CPUFreqRizer

Balancing Power Efficiency and Performance with CPU Scaling Configuration

Overview

CPUFreqRizer is a Python package that determines the optimal CPU scaling configuration for your system based on your workload. It takes user input, such as task type, expected load, and performance requirements, and generates a structured response with recommended CPU scaling policies.

Installation

pip install cpufreqizer

Overview of Functionality

CPUFreqRizer uses an LLM (Large Language Model) to generate a structured response with CPU scaling recommendations. The user provides details about their workload, and the package returns a list of recommended CPU scaling policies, including the appropriate governor and kernel parameters.

Using the Package

from cpufreqizer import cpufreqizer

response = cpufreqizer(user_input={"task_type": "cpu-intensive", "expected_load": 0.8, "performance_requirements": "high"})

Default Behavior

By default, CPUFreqRizer uses the llm7 LLM from the langchain_llm7 package. This is a free-tier LLM with sufficient rate limits for most use cases. You can safely pass your own llm instance (based on these docs) if you want to use a different LLM. For example, to use the openai LLM:

from langchain_openai import ChatOpenAI
from cpufreqizer import cpufreqizer

llm = ChatOpenAI()
response = cpufreqizer(user_input={"task_type": "cpu-intensive", "expected_load": 0.8, "performance_requirements": "high"}, llm=llm)

Obtaining a Free API Key

To use a different LLM with a higher rate limit, you can obtain a free API key on the llm7.io website. You can then pass this API key via environment variable LLM7_API_KEY or directly to the cpufreqizer function:

cpufreqizer(user_input={"task_type": "cpu-intensive", "expected_load": 0.8, "performance_requirements": "high"}, api_key="your_api_key")
