Fusion von HPC und Data Analytics (HPC-DA)

Das ZIH erweitert seinen Hochleistungsrechner um Systemkomponenten für die Analyse komplexer großer Datenmengen. Die Erweiterung bietet den Forschenden mehr als 2 Petabyte Flash-Speicher mit einer Bandbreite von etwa 2 Terabyte/s, wobei der Flash-Speicher flexibel konfigurierbar ist und an allen vorhandenen ZIH-Rechenknoten genutzt werden kann. Für große Datenvolumen wird daneben ein Objekt-Speicher von 10 Petabyte bereitgestellt. Beide Lösungen werden von der Firma NEC geliefert. Als Schnittstelle von HPC und Data Analytics bietet „HPC-DA“ skalierbare virtuelle Forschungsumgebungen, die auf die Anforderungen der Anwender/-innen zugeschnitten sind. Die Rechenkapazität wird um 22 Power-9-Knoten der Firma IBM mit jeweils sechs Nvidia-V100-GPUs erweitert, die an die genannten Speichersysteme angebunden werden und damit eine der momentan leistungsfähigsten Machine-Learning-Infrastrukturen in Deutschland zur Verfügung stellen. Insgesamt bietet das System damit die Möglichkeit, verschiedene Technologien flexibel zu effizienten und individualisierbaren Forschungsinfrastrukturen zu kombinieren. Die Installation wird Nutzer/-innen aus ganz Deutschland offenstehen, deren HPC- und Big-Data-Anwendungsfälle in besonderer Weise von HPC-DA profitieren können. Der Produktionsbetrieb beginnt ab Ende 2018; Projektanträge können über das Antragsportal des ZIH https://hpcprojekte.zih.tu-dresden.de/da/ eingereicht werden.

The research paper Using Link Features for Entity Clustering in Knowledge Graphs has received the Best Research Paper Award of the 15th Extended Semantic Web Conference (ESWC) held in June 2018 in Heraklion, Greece. The paper describes the CLIP algorithm for entity clustering that substantially outperforms previous approaches and that can also be applied for repairing entity clusters. CLIP has been added to the FAMER tool, a system for parallel multi-source entity resolution based on Apache Flink. The awarded paper is authored by Alieh Saeedi, Eric Peukert and Erhard Rahm from the database group Leipzig and the Big Data Center ScaDS; Alieh presented the paper at the conference. The ESWC 2018 research track had 31 papers selected from 132 submissions so that the Best Research paper award represents a significant distinction.

4th International Summerschool for Big Data June 30th to July 6th 2018 in Leipzig

From June 30th to July 6th 2018 the two in Germany based Big Data Competence Centers ScaDS Dresden/Leipzig and BBDC are organizing the fourth international summer school on Big Data and Machine learnuing in its series of summer schools (20162017). The event aims at graduate students, Ph.D. students, researchers and practitioners  starting or being active in the fields of Big Data and machine Learning. Within the program, we offer inspiring insights into the area by selected keynotes from international experts combined with industrial talks.  Prior to the summer school, there will be a "streamline" hackathon for hands-on development of an application for real-time analytics of streaming data.  Furthermore, there will be plenty of opportunities to exchange ideas and to discuss the topics with other participants and speakers. The summer school also hosts several social activities such as a city walk and a dinner in a traditional restaurant.

ScaDS Dresden/Leipzig at CeBIT 2018

Also this year, ScaDS Dresden/Leipzig will continue to present Big Data related research topics at the IT conference and exhibition CEBIT, this year at the Hannover Exhebition Center from June 11 - 15 in Hannover. On the shared booth together with other universities of the Free State of Saxony, Saxony-Anhalt and the Free State of Thuringia we will be part of the TU Dresden exhibit and inform the public in particular about recent developments in Big Data application areas. ScaDS Dresden/Leipzig presentations will be accompanied with other research topics form the Center of Informations Services and High Performance Computing (ZIH) of the TU Dresden, the 5G Lab and the Cluster of Excellence Center for Advancing Electronics Dresden (cfaed).

In particular, ScaDS Dresden/Leipzig and ZIH will inform the interested public about highlights in its research activities, including amongst others:

  • Big Data and data intensive computing
  • Data analytics and data life cycle management
  • High Performance Computing, Distributed and Cloud Computing
  • Scalable software tools for application support and energy efficient computing

All visitors and interested attendees of the exhibit are very welcome to visit our boot at CEBIT (a detailed location will be published as soon as available).
