Research software has been categorized in different contexts to serve different goals. We start with a look at what research software is, before we discuss the purpose of research software categories. We propose a multi-dimensional categorization of research software. We present a template for characterizing such categories. As selected dimensions,...
The term Research Software Engineer, or RSE, emerged a little over 10 years ago as a way to represent individuals working in the research community but focusing on software development. The term has been widely adopted and there are a number of high-level definitions of what an RSE is. However, the roles of RSEs vary depending on the institutional...
Researchers develop software to process or generate data to test their scientific hypotheses. Especially researchers from STEM disciplines (Science, Technology, Engineering, and Mathematics) validate their models through self-developed software prototypes. However, they do not necessarily have a programming or software engineering background. Moreo...
Research software has become a central asset in academic research. It optimizes existing and enables new research methods, implements and embeds research knowledge, and constitutes an essential research product in itself. Research software must be sustainable in order to understand, replicate, reproduce, and build upon existing research or conduct...

Most computational fluid dynamics (CFD) simulations require massive computational power, which is usually provided by traditional high-performance computing (HPC) environments. Often, simulations are executed on a massive number of CPU cores (O(1000)) that are hosted in a remote supercomputing center or an in-house supercomputing facility. Due to s...
Dieser Artikel stellt ein dynamisches Applikationsframework zur Berechnung von hydrodynamischen und hydrostatischen Problemen im Bereich des Küsteningenieurwesens vor. Die Berechnungsgrundlagen im Küsteningenieurwesen bilden komplexe empirische Formeln, die mithilfe dieser Applikation automatisiert gelöst und flexibel kombiniert werden können. Zu d...
Dieser Artikel präsentiert die Mechanismen der agilen Softwareentwicklung. Durch eine Gegenüberstellung ausgewählter, agiler Vorgehensmodelle wie dem Extreme Pro- gramming oder auch SCRUM versucht diese Arbeit ein tiefergehendes Verständnis über die Mechanismen der agilen Praktiken zu liefern. Darüber hinaus wird die Umsetzung agiler Me- thoden im...
In dieser Arbeit wird die Implementierung eines Gittergenerators zur Verwendung auf der Grafikkarte vorgestellt. Hierbei generierte Gitter dienen als Grundlage zur numerischen Berechnung von Strömungssimulationen, die ebenfalls auf der Grafikkarte durchgeführt werden. Die entstandene Applikation demonstriert eine effiziente und robuste Implementier...
Most computational fluid dynamics (CFD) simulations require massive computational power which is usually provided by traditional High Performance Computing (HPC) environments. Although interactivity of the simulation process is highly appreciated by scientists and engineers, due to limitations of typical HPC environments, present CFD simulations ar...
We develop a performance prediction model for a parallelized sparse lattice Boltzmann solver and present performance results for simulations of flow in a variety of complex geometries. A special focus is on partitioning and memory/load balancing strategy for geometries with a high solid fraction and/or complex topology such as porous media, fissure...
In this article we present an educational simulation tool, FlowSim 2007 CUDA edition, a computational steering application for interactive 2D flow simulation based on the lattice Boltzmann Method. The application combines a comfortable user interface as well as a convenient development platform on the one hand and a high performance flow solver on...

Kurzfassung: Mit dem .NET Framework stellt Microsoft seit knapp drei Jahren eine neue Plattform für die objektorientierte Entwicklung und Ausführung von Anwendungen zur Verfügung. Hierfür hält das Framework einige Neuerungen bereit, die die Anwen-dungsentwicklung komfortabler gestalten und die Ausführung des Codes u.a. sicherer machen. Am Beispiel...
