Detrimental task execution patterns in mainstream OpenMP runtimes (2024)
Presentation / Conference Contribution
Weinzierl, T., Tuft, A., & Klemm, M. (2024, September). Detrimental task execution patterns in mainstream OpenMP runtimes. Presented at IWOMP 2024, Perth, Australia

The OpenMP API offers both task-based and data-parallel concepts to scientific computing. While it provides descriptive and prescriptive annotations, it is in many places deliberately unspecific how to implement its annotations. As the predomina...

Hindustani raga and singer classification using 2D and 3D pose estimation from video recordings (2024)
Journal Article
Clayton, M., Li, J., Clarke, A., & Weinzierl, M. (online). Hindustani raga and singer classification using 2D and 3D pose estimation from video recordings. Journal of New Music Research, 1-16. https://doi.org/10.1080/09298215.2024.2331788

Using pose estimation with video recordings, we apply an action recognition machine learning algorithm to demonstrate the use of the movement information to classify singers and the ragas (melodic modes) they perform. Movement information is derived... Read More about Hindustani raga and singer classification using 2D and 3D pose estimation from video recordings.

Impact of Inner Heliospheric Boundary Conditions on Solar Wind Predictions at Earth (2020)
Journal Article
Gonzi, S., Weinzierl, M., Bocquet, F., Bisi, M., Odstrcil, D., Jackson, B., Yeates, A., Jackson, D., Henney, C., & Nikolos Arge, C. (2021). Impact of Inner Heliospheric Boundary Conditions on Solar Wind Predictions at Earth. Space Weather, 19(1), https://doi.org/10.1029/2020sw002499

Predictions of the physical parameters of the solar wind at Earth are at the core of operational space weather forecasts. Such predictions typically use line-of-sight observations of the photospheric magnetic field to drive a heliospheric model. The...

Quasi-matrix-free hybrid multigrid on dynamically adaptive Cartesian grids (2018)
Journal Article
Weinzierl, M., & Weinzierl, T. (2018). Quasi-matrix-free hybrid multigrid on dynamically adaptive Cartesian grids. ACM Transactions on Mathematical Software, 44(3), Article 32. https://doi.org/10.1145/3165280

We present a family of spacetree-based multigrid realizations using the tree’s multiscale nature to derive coarse grids. They align with matrix-free geometric multigrid solvers as they never assemble the system matrices, which is cumbersome for dynam...

Impact of Non-potential Coronal Boundary Conditions on Solar Wind Prediction (2017)
Report
Weinzierl, M., Bocquet, F.-X., & Yeates, A. R. (2017). Impact of Non-potential Coronal Boundary Conditions on Solar Wind Prediction. [No known commissioning body]

Predictions of the solar wind at Earth are a central aspect of space weather prediction. The outcome of such a prediction, however, is highly sensitive to the method used for computing the magnetic field in the corona. We analyze the impact of replac...

The proposed Carrington-L5 mission would bring instruments to the L5 Lagrange point to provide us with crucial data for space weather prediction. To assess the importance of including a magnetograph, we consider the possible differences in non-potent...
