rates, delta-T). Any anomaly during burn-in triggers investigation and remediation before handoff.
How Leviathan Systems Works with Burn-In Testing
Leviathan offers hardware burn-in under an agreed customer/OEM-approved procedure for the exact equipment. The engagement defines duration, available power and cooling, qualified personnel, authorized tools, recorded conditions and results, exception handling, retest and acceptance. This is distinct from a power-on check or full cluster commissioning and does not guarantee production reliability.
