New Study by Zhou Presents Technique to Reduce Energy Consumption of Cloud Data Centers

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%.

Four Turner College Faculty Recognized for Outstanding Teaching

CSU Head Women's Soccer Coach Jay Entlich recently released a list of CSU faculty who have been chosen by a player as a member of the CSU faculty who has impacted the player in a positive way along their journey at CSU. Four Turner College faculty were included on the list, along with the player who nominated each. Management professor Phil Bryant was named by Sophia Leal , a freshman midfielder from Oxford, Georgia. Sophia attended Eastside High School and was a two-time all-region selection during her high school career. Through the first 10 games of 2024, she has scored one goal and recorded three assists. Next, management professor John Finley was named by Lizz Forshaw , a graduate student forward from Stockton, England. Lizz, who attended IMG Academy in south Florida, has scored four goals and recorded four assists this season. During her senior year in 2023, she scored three goals and recorded two assists. As a junior in 2022, Lizz scored three goals ...

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...

TSYS School, Jianhua Yang, Lixin Wang Each among Top Five in the World

New research by computer scientists in the School of Information Technology at Universiti Utara Malaysia that ranks institutions and individuals on the basis of scholarship in the area of stepping-stone attacks heaps praise on the Turner College’s TSYS School of Computer Science and two of its faculty – Jianhua Yang and Lixin Wang . The article, published in the April 2023 issue of the International Journal of Research in Engineering and Science , provides a bibliometric analysis of both publication and citation data from 2000 to September of 2022 related to research on stepping-stone intrusion. Among several results, it reports that Columbus State University ranks second worldwide, trailing only the University of Houston, using total publications on the subject as the basis of comparison. A number of other U.S. institutions appear in the top 10, including third-ranked North Carolina State University, fourth-ranked University of Illinois, sixth-ranked Iowa State U...
