Evidencepartial
DWDP improves end-to-end output TPS/GPU by 8.8% at comparable TPS/user in the 20-100 TPS/user serving range under 8K input sequence length and 1K output sequence length.
Implicationpartial
Directly stated in abstract with specific numeric improvement percentage and test conditions
Verificationpartial
partial
Evidencepartial
By removing collective inter-rank synchronization, DWDP allows each GPU to progress independently.
Implicationpartial
Directly stated in abstract as a key feature of the method
Verificationpartial
partial
Evidencepartial
existing inference parallelization strategies require layer-wise inter-rank synchronization, making end-to-end performance sensitive to workload imbalance.
Implicationpartial
Directly stated in abstract as motivation for the work
Verificationpartial
partial
Evidencepartial
DWDP (Distributed Weight Data Parallelism), an inference parallelization strategy that preserves data-parallel execution while offloading MoE weights across peer GPUs and fetching missing experts on demand.
Implicationpartial
Directly stated in abstract describing the core method
Verificationpartial
partial
Evidencepartial
We further address the practical overheads of this design with two optimizations for split-weight management and asynchronous remote-weight prefetch.
Implicationpartial
Directly stated in abstract describing implementation details
Verificationpartial

Evidencepartial
Implemented in TensorRT-LLM and evaluated with DeepSeek-R1 on GB200 NVL72
Implicationpartial
Directly stated in abstract with specific implementation and evaluation details
