B Meson Semileptonic Form Factors from Unquenched Lattice QCD
Emel Gulez, Alan Gray, Matthew Wingate +3
The semileptonic process, B --> Ïl ν, is studied via full QCD Lattice simulations. We use unquenched gauge configurations generated by the MILC collaboration. These include the e…
Performance report and optimized implementations of Weather & Climate dwarfs on multi-node systems
Louis Douriez, Alan Gray, David Guibert +2
This document is one of the deliverable reports created for the ESCAPE project. ESCAPE stands for Energy-efficient Scalable Algorithms for Weather Prediction at Exascale. The proje…
A Lightweight Approach to Performance Portability with targetDP
Alan Gray, Kevin Stratford
Leading HPC systems achieve their status through use of highly parallel devices such as NVIDIA GPUs or Intel Xeon Phi many-core CPUs. The concept of performance portability across…
B semileptonic decays with 2+1 dynamical quark flavors
Emel Gulez, Christine Davies, Alan Gray +3
We study semileptonic B decays, using MILC dynamical configurations with . NRQCD heavy and AsqTad light quark actions are used. We obtain the semileptonic form factors $f_…
Performance report and optimized implementation of Weather & Climate Dwarfs on GPU, MIC and Optalysys Optical Processor
Cyril Mazauric, Erwan Raffin, Xavier Vigouroux +6
This document is one of the deliverable reports created for the ESCAPE project. ESCAPE stands for Energy-efficient Scalable Algorithms for Weather Prediction at Exascale. The proje…
Redesigning GROMACS Halo Exchange: Improving Strong Scaling with GPU-initiated NVSHMEM
Mahesh Doijade, Andrey Alekseenko, Ania Brown +2
Improving time-to-solution in molecular dynamics simulations often requires strong scaling due to fixed-sized problems. GROMACS is highly latency-sensitive, with peak iteration rat…
