  "Description": "Detects central processing unit topology,\nprocess-available cores, host and container memory, graphics\nprocessing unit hardware, and reports the apparent availability\nof 'CUDA', 'Metal', 'ROCm', and 'OpenCL' compute backends, with\na read-only shared-library inventory for the 'CUDA' runtime,\n'cuBLAS', 'cuFFT', 'cuSOLVER', 'cuRAND', and optional 'NCCL'\nlibraries. Detection uses operating-system information,\ndocumented platform interfaces, and optional command-line\nutilities, without requiring a GPU framework, 'Python', or a\nvendor software development kit. Backend interpretation follows\nthe official 'CUDA'\n<https://docs.nvidia.com/cuda/cuda-driver-api/>, 'Metal'\n<https://developer.apple.com/documentation/metal>, 'ROCm'\n<https://rocm.docs.amd.com/>, and 'OpenCL'\n<https://registry.khronos.org/OpenCL/> documentation. 'NCCL'\nversion inspection follows its documented API\n<https://docs.nvidia.com/deeplearning/nccl/user-guide/docs/api/comms.html>.\nProcess-level GPU memory samples, multi-device inventories, and\nversioned hardware manifests support reproducible benchmarks.\nMissing hardware, drivers, libraries, and utilities are handled\nsafely.",
