Another paper accepted at CLOSER 2018

12.01.2018
We are happy to announce that our paper Comparison and Runtime Adaptation of Cloud Application Topologies based on OCCI was accepted as a short paper at the 8th International Conference on Cloud Computing and Services Science (CLOSER 2018). Within the paper, we define a models at runtime approach that matches the running and desired state of a cloud application topology to perform corresponding adaptation steps.

DFG grant for GAIUS project

03.01.2018
We are happy to announce that the DFG has granted our request for funding for the GAIUS project. The project will run for three years and focus on the usability and maintainability of the AUGUSTUS tool for the annotation of genomic sequences. More details on the project can be found on the project homepage. 

APSA Workshop at ICSE 2018

03.01.2018

Our group member Steffen Herbold is general chair of the 1st International Workshop on Anti-Patterns for Software Analytics (APSA) held in conjunction with the ICSE 2018. The goal of the workshop is to bring together researchers working on software analytics and discuss which anti-patterns their frequently observe in papers. In this sense, anti-patterns are problems with how experiments and research are conducted leading to weak or invalid findings. Examples may are bad performance indicators, wrong treatment of test data, or lack of statistical tests. 
 
The deadline for submissions is February 5th, 2018. Details regarding the submission can be found on the hompage of the workshop. 

Journal First Presentation at ICSE 2018

03.01.2018
We are happy to announce that we will present the findings of our our journal article A Comparative Study to Benchmark Cross-project Defect Prediction Approaches at the 40th International Conference on Software Engineering. Within the article, we systematically compare the research on cross-project defect prediction conducted between 2007 and 2015 and find that newer approaches do not really advance the state of the art and that a seldomly considered approach by Camargo Cruz and Ochimizu from 2009 outperforms all others. The presentation will be part of the Journal-First-Conference-Second track of the conference.

Paper accepted at CLOSER 2018

18.12.2017
We are happy to announce that our paper Model-Driven Configuration Management of Cloud Applications with OCCI was accepted for publication at the 8th International Conference on Cloud Computing and Services Science (CLOSER 2018). The paper is a joint work of our group members Fabian Korte and Jens Grabowski with the researchers Philippe Merle, Stéphanie Challita, and Faiez Zalila from INRIA, France and demonstrates how the OCCI standard can be extended for model-driven configuration management of cloud applications.

Webinar on Getting Started with ETSI TDL

14.11.2017
Philip Makedonski will be providing a live webinar on getting started with the Test Description Language (TDL), together with Martti Käärik from Elvior. This webinar walks the audience through the main ingredients of the TDL, standardized at the European Telecommunications Standards Institute (ETSI) with contributions from the Software Engineering for Distributed Systems Group, and demonstrates how to use tools from the TDL open source project (TOP) to start applying TDL.The public webinar will be streamed live online on November 21st at 16:00 CET. A recording of the webinar will be made available for subsequent viewing shortly after the end of the live stream. Find out how to join or stream the webinar on the ETSI events website.   

Gastvortrag: Software Engineering Challenges of the H2020 DEEP-EST Modular Supercomputing Architecture

06.11.2017

Herr Prof. Dr. Helmut Neukirchen der University of Iceland wird am 07.11.2017 um 16:00 Uhr (c.t.) im Seminarraum 2.101 des Instituts für Informatik einen Vortrag über das H2020-Projekt DEEP-EST halten. Gäste sind herzlich willkommen.
 
Vortragstitel: Software Engineering Challenges of the H2020 DEEP-EST Modular Supercomputing Architecture

Abstract: While Moore's law still gives as a doubling of the number of transistors in an integrated circuit every two years, this does not anymore yield as well an associated doubling of clock speed and performance per clock cycle every two years. Hence, the only way to speed-up nowadays computations is parallel processing. However, due to non-parallel overheads, parallel processing does not scale infinitely and the state-of-the-art High-Performance Computing (HPC) approach to achieve high processing speed are heterogeneousarchitectures, using accelerators such as Graphics Processing Units (GPUs) or Many Integrated Cores (MIC) in addition to general purpose Central Processing Units (CPUs). Existing HPC codes however need to be rewritten to exploit the accelerators. This talks give a brief overview on the heterogeneous, Modular Supercomputing Architecture (MSA) of the European H2020 research project DEEP-EST (Dynamical Exascale Entry Platform – Extreme Scale Technologies) and the resulting Software Engineering challenges.
