Unifying Economic and Language Models for Enhanced Sentiment Analysis of the Oil Market
Himmet Kaplan, Ralf-Peter Mundani, Heiko Rölke +2
Crude oil, a critical component of the global economy, has its prices influenced by various factors such as economic trends, political events, and natural disasters. Traditional pr…
Design and optimisation of an efficient HDF5 I/O kernel for massive parallel fluid flow simulations
Christoph Ertl, Jérôme Frisch, Ralf-Peter Mundani
More and more massive parallel codes running on several hundreds of thousands of cores enter the computational science and engineering domain, allowing high-fidelity computations o…
A high-performance interactive computing framework for engineering applications
Jovana Knežević, Ralf-Peter Mundani, Ernst Rank
To harness the potential of advanced computing technologies, efficient (real time) analysis of large amounts of data is as essential as are front-line simulations. In order to opti…
Dynamic load balancing strategies for hierarchical p-FEM solvers
Ralf-Peter Mundani, Alexander Düster, Jovana Knežević +2
Equation systems resulting from a p-version FEM discretisation typically require a special treatment as iterative solvers are not very efficient here. Applying hierarchical concept…
Computational steering of complex flow simulations
Atanas Atanasov, Hans-Joachim Bungartz, Jérôme Frisch +4
Computational Steering, the combination of a simulation back-end with a visualisation front-end, offers great possibilities to exploit and optimise scenarios in engineering applica…
Framework for the hybrid parallelisation of simulation codes
Ralf-Peter Mundani, Marko Ljucović, Ernst Rank
Writing efficient hybrid parallel code is tedious, error-prone, and requires good knowledge of both parallel programming and multithreading such as MPI and OpenMP, resp. Therefore,…
