WaveAlign: Cache-Aware Query-Row Scheduling for Sparse Attention in Long-Video Generation

Long-video generation with diffusion transformers (DiTs) produces extremely long token sequences, making attention a dominant inference bottleneck. Dynamic sparse attention reduces computation, but its realized speedup remains limited because irregular query-row execution degrades L2 cache locality and increases HBM tr...

DeaMoE: Efficient MoE Structure for Fast Small-Batch Decoding

DeaMoE is proposed, a decoding-efficient MoE architecture, in which the experts are grouped into several departments, and the experts belonging to the same department share most parameters since they come from the same professional field, and additionally each expert contains a few private parameters to reflect its uni...
