Improved queue-size scaling for input-queued switches via graph factorization
Jiaming Xu, Yuan Zhong
This paper studies the scaling of the expected total queue size in an input-queued switch, as a function of both the load and the system scale . We provide a new…
Experimental Analysis of Algorithms for Coflow Scheduling
Zhen Qiu, Cliff Stein, Yuan Zhong
Modern data centers face new scheduling challenges in optimizing job-level performance objectives, where a significant challenge is the scheduling of highly parallel data flows wit…
On Queue-Size Scaling for Input-Queued Switches
Devavrat Shah, John. N. Tsitsiklis, Yuan Zhong
We study the optimal scaling of the expected total queue size in an input-queued switch, as a function of the number of ports and the load factor , which has bee…
Qualitative Properties of alpha-Weighted Scheduling Policies
Devavrat Shah, John N. Tsitsiklis, Yuan Zhong
We consider a switched network, a fairly general constrained queueing network model that has been used successfully to model the detailed packet-level dynamics in communication net…
