Octet baryon isovector charges from lattice QCD
Gunnar S. Bali, Sara Collins, Simon Heybrock +4
We determine the axial, scalar and tensor isovector charges of the nucleon, sigma and cascade baryons as well as the difference between the up and down quark masses, . We…
Scipp: Scientific data handling with labeled multi-dimensional arrays for C++ and Python
Simon Heybrock, Owen Arnold, Igor Gudich +2
Scipp is heavily inspired by the Python library xarray. It enriches raw NumPy-like multi-dimensional arrays of data by adding named dimensions and associated coordinates. Multiple…
Baryonic and mesonic 3-point functions with open spin indices
Gunnar S. Bali, Sara Collins, Benjamin Glässle +5
We have implemented a new way of computing three-point correlation functions. It is based on a factorization of the entire correlation function into two parts which are evaluated w…
Multiple right-hand-side setup for the DD-αAMG
Daniel Richtmann, Simon Heybrock, Tilo Wettig
The setup cost of a modern solver such as DD-αAMG (Wuppertal Multigrid) is a significant contribution to the total time spent on solving the Dirac equation, and in HMC it can even…
Adaptive algebraic multigrid on SIMD architectures
Simon Heybrock, Matthias Rottmann, Peter Georg +1
We present details of our implementation of the Wuppertal adaptive algebraic multigrid code DD-AMG on SIMD architectures, with particular emphasis on the Intel Xeon Phi processo…
QPACE 2 and Domain Decomposition on the Intel Xeon Phi
Paul Arts, Jacques Bloch, Peter Georg +15
We give an overview of QPACE 2, which is a custom-designed supercomputer based on Intel Xeon Phi processors, developed in a collaboration of Regensburg University and Eurotech. We…
