ISAAC - In Situ Animation of Accelerated Computations

Matthes, Alexander; Meyer, Felix; Pausch, Richard; Widera, René; Huebl, Axel; Gerber, Vincent; Zenker, Erik; Kosukhin, Sergey

Many computations like physics or biologists simulations these days run on accelerated hardware like CUDA GPUs or Intel Xeon Phi, which are itself distributed in a big compute cluster communicating over MPI. The goal of ISAAC is to visualize this data without the need to download it to the host...

Slice2Volume: Fusion of multimodal medical imaging and light microscopy data of irradiation-injured brain tissue in 3D.

Müller, Johannes; Suckert, Theresa; Beyreuther, Elke; Schneider, Moritz; Boucsein, Marc; Bodenstein, Elisabeth; Stolz-Kieslich, Liane; Krause, Mechthild; von Neubeck, Cläre; Haase, Robert; Lühr, Armin; Dietrich, Antje

The dataset contains comprehensive image data for a total of nine mice, which underwent normal tissue brain irradiation with 90 MeV protons.              In particular, the image data comprise cone-bem computed tomographies (CBCT), Monte Carlo beam transport simulations based on those CTs,...

Teaching ML in Compact Courses

Fouilloux, Anne; Steinbach, Peter

This talk summarizes the experiences made with teaching Machine Learning within compact events that stretch over several days to a week maximum. Both speakers explain pitfalls they were caught in as well as solutions they found. This talk was given at the Teaching Machine Learning workshop at...

Mmpxrt; X-ray spectrometer simulation code with a detailed support of mosaic crystals.

Smid, Michal; Pan, Xiayun; Falk, Katerina

This is a a newly developed ray tracing code called mmpxrt, dedicated to study and design x-ray crystal optics, with a special focus on mosaic crystal spectrometers. Its main advantage over other currently available ray tracing codes is that it includes detailed and benchmarked algorithm to...

C++ & Python API for Scientific I/O with openPMD

Koller, Fabian; Poeschel, Franz; Gu, Junmin; Huebl, Axel

openPMD is an open metadata format for open data workflows in open science. This library provides a common high-level API for openPMD writing and reading. It provides a common interface to I/O libraries and file formats such as HDF5 and ADIOS. Where supported, openPMD-api implements both serial...

Theory of three-magnon interaction in a vortex-state magnetic nanodot

Verba, Roman; Körber, Lukas; Schultheiß, Katrin; Schultheiß, Helmut; Tiberkevich, Vasil; Slavin, Andrei

This repository contains the data used to determine the numerical threshold fields for three-magnon scattering in a vortex-state disk used in our paper "Theory of three-magnon interaction in a vortex-state magnetic nanodot" published in Physical Review B.  For different excitation frequencies,...

Data for: The structure in warm dense carbon

Vorberger, Jan; Plageman, Kai-Uwe; Redmer, Ronald

The structure of the fluid carbon phase in the pressure region of the graphite, diamond, and BC8 solid phases is investigated. We find increasing coordination numbers with an increase in density. From zero to 30 GPa, the liquid shows a decrease of packing efficiency with increasing temperature....
