What Is Cluster Validation?_
Cluster validation involves running a suite of tests to verify that all hardware components—GPUs, networking, storage, and cooling—function correctly as an integrated system. It checks for issues like GPU memory errors, network bandwidth bottlenecks, and thermal imbalances. The process typically includes stress tests, latency measurements, and consistency checks against baseline metrics.
Technical Details
Validation often starts with GPU diagnostics (e.g., memory and compute tests) and network fabric tests (e.g., MPI bandwidth benchmarks). For NVLink-based systems, it verifies GPU-to-GPU copper connections within the rack, while separate scale-out networks (InfiniBand or Ethernet) typically use fiber optic cables (e.g., with MPO connectors) and undergo fabric-level throughput and latency tests. The process also includes power and thermal stress runs to ensure the liquid cooling system maintains stable temperatures under full load. All results are compared to the OEM spec for the specific GPU and networking hardware.
How Leviathan Systems Works with Cluster Validation
Leviathan supports agreed rack-and-stack, structured cabling, physical inspection, remediation and handoff documentation. Formal physical-layer tests require confirmed equipment, qualified personnel, method, acceptance criteria and report coverage for the engagement. Full system/software commissioning and cluster performance certification are outside Leviathan’s physical service scope. Leviathan does not perform, coordinate or subcontract liquid-side work.
