WebMay 1, 2024 · Varys: Varys [8] aims at minimizing the average coflow completion time without considering isolation guarantees. It showed that strictly minimizing the average CCT is an NP-hard problem [8] . So it employs an efficient smallest-effective-bottleneck-first (SEBF) heuristic that always schedules a coflow with the smallest bottleneck’s … WebApr 25, 2014 · EC2 deployments and trace-driven simulations show that communication stages complete up to 3.16X faster on average and up to 2X more coflows meet their deadlines using Varys in comparison to per-flow mechanisms. Moreover, Varys outperforms non-preemptive coflow schedulers by more than 5X. This is a joint work with Yuan …

While schemes like Varys can achieve optimal performance, they require a priori information about coflows which is hard to obtain in practice. Existing non-clairvoyant solutions like Aalo generalize least attained service (LAS) scheduling discipline to address this issue. …
