(R)SE challenges in HPC
Jonas Thies, Melven Röhrig-Zöllner, Achim Basermann
We discuss some specific software engineering challenges in the field of high-performance computing, and argue that the slow adoption of SE tools and techniques is at least in part…
Tensor Product Scheme for Computing Bound States of the Quantum Mechanical Three-Body Problem
Jonas Thies, Moritz Travis Hof, Matthias Zimmermann +1
We develop a computationally and numerically efficient method to calculate binding energies and corresponding wave functions of quantum mechanical three-body problems in low dimens…
Performance of the low-rank tensor-train SVD (TT-SVD) for large dense tensors on modern multi-core CPUs
Melven Röhrig-Zöllner, Jonas Thies, Achim Basermann
There are several factorizations of multi-dimensional tensors into lower-dimensional components, known as `tensor networks'. We consider the popular `tensor-train' (TT) format and…
