With the rapid growth of cloud computing, frequent workload bursts show an increasing influence on the quality of service and energy efficiency of cloud-based data centers. Existing virtual machine placement schemes are expected to optimize either quality of service or energy efficiency for cloud data centers running under bursty workload conditions. To bridge this gap, new research by TSYS School computer scientist Yi Zhou and his colleagues at Jinan University, Hainan University, University of Exeter and Auburn University proposes a burst-aware and thermal-efficient virtual machine placement technique that leverages a split-and-recombine algorithm to deal with bursty workloads. Their technique prioritizes critical workloads while preventing low-priority workloads from starvation, thereby assuring quality of service. It does so by utilizing an enhanced simulated annealing algorithm to offer optimal thermal-efficient virtual machine placement solutions, aiming to minimize the energy consumption of data centers. To facilitate estimating energy consumption, a thermal model that takes into account heat re-circulation effects is integrated into their technique. Experiments discussed in the study, which is set to appear in a future issue of IEEE Transactions on Services Computing, indicate that the proposed new technique reduces workload delay by 18%, while also lowering total energy consumption by anywhere between 27.8% and 49.4%.
Seven Turner College Management and Marketing Faculty Have Combined to Produce Eight A-Level Journal Publications Between 2021 and the Present
A number of faculty in the Turner College's Department of Management and Marketing, which includes faculty in management information systems, have produced A-level journal publications in the last few years. This report covers that activity, starting with John Finley , the chairperson of the department. Professor Finley published a paper in the Journal of Computer Information Systems in 2022. Finley is joined by Kirk Heriot , the Crowley Distinguished Chair in Entrepreneurship. Heriot, who earned a PhD in management from Clemson University, published in a 2021 issue of Small Business Economics . One of the study's co-authors, Andres Jauregui of Fresno State University, was previously a member of the Turner College's economics faculty. Next is Johnny Ho , a professor of management, who has a 2022 publication in the Journal of Computer Information Systems . Ho has won CSU's Excellence in Research Award on multiple occasions, while he has compiled 2...
