Start of the lectures

The following courses start this week

  • Advanced Query Processing in Database Systems (Monday at 11:10am)
  • Information Retrieval (Monday at 2:50pm)
  • Scalable Data Management (Monday at 1pm)
  • Scalable Data Engineering (Monday at 1pm)
  • Pro-/Hauptseminar Kick-off (Tuesday at 1pm)

The internships (Komplex-/Master-/Forschungspraktikums) start next week.

KP/FP DB-Systemarchitektur SS2021

Im Komplex-/Forschungspraktikum “Hands-on hashing” werden die teilnehmenden Studierenden den Einfluss von Daten und Dateneigenschaften auf verschiedene Hash-Funtkionen strukturiert untersuchen. Bei Interesse bitte bei Dirk Habich oder Johannes Pietrzyk per E-Mail anmelden.

Gremien brauchen mehr beteiligte Studierende

Der Fachschaftsrat darf in der kommenden Legislatur wieder zahlreiche Mitglieder für Gremien zur studentischen Mitbestimmung entsenden. In diesen Gremien kannbeispielsweise direkter Einfluss auf die Überarbeitung von Studienordnungen und die Berufung neuer Professorinnen und Professoren genommen werden. Leider haben wir nur sehr wenige Mitglieder aus den Masterstudiengängen, sodass wir in der Vergangenheit nicht alle diese Gremien mit Studierenden der jeweiligen Fächer besetzen konnten.
Ausgeschriebene Gremien:

Falls ihr erfahren wollt, wie und wo ihr euch für euren Studiengang einsetzen könnt, kommt zur Gremienvorstellung am Freitag, dem 18.12.2020
18:30 Uhr. Das Treffen findet im BBB statt:

Forschungs- und Komplexpraktikum DB-Grundlagen WS 2019/2020

In the coming winter term WS 2019/2020, we offer a new internship (Forschungs- und Komplexpraktikum) on SIMD programming in database systems. In particular, we will have a deep dive using a tutorial at the beginning and then, we will enhance our developed Template Vector Library. More information can be found at the internship website or in the following pdf.

Best Paper Award@DATA 2018

We are happy to announce that our paper „Column Scan Optimization by Increasing Intra-Instruction Parallelism“ written by Nusrat Jahan Lisa, Annett Ungethüm, Dirk Habich, Nguyen Duy Anh Tuan, Akash Kumar, and Wolfgang Lehner has been awarded with the Best Paper of the 2018 DATA conference in Porto, Portugal.

Paper@ISITA 2018

We are delighted to announce that our paper „Lower Bound-oriented Parameter Calculation for AN coding“ written by Juliana Hildebrandt, Till Kolditz, Dirk Habich, and Wolfgang Lehner has been accepted at the International Symposium on Information Theory and Its Applications (ISITA). ISITA is the leading conference on information theory.

 

Abstract: The hardware as well as software communities have recently experienced a shift towards mitigating bit flips issues in software, rather than completely mitigating only in hardware. For this software error mitigation, arithmetic error coding schemes like AN coding are increasingly applied because arithmetic operations can be directly executed without decoding and bit flip detection is provided in an end-to-end fashion. In this case, the encoded data words are computed by multiplying a constant integer value A onto each original data word. To reliably detect b bit flips in each code word, the value A has to be well-chosen, so that a minimum Hamming distance of b+1 can be guaranteed. However, the value A depends on the data word length as well as on the desired minimum Hamming distance. Up to now, a very expensive brute force approach for computation of the value for A is applied. To tackle that in a more efficient way, we present a lower bound-oriented approach for this calculation in this paper. 

Paper@ADMS 2018

We are happy to announce that our joint paper with the processor design group of Akash Kumar has been accepted at the ninth International Workshop on Accelerating Analytics and Data Management Systems Using Modern Processor and Storage Architectures (co-located to VLDB). The paper presents a column scan accleration approach for hybrid CPU-FPGA systems.

SIGARCH Post

In a recent post on SIGARCH about Near Data Computing from a Database Systems Perspective written by Spyros Blanas, our work on resilient data storage and query processing is mentioned as an highlight and important future topic.
