veScale-FSDP: Flexible and High-Performance FSDP at Scale
Researchers introduce veScale-FSDP, a redesigned Fully Sharded Data Parallel system that overcomes limitations of current FSDP implementations used for training large-scale AI models. The new system features flexible RaggedShard format and structure-aware planning, achieving 5-66% higher throughput and 16-30% lower memory usage while supporting advanced training methods and scaling to tens of thousands of GPUs.
