WebMay 1, 2024 · According to the optimization objectives, the existing coflow scheduling algorithms can be divided into the following three categories: (1) efficiency-based coflow scheduling, (2) fairness-based coflow scheduling, and (3) scheduling that makes tradeoff between fairness and efficiency. WebThey use a one-shot performance metric—CCT (coflow completion time), which cannot continuously reflect the staleness of the output results for a streaming application.To this end, we propose a new performance metric—coflow age (CA), for coflows generated by distributed streaming applications.
