Applied Continuous Integration, complemented by demonstration of Suresoft

Abstract TUDA (Maric, Schwarzmeier):

We will present two CI pipelines in use in our projects. One of them is used in an industrial research project with BOSCH. The other one is used for the development of an ALE-Interface-Tracking framework in OpenFOAM.

Both CI pipelines use advanced CI possibilities and are geared towards development of sustainable research software. We will talk about the possibilities of CI and the lessons learned from introducing a rigid CI testing approach to an existing complex software.

Abstract TUBS (Linxweiler, Marcus):

We will demonstrate the SURESOFT HPC-Workflow that combines the tools Singularity, HPC-Rocket and FieldCompare to enable easy integration of CI pipelines with HPC Clusters with regression testing to ensure reproducible computation results.

Presenting „Betty’s Research Engine“ (NFDI4Ing Service)

Abstract: Findability of research software is addressed by Betty’s (Re)Search engine, a service that allows users to search for existing research software tailored for specific applications, thereby minimizing duplicate implementation efforts. Recently, the front end of the live instance has been improved and the engine was enhanced by the possibility to export search results into the Open Research Knowledge graph (ORKG). The source code is now publicly hosted at Gitlab and its architecture is explained in detail in a preprint submitted to the Ing.Grid journal, complemented by a tutorial video on YouTube. To this day, the live engine was visited around 15000 times.

Presenting „NFDI4Ing JupyterHub“ (NFDI4Ing Service)

Abstract: The presentation introduces the JupyterHub instance of NFDI4Ing, its current state of development and possible future extensions. Furthermore, we will use examples to present possible applications of the JupyterHub that can be tried out live by the participants.

Towards Schemas for Reusable Benchmarks (NFDI4Ing Seed Fund)

Abstract: In fields such as Software Engineering, research contributions often evaluate novel software tools for problems by executing both them and prior tools on the same benchmark. Benchmarks combine data sets with metadata relevant to the tool’s operation, e.g., ground truths. They are usually gathered for each study from informal sources or communityspecific data sets. The absence of format standardization and a clear separation between benchmarks’ data and metadata hinders the reuse of benchmarks, particularly for aspects not anticipated by their authors. We present schemas as a solution. Schemas define a) reusable fundamental data formats and b) more specific metadata formats that can be easily combined with the data and each other. We examined a collection of diverse log files as a case study. To this end, we defined tentative schemas for data and metadata and converted the logs into the format defined by our schemas. The transformation is almost lossless and fully automatable, which shows promise for the approach.
