    Certified Parallel-in-Time Sinkhorn for Dynamic Entropic Optimal Transport

    Xinyang Wen

    cs.DC · cs.LG

    Dynamic applications, including optimal-transport Flow Matching, repeatedly solve related entropic optimal transport problems, yet conventional distributed Sinkhorn processes frames sequentially and synchronizes after every iteration. We present TemporalSinkhorn, a parallel-in-time executor that batches future candidates and their repairs without making output accuracy speculative. A centered, row-sharded certificate accepts only a...

    Consensus In Asynchrony: Strictly Formal

    Ivan Klianev

    cs.DC

    In this paper, we resolve the apparent contradiction between the proven possibility of deterministic crash-tolerant consensus in a fully asynchronous environment and the reconfirmation of the FLP impossibility result by Attiya, Castañeda, and Rajsbaum. With the use of a strictly formal framework that extends their reasoning, we close this fundamental gap in theory. Specifically, we demonstrate that a single protocol phase separates their...

    SpecBox: Speculative Sandbox Scheduling for Efficient LLM Agent Serving

    Yihui Zhang, Tianyu Wo, Jinghao Wang, Xiaoyang Sun, Menghao Zhang, Cangzhou Yuan, Li Li, Chunming Hu, Albert Y....

    cs.DC · cs.AI · cs.LG · cs.PF

    As LLM agents increasingly rely on the Model Context Protocol (MCP) to invoke isolated external sandboxes, disaggregated sandbox deployment introduces a fundamental tension between resource utilization and interactive tail latency. Persistent long-lived sandbox reservations incur excessive memory overhead at scale, while lazy on-demand instantiation generates severe cold-start penalties that degrade response performance under multi-tenant,...
