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.

Comment article accepted by IEEE Transactions on Software Engineering

11.09.2017
We are happy to announce that our article Comments on ScottKnottESD in response to “An Empirical Comparison of Model Validation Techniques for Defect Prediction Models” was accepted for publication by the IEEE Transactions on Software Engineering. The article discusses problems with the normality correction of the ScottKnottESD test. 

Paper accepted at Springer Empirical Software Engineering Journal

09.08.2017

We are happy to announce that our paper "Addressing Problems with Replicability and Validity of Repository Mining Studies through a Smart Data Platform" was accepted for publication by Springer Empirical Software Engineering.  Within this article, four major problems in the state of practice of software repository mining that threaten the external validity of research results, i.e., the generalizability of drawn conclussions, are discussed. This article is an extension to our MSR publication.
The pre-print of the article is available online at Springer. A free view-only version of the article is available here.

Paper accepted for IEEE Transactions on Software Engineering

13.07.2017

We are happy to announce that our paper A Comparative Study to Benchmark Cross-project Defect Prediction Approaches was accepted for publication by the IEEE Transactions on Software Engineering - the top journal for the field of software engineering. 
 
Within this article, we compared 24 approaches for cross-project defect prediction proposed between 2008 and 2015. Most of these approaches were never replicated or compared to each other before. Our suprising findings show that very little actual progress was made in the state of the the art since 2009, if we considered multiple performance metrics and data sets. 

The pre-print of the article is available in IEEE Xplore and thanks to the green open access policy of the IEEE on our homepage.
