Accelerating Sharded Data Parallelism at Scale with Federated Learning
TL;DR
Two hybrid algorithms, FL+FSDP and FL+HSDP, enhance sharded data parallelism by integrating federated learning principles, achieving up to 8.04 times faster data processing and improved model quality.
✦ Why It Matters
Consider implementing FL+FSDP or FL+HSDP in your next large-scale AI training project to boost efficiency.
Key Takeaways
- Explore FL+FSDP and FL+HSDP for large-scale AI training.
- Reduce communication overhead in distributed GPU setups.
- Manage global batch sizes effectively with federated learning principles.
- Achieve faster data processing and improved model quality.
How It Works
FL+FSDP and FL+HSDP interleave sharded data parallelism with federated learning techniques, allowing large models to be trained in smaller, decentralized groups. This structure reduces the need for extensive communication between groups, which is a common bottleneck in traditional DP methods.
By aggregating results locally within these groups before a global update, the algorithms maintain efficiency while ensuring that the overall training process remains effective.
