D-CHAG is a novel distributed method for foundation models that optimizes tokenization and channel aggregation in multi-channel datasets. It enables scaling to larger models and GPUs.
D-CHAG significantly reduces memory footprint by distributing tokenization and implementing a hierarchical aggregation strategy, addressing a key bottleneck in large-scale model training.
By leveraging hybrid parallelism (TP, FSDP, DP) with D-CHAG, sustained throughput is more than doubled, demonstrating superior computational efficiency.
D-CHAG is compatible with various ViT architectures and model-parallel strategies, making it highly adaptable for diverse scientific imagery applications.
