X-Stage: An Overlooked Pipeline Stage for Communication-Computation Overlap in DiT Inference
A lightweight Burst-Gap model parameterized by backpressure-free issue time, effective drain rate, and outstanding capacity predicts issue overhead, recovery between bursts, and the onset of backpressure, and two communication-computation fused kernels are redesigned.
