Researchers have developed novel architectures and techniques to address the escalating latency and energy consumption challenges in serving large language models (LLMs) with long contexts. One approach, AMMA, proposes a memory-centric, multi-chiplet design that replaces GPU compute dies with HBM-PNM cubes to boost memory bandwidth, achieving significant reductions in latency and energy use compared to NVIDIA H100. Another framework, SPIN, unifies sparse attention algorithms with hierarchical KV storage to improve throughput and reduce time-to-first-token by optimizing KV cache management across GPU and CPU memory. Additionally, LayerBoost offers a layer-aware attention reduction method that selectively modifies attention mechanisms within transformer layers, improving efficiency by up to 68% while maintaining model quality.
