APEnet+: a 3D toroidal network enabling Petaflops scale Lattice QCD simulations on commodity clusters
Roberto Ammendola, Andrea Biagioni, Ottorino Frezza +11
Many scientific computations need multi-node parallelism for matching up both space (memory) and time (speed) ever-increasing requirements. The use of GPUs as accelerators introduc…
Distance preconditioning for lattice Dirac operators
G. M. de Divitiis, R. Petronzio, N. Tantalo
We propose a preconditioning of the Dirac operator based on the factorisation of a predefined function related to the decay of the propagator with the distance. We show that it can…
Non-perturbative improvement of quark mass renormalization in two-flavour lattice QCD
Patrick Fritzsch, Jochen Heitger, Nazario Tantalo
We non-perturbatively determine the renormalization constant and the improvement coefficients relating the renormalized current and subtracted quark mass in O(a) improved two-flavo…
