42. CITAR: citing and archiving of research environments in the HPC, approaches and challenges.

Scientific Track

Poster

The CITAR project (Citing and Archiving Research) aims to develop a new scientific service for long-term archiving and reuse of the research environments. Reproducibility of research data, on which scientific publications are based, stands for the project on the foreground. Archiving of virtual research environments can unsure that scientific experiments even after a long time from the first...

44. Dislocation nucleation in Au nanowires with stress gradients

Scientific Track

Poster

The dislocation nucleation in face-centered cubic (fcc) defect-scarce Au nanowires (NWs) is a sequence of Shockley partial dislocation nucleation at free surfaces of the facetted nanowires, which is considered as the deformation mechanisms at the onset of plasticity. The yield stresses from MD simulations are usually severely overestimated compared to the experimentally measured stresses. But...

40. Effect of chemical sublattice ordering on the slip systems in BCC High Entropy Alloys

Korbinian Ziegler

Scientific Track

Poster

High entropy alloys (HEA) are a new class of metallic alloys with more than four
approximately equimolar elements and are promising structural materials with partially
outstanding mechanical properties. To understand the mechanical behaviour of
HEAs it is essential to investigate their intrinsic dislocation deformation
mechanism and the associated kinetic signatures.
Experimental results as...

96. Nonequilibrium biomolecular simulations

Dr Steffen Wolf

Scientific Track

Poster

Nonequilibrium effects can be found at the core of biomolecular functions, such as signal and energy transport. Investigating these nonequilibrium effects in molecular dynamics simulations requires extensive computational hardware, such as provided by NEMO and BinAC: as the simulated processes are non-ergodic, observables of interest do not converge over time, and thus a large number of...

93. Performance of the bwHPC cluster in the production of μ → τ embedded events used for the prediction of background for H → ττ analyses

Sebastian Brommer

Scientific Track

Poster

In high energy physics, a main challenge is the accurate prediction of background events at a particle detector. These events are usually estimated by simulation. As an alternative, data-driven methods use observed events to derive a background prediction and are often less computationally expensive than simulation.
The $\tau$ lepton embedding method presents a data-driven method to...

41. The First SARA Service Prototype: Long-Term Access and Publishing of Research Software Artefacts.

Scientific Track

Poster

The SARA project (Software Archiving of Research Artefacts) focuses on the development of a new scientific service that allows long-term access and publication of research data and scientific software. The poster represents the project’s motivation and goals, as well as important core components and features of the first SARA service prototype.
The SARA server forms the core of the service,...
