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…
Lattice QCD on upcoming Arm architectures
Nils Meyer, Dirk Pleiter, Stefan Solbrig +1
Recently Arm introduced a new instruction set called Scalable Vector Extension (SVE), which supports vector lengths up to 2048 bits. While SVE hardware will not be generally availa…
Level spacings for weakly asymmetric real random matrices and application to two-color QCD with chemical potential
Jacques Bloch, Falk Bruckmann, Nils Meyer +1
We consider antisymmetric perturbations of real symmetric matrices in the context of random matrix theory and two-color quantum chromodynamics. We investigate the level spacing dis…
QPACE -- a QCD parallel computer based on Cell processors
H. Baier, H. Boettiger, M. Drochner +32
QPACE is a novel parallel computer which has been developed to be primarily used for lattice QCD simulations. The compute power is provided by the IBM PowerXCell 8i processor, an e…
Status of the QPACE Project
H. Baier, H. Boettiger, M. Drochner +27
We give an overview of the QPACE project, which is pursuing the development of a massively parallel, scalable supercomputer for LQCD. The machine is a three-dimensional torus of id…
QCD on the Cell Broadband Engine
F. Belletti, G. Bilardi, M. Drochner +16
We evaluate IBM's Enhanced Cell Broadband Engine (BE) as a possible building block of a new generation of lattice QCD machines. The Enhanced Cell BE will provide full support of do…
