Coflow completion time
WebJun 23, 2024 · By continuously sampling and training, agent learns the appropriate MLFQ threshold setting policy, which reduces the average coflow completion time. M-DRL regards the coflow scheduling process with one hour as an episode. When an episode ends, the initial state is reset. WebMar 23, 2024 · To improve the execution performance of such a job, it is crucial to reduce the completion time of a coflow, as it can contribute more than 50 percent of the job completion time. While several coflow schedulers have been proposed, we observe that routing, as a factor greatly impacting the Coflow Completion Time (CCT), has not been …

WebJul 5, 2016 · A coflow is a collection of related parallel flows that occur typically between two stages of a multi-stage compute task in a network, such as shuffle flows in MapReduce. The coflow abstraction allows applications to convey their semantics to the network so that application-level requirements (e.g., minimizing the completion time of the slowest flow) … Webtion mechanism achieves average coflow completion time within 4×of the optimal as long as (co)flows are prioritized with respect to the ordering. Sincronia uses a …

WebJun 1, 2015 · Existing coflow scheduling methods [2,17, 18, 22,25] aim to optimize the coflow completion time (CCT) or coflow-level delay. However, these methods are suboptimal in minimizing the JCT of a data ...
WebFeb 19, 2024 · We then propose a 2-approximation algorithm, called Reco-Sin, for single coflow scheduling to minimize the coflow completion time (CCT). For multiple coflows, we derive Reco-Mul to minimize the total weighted CCT, which can transform any non-preemptive multi-coflow scheduling in packet switches to a scheduling scheme in OCS. history of oakwood universityWebNov 28, 2024 · State-of-the-art CoFlow schedulers in essence approximate the classic online Shortest-Job-First (SJF) scheduling, designed for a single CPU, in a distributed setting, with no coordination among how the flows of a CoFlow at individual ports are scheduled, and as a result suffer two performance drawbacks: (1) The flows of a CoFlow … history of oberoi hotelWebJun 1, 2024 · Coflow is defined as the parrellel flows between two successive computation stages of data-parallel jobs.
