Unlocking Microsecond-Scale Latency: A Deep Dive into IMEX for Multi-GPU Inference

Nov 30, 2025 · 5 min read · Introduction In the era of trillion-parameter models, the bottleneck for Large Language Model (LLM) inference is rarely raw compute capability alone. As we scale across multiple GPUs using Tensor Parallelism (TP), the dominant latency factor shifts t...
