FedZero

Official repository for the paper "FedZero: Leveraging Renewable Excess Energy in Federated Learning." presented at e-Energy'2024. FedZero is an FL system that operates exclusively on renewable excess energy and spare capacity of compute infrastructure to effectively reduce a training’s operational carbon emissions to zero.

The implementation uses:

• Flower and PyTorch for implementing federated learning
• Vessim for simulating the client's energy systems
• Gurobi for solving optimization problems

Installation

To run FedZero you need a Gurobi license. You can get a free academic license here.

Then run:

python -m venv venv
. venv/bin/activate
pip install --upgrade pip
pip install -r requirements.txt

Datasets

• Download of CIFAR and TinyImagenets should work automatically through torchvision.

• For the shakespeare experiments, run the following in the base directory:

  git clone git@github.com:TalwalkarLab/leaf.git
  cd leaf/data/shakespeare
  ./preprocess.sh -s niid --sf 1.0 -k 0 -t sample -tf 0.8
  

• For the Google speech dataset, run the following in the base directory:

  cd data/speech
  mkdir data
  sh download_gspeech_v2.sh data
  python make_data_list.py -v data/validation_list.txt -t data/testing_list.txt -d data -o data
