Ssh Gpu Presence Detection Conditional Lspci Or Nvidia Smi

Detects the presence and count of NVIDIA GPUs on a host by conditionally checking for lspci availability and enumerating VGA devices, falling back to nvidia-smi -q if lspci is unavailable. The command suppresses errors and outputs a numeric count of detected NVIDIA devices, indicating automated GPU capability assessment for workload suitability (e.g., cryptomining or GPU-accelerated computation).
