Computer Science Department Colloquium Series Presents: Professor David Du

Computer Science Department Colloquium Series Presents:

“Can Emerging Storage Technologies Help Solving Big Data Problems?”

 Professor David Du

University of Minnesota, Minneapolis

Qwest Chair Professor at the Computer Science and Engineering Department



Many challenges exist in current big data era. These include how to store enormous amount of data for a very long time, how to identify the relevant data from all the available data, and how to process relevant data efficiently. We intend to fully utilize the available data for making critical decisions to benefit individuals, business, and society. In this talk, we will introduce several emerging storage technologies including a new type of disk drives called Shingled Magnetic Recording (SMR) drives which has bigger capacity, an active storage device call Kinetic drive which can perform search and other functions by itself without going through servers, and Non-Volatile Memory (NVM) which blurs the boundary of memory and storage. The emerging NVM has recently generated quite a bit excitements. Due to its non-volatile property, it can be used as either main memory or storage. Flash memory-based solid state drives (SSD) have already replaced high performance hard disk drives (HDD). Other types of NVRAM like PCM, MRAM, and STT-RAM have the potential to replace DRAM as main memory.  We like to ask the following questions. Can these emerging technologies help solving big data problems? With the boundary of memory and storage becoming blurred, what are to be changed in computer architecture, operating systems and software/applications? How can we take advantages of these emerging technologies to meet some of the challenges from big data era?


David H.C. Du  – received his B.S. from National Tsing-Hua University in 1974 and the M.S. and Ph.D. degrees in computer science from the University of Washington, Seattle, in 1980 and 1981, respectively. He is currently the Qwest Chair Professor at the Computer Science and Engineering Department, University of Minnesota, Minneapolis and the Director of NSF I/UCRC Center Research in Intelligent Storage. He is an IEEE Fellow and a Fellow of Minnesota Supercomputing Institute. He has served as a member of Advisory Committee of Korean Computer Society, Sangdong University in China, IIS and CITI in Academic Sinica, III and ITRI in Taiwan.  He has done research in cyber security, sensor networks, multimedia computing, storage systems, high-speed networking, high-performance computing, and database design and CAD for VLSI circuits. His current research focuses on storage technologies/systems and vehicular networks. He has authored and co-authored more than 300 technical papers, including 130 referred journal publications. He has also graduated 60 Ph.D. and 100+ M.S. students in the past. He is currently served on a number of journal editorial boards. He has also served as guest editors for a number of journals including IEEE Computer, IEEE and Communications of ACM. He has served as Conference Chair and Program Committee Chair to several major conferences in multimedia, database, security and networking areas.
