[Feature] Distributed Weight Data Parallelism (DWDP) for Sparse MoE Models

Published: Apr 4, 2026

Implementation of Distributed Weight Data Parallelism (DWDP) in SGLang — a parallelism strategy that distributes MoE expert weights across GPUs within a node while keeping attention weights fully replicated. DWDP eliminates synchronization barriers by using asynchronous peer-to-peer prefetches to pull remote expert weights before they are needed, improving performance for MoE models on multi-GPU nodes with NVLink.
