Large Language Model (LLM) inference is increasingly served on disaggregated clusters that combine different accelerator types, including NVIDIA GPUs, Huawei Ascend NPUs, and Kunlunxin AI processors. We show that these heterogeneous xPUs exhibit distinct energy-performance behaviors across inference phases and model mo...

StreamTrace is presented, a streaming trace analysis system that enables efficient analysis of massive traces on a single computing node with bounded memory consumption and introduces two key techniques: communication pattern-aware chunk partitioning that minimizes cross-chunk dependence and dynamic priority-based chun...

Trace-based performance analysis provides essential insights for understanding and optimizing large-scale parallel applications. However, traces from applications running on tens of thousands of processes can easily exceed terabytes, far surpassing the memory capacity of typical computing nodes. Existing approaches eit...

This work presents a tail-risk-aware turn release scheduling method that jointly decides which ready turn to release next and how much released but unfinished work to maintain, and reduces the P95 of workflow flow time under contention, achieving up to a \(3.50\times\) speedup.

A serving system that treats the diffusion block as a compilation unit that improves end-to-end execution time by up to 2.7 times over the strongest surviving baseline under the same 8-GPU placement and remains feasible at the largest batch sizes where multiple baselines run out of memory, while preserving task quality...

UniEP fuses the MoE communication and computation into MegaKernels, effectively transforming complex architectural tuning into a unified parameter search space for automated adaptability and incorporates a deterministic token ordering mechanism that guarantees numerical consistency with sequential execution, even under...

Prism abstracts the highly dynamic diffusion workload into a predictable, static execution flow transparent to the compiler, and achieves this via three techniques: spatial regularization, temporal stabilization, and specialized kernels that selectively bypass padding data.
