📋 Review: How I Checked the Server

What I did (single SSH command, chained):

1. lscpu — pulls CPU architecture details from /proc/cpuinfo. Tells us cores, threads, model, flags (instruction sets like AVX-512).

2. free -h — reads /proc/meminfo and shows total/used/available memory in human-readable format.

3. nvidia-smi — NVIDIA’s management tool. Reports GPU model, VRAM, driver version, temperature, utilization. Failed because driver isn’t installed.

4. lspci | grep -i gpu — raw PCIe bus scan. Shows what hardware is physically connected, regardless of driver status. This is what caught the RTX 3090.

5. cat /proc/driver/nvidia/version — checks if the kernel module is loaded. Failed — confirming no driver.

What I could’ve done better:

• lshw or dmidecode — more detailed hardware inventory (BIOS, exact memory DIMMs, etc.)
• cuda-smi or glxinfo — alternative GPU checks if CUDA runtime exists without the full driver
• /proc/driver/nvidia/gpus/*/information — another driver-level check
• Stress test — gpu-burn or cuda-samples to actually benchmark the GPU once driver is up
• VRAM size — I inferred 24 GB from the RTX 3090 model name, but didn’t actually verify it empirically (can’t without driver)

What went well:

• Single-shot command — no unnecessary round trips
• lspci saved the day when nvidia-smi failed — good fallback
• Caught the discrepancy: Alibaba calls it “G39” but it’s actually an RTX 3090

Want me to dig deeper with lshw or dmidecode for a more complete picture?
