About this paper
Sameer Kumar, Norm Jouppi
Researchers at Google Inc. developed fault-tolerant allreduce techniques for data parallel machine learning training, enabling continuous operation on 2-D mesh networks despite localized hardware failures. This approach achieved a maximum end-to-end performance overhead of under 6% on Google TPU-v3 supercomputers, mitigating training disruptions from hardware faults.
Key insights
- Combining non-minimal network routing with strategic data forwarding for partial sums allows for practical fault-tolerant allreduce operations on mesh networks.
- Efficiently adapting established collective communication algorithms can create robust fault-tolerant solutions for distributed ML training without major redesign.
- Maintaining high availability for long-running ML workloads in the face of localized hardware failures is achievable with minimal performance overhead through intelligent communication strategies.
