Taichi: Elastic Multi-LLM Serving with Coordinated Memory–Compute Multiplexing

The rapid adoption of LLM applications is driving up serving cost, yet GPUs remain underutilized in practice due to single-model provisioning and highly variable, long-tailed workloads. Co-locating two or more LLMs on one GPU can improve utilization, but it requires fast and coordinated control of both KV cache/paramet...

HydraPIM: A Heterogeneous PIM Architecture for Efficient Attention in Long-Context LLMs

The growing demand for long-context LLM inference has exposed a critical bandwidth–capacity trade-off in memory systems, rendering single-tier PIM architectures ineffective. HBM-PIMs offer high bandwidth but limited capacity, while DIMM-PIMs provide scalability at the cost of lower bandwidth; neither satisfies the thro...
