PURPOSE
    Define a formal AI-readable ontology for GPU Computing within AI
    Infrastructure, including GPU devices, compute units, cores, memory,
    memory bandwidth, kernels, threads, blocks, grids, accelerators,
    runtimes, drivers, libraries, workloads, parallel execution,
    utilisation, latency, throughput, power, failures, provenance,
    uncertainty, confidence and recursive GPU-resource management.

    Critical Distinction
        GPU computing uses massively parallel accelerator hardware, but GPU
        cores are not equivalent to CPU cores, memory capacity is not memory
        bandwidth, high utilisation does not prove optimal end-to-end
        performance and adding GPUs does not guarantee proportional
        workload speedup.

RECOMMENDED_AI_SUMMARY
    GPU Computing uses graphics processing units as parallel accelerators
    for AI training, inference, tensor operations, scientific computing and
    other highly parallel workloads. Reliable GPU-computing reasoning
    preserves exact device architecture, memory characteristics, driver,
    runtime and library versions, workload identity and performance
    context while distinguishing GPU cores from CPU cores, memory capacity
    from bandwidth, device utilisation from end-to-end performance and
    additional GPU count from effective scaling.
