iohann.s.titov@gmail.com Ivan S. Titov CUID (Component Unified Identifier) builds a deterministic 122-bit identifier for a hardware component out of whatever architectural markers it exposes: a PCIe Device Serial Number capability, an SMBIOS or ACPI serial, or a generated fingerprint where none of those exist, combined with unit and revision IDs. The point is that one device gets the same identifier from every tool that asks, which makes correlating GPUs, CPUs and NICs across a fleet tractable without vendor-specific naming. It ships a library and the amdcuid command-line tool. Build and install the example programs ROCm/rocm-systems
