This repo contains several OmniReduce experiments, including micro-benchmark, CV/NLP/Recommandation models implemented in PyTorch. You can use them to reproduce the evaluation results in our SIGCOMM'21 paper.
Before running experiments, you should install PyTorch with OmniReduce according to this. All the scripts including benchmark and model training are based on the PyTorch distributed package, so you can get the NCCL results for performance comparison by changing the --backend flag to nccl for performance comparison.
SIGCOMM 2021 Artifact Evaluation Getting Start Guide for OmniReduce is in the folder docs.
