Popcorns-Pro: A Cooperative Network-Server Approach for Data Center Energy Optimization
Sai Santosh Dayapule, Kathy Nguyen, Gregory Kahl +2
Data centers have become a popular computing platform for various applications, and they account for nearly 2% of total US energy consumption. Therefore, it has become important to…
Overage and Staleness Metrics for Status Update Systems
Peng Zou, Jin Zhang, Xianglin Wei +1
Status update systems consist of sensors that take measurements of a physical parameter and transmit them to a remote receiver. Age of Information (AoI) has been studied extensivel…
On Age and Value of Information in Status Update Systems
Peng Zou, Omur Ozel, Suresh Subramaniam
Motivated by the inherent value of packets arising in many cyber-physical applications (e.g., due to precision of the information content or an alarm message), we consider status u…
Maintaining Information Freshness in Power-Efficient Status Update Systems
Parisa Rafiee, Peng Zou, Omur Ozel +1
This paper is motivated by emerging edge computing systems which consist of sensor nodes that acquire and process information and then transmit status updates to an edge receiver f…
Optimizing Information Freshness Through Computation-Transmission Tradeoff and Queue Management in Edge Computing
Peng Zou, Omur Ozel, Suresh Subramaniam
Edge computing applications typically require generated data to be preprocessed at the source and then transmitted to an edge server. In such cases, transmission time and preproces…
HolDCSim: A Holistic Simulator for Data Centers
Fan Yao, Kathy Ngyugen, Sai Santosh Dayapule +4
Cloud computing based systems, that span data centers, are commonly deployed to offer high performance for user service requests. As data centers continue to expand, computer archi…
Trading Off Computation with Transmission in Status Update Systems
Peng Zou, Omur Ozel, Suresh Subramaniam
This paper is motivated by emerging edge computing applications in which generated data are pre-processed at the source and then transmitted to an edge server. In such a scenario,…
A Hierarchical WDM-based Scalable Data Center Network Architecture
Maotong Xu, Jelena Diakonikolas, Eytan Modiano +1
Massive data centers are at the heart of the Internet. The rapid growth of Internet traffic and the abundance of rich data-driven applications have raised the need for enormous net…
A Reconfigurable High-Performance Optical Data Center Architecture
Chong Liu, Maotong Xu, Suresh Subramaniam
Optical data center network architectures are becoming attractive because of their low energy consumption, large bandwidth, and low cabling complexity. In\cite{Xu1605:PODCA}, an AW…
Relative Age of Information: A New Metric for Status Update Systems
Peng Zou, Omur Ozel, Suresh Subramaniam
In this paper, we introduce a new data freshness metric, relative Age of Information (rAoI), and examine it in a single server system with various packet management schemes. The (c…
Waiting before Serving: A Companion to Packet Management in Status Update Systems
Peng Zou, Omur Ozel, Suresh Subramaniam
In this paper, we explore the potential of server waiting before packet transmission in improving the Age of Information (AoI) in status update systems. We consider a non-preemptiv…
Chronos: A Unifying Optimization Framework for Speculative Execution of Deadline-critical MapReduce Jobs
Maotong Xu, Sultan Alamro, Tian Lan +1
Meeting desired application deadlines in cloud processing systems such as MapReduce is crucial as the nature of cloud applications is becoming increasingly mission-critical and dea…
On the Approximability of Related Machine Scheduling under Arbitrary Precedence
Vaneet Aggarwal, Tian Lan, Suresh Subramaniam +1
Distributed computing systems often need to consider the scheduling problem involving a collection of highly dependent data-processing tasks that must work in concert to achieve mi…
Impact of Wavelength and Modulation Conversion on Transluscent Elastic Optical Networks Using MILP
Xu Wang, Maite Brandt-Pearce, Suresh Subramaniam
Compared to legacy wavelength division multiplexing networks, elastic optical networks (EON) have added flexibility to network deployment and management. EONs can include previousl…
