A Scalable Systems Approach to Big Data Challenges

Hong Jiang, National Science Foundation University of Nebraska – Lincoln

Everyday 2.5 quintillion (2.5×1018, or 2.5 million trillion) bytes of data are created by people. This data comes from everywhere: from traditional scientific computing and on-line transactions, to popular social network and mobile applications. Data produced in the last two years alone amounts to 90% of the data in the world today! This phenomenal growth and ubiquity of data has ushered in an era of “Big Data”, which brings with it new challenges as well as opportunities. In this talk, I will first discuss big data challenges facing computer and storage systems research, brought on by the huge volume, high velocity and great variety (i.e., the 3 Vs) with which digital data are being produced in the world. I will then present research being conducted in my research group that seeks a scalable systems and application-focused approach to addressing some of the challenges, from the many core and storage architectures to the systems and up to the applications.

Dr. Hong Jiang received the B.Sc. degree and the M.A.Sc. degree, both in Computer Engineering, from Huazhong University of Science and Technology, China, and the University of Toronto, Canada respectively; and the PhD degree in Computer Science from the Texas A&M University, USA. Since 1991 he has been at UNL, where he served as Vice Chair of the Department of Computer Science and Engineering (CSE) from 2001 to 2007 and is Professor of CSE. He is recently awarded a renewable 5-year term University Professorship at UNL, Willa Cather Professor of Computer Science and Engineering, effective August 2013. His areas of research emphasis include computer architecture, computer storage systems, high-performance computing, big data computing, and cloud computing. He has over 200 publications in major journals and international conferences in these areas. He has graduated 12 Ph.D. students who upon their graduations either landed academic tenure-track positions in Ph.D.-granting US institutions or were employed by major US IT corporations. Within the past 10 years he has secured $2.243-million NSF grants as PI, $2.5-million NSF grants as Co-PI, RMB49-million ($7.72-million) China’s NSF grants as Co-PI. He serves as an Associate Editor of the IEEE Transactions on Parallel and Distributed Systems, is a Senior Member of IEEE, a member of ACM. He has been on leave as a Program Director at the National Science Foundation since January 2013.
