Ravnest is an open-source distributed deep learning training framework that enables asynchronous parallel training across heterogeneous consumer-grade devices.

Ravnest allows users to train complex deep learning models across a network of diverse consumer PCs, leveraging a novel asynchronous training approach to combine data and model parallelism. It orchestrates distributed training through a four-stage pipeline including matchmaking, zero-bubble asynchronous model parallel training, parallel multi-ring all-reduce for global synchronization, and robust fault recovery. Designed for unreliable hardware and bandwidth constraints, it ensures continuous training even as nodes join or leave.

Key Features

Zero-Bubble Asynchronous Model Parallel Training
Parallel Multi-Ring All-Reduce for Global Synchronization
Fault Recovery & Dynamic Scaling for Continuous Training
Gradient Compression & Adaptive Routing
Support for Heterogeneous Devices (CPU/GPU)
