Seyyidahmed Lahmer, Daniel Seibel, Srijeet Basu +9
Network simulation plays an important role in HPC/AI system research by enabling exploration of network architectures, communication strategies, and system configurations at scales…
Performance Evaluation of Fast Fourier Transforms on Emerging RISC-V Hardware with Vector Extension Support
Daniel Seibel, Kaveh Haghighi Mood, Jayesh Badwaik +3
This manuscript presents a performance evaluation of Fast Fourier Transform (FFT) implementations on emerging processors supporting the RISC-V Vector Extension (RVV 1.0). By introd…
Almost complete analytical integration in Galerkin BEM
Daniel Seibel
In this work, semi-analytical formulae for the numerical evaluation of surface integrals occurring in Galerkin boundary element methods (BEM) in 3D are derived. The integrals appea…
Boundary Element Methods for the Wave Equation based on Hierarchical Matrices and Adaptive Cross Approximation
Daniel Seibel
Time-domain Boundary Element Methods (BEM) have been successfully used in acoustics, optics and elastodynamics to solve transient problems numerically. However, the storage require…
