Performance and Explainability Requirements of Evolutionary Algorithms in Real-World Physics-Informed Optimization
Helena Stegherr, Michael Heider, Nils Meyer +7
Evolutionary computation offers a variety of tools to solve complex real-world optimization problems. However, research often focuses on smaller, simplified problems and optimizati…
The quantum harmonic oscillator in a dissipative bath of anyon pairs
Nils-Henrik Meyer, Axel Pelster, Michael Thorwart
We generalize the formalism of open quantum systems to introduce anyon baths. In particular, we work out a dissipative anyon bath composed of independent pairs of one-dimensional G…
MRHS multigrid solver for Wilson-clover fermions
Daniel Richtmann, Nils Meyer, Tilo Wettig
We describe our implementation of a multigrid solver for Wilson-clover fermions, which increases parallelism by solving for multiple right-hand sides (MRHS) simultaneously. The sol…
Grid on QPACE 4
Peter Georg, Nils Meyer, Stefan Solbrig +1
In 2020 we deployed QPACE 4, which features 64 Fujitsu A64FX model FX700 processors interconnected by InfiniBand EDR. QPACE 4 runs an open-source software stack. For Lattice QCD si…
ECM modeling and performance tuning of SpMV and Lattice QCD on A64FX
Christie Alappat, Nils Meyer, Jan Laukemann +4
The A64FX CPU is arguably the most powerful Arm-based processor design to date. Although it is a traditional cache-based multicore processor, its peak performance and memory bandwi…
Performance Modeling of Streaming Kernels and Sparse Matrix-Vector Multiplication on A64FX
Christie L. Alappat, Jan Laukemann, Thomas Gruber +4
The A64FX CPU powers the current number one supercomputer on the Top500 list. Although it is a traditional cache-based multicore processor, its peak performance and memory bandwidt…
