Presentation:
Next-Generation Hardware for Big Data Management – Why we should care!

Recent hardware developments have touched almost all components of a computing system: the existence of many and potentially heterogeneous cores, the availability of volatile and non-volatile main memories with an ever growing capacity, and the emergence of economically affordable, high-speed/low-latency interconnects are only a few prominent examples. Every single development as well as their combination has a massive impact on the design of modern Big Data systems from different perspectives. Within this lecture, we will first give an overview of relevant hardware trends followed by a discussion on the impact for data management systems from a performance, robustness, as well as energy efficiency perspective. After attending this lecture, the participants should have a detailed understanding of recent hardware developments and their impact on the architecture of data management systems. The participants should also be able to pinpoint interesting starting points for further research activities.

Bio

Prof. Dr.-Ing. Wolfgang Lehner is full professor and head of the database technology group at Technische Universität Dresden (TU Dresden), Germany. He received his Master’s degree in Computer Science in 1995 from University of Erlangen-Nuremberg. He continued his studies as research assistant at the database system group until 1998, when he earned his Ph.D. degree (Dr.-Ing.) with a dissertation on optimization of aggregate processing in multidimensional database systems. Thereafter (11/1998) he joined the Business Intelligence (BI) group at the IBM Almaden Research Center in San Jose (CA), where he was involved in projects on adding materialized view support and multiple query optimization techniques to the core engine of the IBM DB2/UDB database system. After his return to Germany, he again joined the database system group at University of Erlangen-Nuremberg as senior researcher. Together with his group, he initiated comprehensive research in exploiting database technology to support complex message-based notification systems. From 10/2000 to 2/2002, Wolfgang Lehner was on a temporary assignment at the University of Halle-Wittenberg holding the professorship for database systems. In 7/2001 he finished his habilitation with a thesis on subscription systems and was therefore awarded with the venia legendi. Since 10/2002, Prof. Lehner has been conducting his research, teaching his students, and is involved in multiple industrial projects at the TU Dresden. Wolfgang Lehner was temporarily visiting scientist at Microsoft Research in Redmond (WA), at GfK Nuremberg, at SAP Walldorf, and at SAP Palo Alto. Wolfgang Lehner is a member of the Review Board on Computer Science of DFG (German Research Foundation). Since 2014, Wolfgang Lehner is a member of Academia Europaea (The Academy of Europe).
