How to Identify Intel and AMD CPU Models in HPC Systems

Accurately identifying CPU models in HPC systems is essential for maintenance, compatibility checks, and performance optimization. Here's a straightforward guide:

Step 1: Using Linux Commands

• Open a terminal on your HPC node.
• Run the following command to quickly identify CPU model:
• lscpu | grep 'Model name'

This command clearly indicates the CPU model and architecture.

Step 2: Using /proc/cpuinfo

• View detailed CPU information with:
• cat /proc/cpuinfo | grep 'model name' | uniq
• This provides explicit CPU model details for Intel and AMD processors.

Step 3: Using dmidecode (Hardware Detection)

• Obtain more detailed hardware information:
• sudo dmidecode -t processor
• This command lists comprehensive details including manufacturer, model number, frequency, and core count.

Step 4: Remote Identification via IPMI

• If local access isn't available, remotely connect via IPMI and run similar commands to gather CPU information.

Step 5: Documenting and Verifying

• Record CPU details clearly for future reference and troubleshooting.
• Verify against vendor specifications to confirm exact CPU features and capabilities.

By following these steps, you can reliably identify and document CPU models within your HPC environment, enabling effective maintenance and support.
