Our production experience in large-scale data-processing pipelines shows that, despite its attractive programming model, memory-mapped I/O (_mmap-IO_) on distributed file systems (DFS) exhibits severe operational pathologies—livelocks during write-heavy phases, chronically low multi-threaded thro...

Autoregressive decoding inherently limits the inference throughput of Large Language Model (LLM) due to its sequential dependency. Speculative decoding mitigates this by verifying multiple predicted tokens in parallel, but its efficiency remains constrained by what we identify as verification het...

Chain-of-Thought reasoning significantly improves the performance of large language models on complex tasks, but incurs high inference latency due to long generation traces. Step-level speculative reasoning aims to mitigate this cost, yet existing approaches face a long-standing trade-off among a...
