About the Project

In this paper, we present EcoLife, an innovative strategy that leverages multi-generation hardware to co-optimize carbon footprint and service time within the serverless environment. EcoLife extends Particle Swarm Optimization (PSO) to adapt to the variations in serverless computing for making keep-alive and execution decisions. Our experimental results show that EcoLife effectively reduces carbon emissions while maintaining high performance for function execution.

Setup

• Language: Python3.10
• Hardware: This repo is mainly simulation, you don't need any hardware to reproduce the results.
• Libs: Ensure that all the libs are installed.

How to Run:

│eco-life/
  ├──carbon_intensity/
  ├──data/
  ├──motivations/
  ├──node/
  ├──optimizers/
  ├──results/

1. carbon_intensity contains the carbon intensity for various regions, Use one of them to simulate.
2. data contains the profiled data for optimization. (eg. the carbon and energy data for different serverless functions)
3. motivations: 4 motivations in the paper.
4. node: Generate the profiled data. You don't need this.
5. optimizers: different optimizers in Ecolife
6. results: you may need to save your results in this folder.
7. exe_decide.py:Execution Placement Decision Maker.
8. function_mem.csv: Memory consumption of different serverless functions.
9. main.py: You may use it to run the codebase.
10. pso.py: DPSO in Ecolife. You need to change it.
11. utils.py: Help functions.
12. selected_trace.zip: Traces for simulation.

Run:

unzip selected_trace.zip
python3 main.py <add your desired configuration>

When you run the main.py, check the code.

Tasks

Here are some tasks for you.

• Read the paper. link
• Read the code.
• Weakness/improvement of this paper.
• Change DPSO to other heuristic algorithms. If you don't know what's a heuristic algorithm, check this: link(https://optimization.cbe.cornell.edu/index.php?title=Heuristic_algorithms) Note that, you may need to compare the results with DPSO in Ecolife. Plotting a bar figure is a good way to try.
• Don't use 12 days for simulation, it will take 2-3 days. Just use one day.
