Researchers have developed MegaScale-Data, a new distributed data loading architecture designed to improve the efficiency of training large foundation models (LFMs) from multiple data sources. The system addresses challenges like workload imbalance caused by non-uniform data distribution and excessive memory usage from replicated data access states. MegaScale-Data introduces disaggregated preprocessing, a centralized data plane for orchestration, and an auto-partitioning mechanism, resulting in significant improvements in training throughput and reductions in memory consumption.
