New POLCA system optimizes LLM serving energy efficiency and latency

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new power control system called POLCA for disaggregated LLM serving, aiming to optimize energy efficiency and latency. Unlike existing methods like NVIDIA's Max-Q, which offer modest gains and can increase latency, POLCA uses a phase-decoupled and model-calibrated approach. This system allows prefill and decode lanes to operate with independent power settings, leading to significant improvements in tokens per joule and reduced end-to-end latency, particularly for Mixture-of-Experts (MoE) models.

    Phase-Decoupled, Model-Calibrated Power Control for Disaggregated LLM Serving

    arXiv:2609.11133v1 Announce Type: new Abstract: Datacenter GPU power is the binding constraint on LLM serving capacity, and production serving has shifted to prefill/decode (PD) disaggregation. Deploying NVIDIA's Max-Q inference profile on a disaggregated B200 system, we found it…
