Check Current Power Limits: - Use the command `nvidia-smi -q -d POWER` to see the current power limit settings. - This will show you the current power limit, maximum power limit, and other power-related information. #### 2. Set a New Power Limit: - Use the command `sudo nvidia-smi -i -pl ` to set a new power limit. - Replace `` with the ID of the GPU you want to modify (e.g., 0 for the first GPU). - Replace `` with the desired power limit in watts (e.g., 250 for 250W). - Example: `sudo nvidia-smi -i 0 -pl 250` Persistence: To make the power limit persistent across reboots, you'll need to create a custom `systemd `service or script that runs this command on startup. #### 3. Verify the Settings: - After setting the power limit, use the command `nvidia-smi -q -d POWER` again to verify that the new power limit has been applied. - Check the output to ensure that the "Current Power Limit" reflects the value you set. #### 4. Persist the Power Limit on Boot Create a `systemd `service: ``` sudo nano /etc/systemd/system/nvidia-power-limit.service ``` Paste this: ``` [Unit] Description=Set NVIDIA GPU Power Limit After=multi-user.target [Service] Type=oneshot ExecStart=/usr/bin/nvidia-smi -i 0 -pl 300 RemainAfterExit=yes [Install] WantedBy=multi-user.target ``` Enable it: ``` sudo systemctl enable nvidia-power-limit.service sudo systemctl start nvidia-power-limit.service ``` # Mobile Home Lab ### Resources - [https://github.com/mozanunal/llm-tools-kiwix](https://github.com/mozanunal/llm-tools-kiwix) - Expose offline Kiwix ZIM archives (like Wikipedia, Stack Exchange, DevDocs) to Large Language Models (LLMs) via the LLM CLI tool and Python library.
