Optimizing Staggered Multigrid for Exascale performance
Venkitesh Ayyar, Richard Brower, M. A. Clark +2
Adaptive multi-grid methods have proven very successful in dealing with critical slow down for the Wilson-Dirac solver in lattice gauge theory. Multi-grid algorithms developed for…
Gadget3 on GPUs with OpenACC
Antonio Ragagnin, Klaus Dolag, Mathias Wagner +5
We present preliminary results of a GPU porting of all main Gadget3 modules (gravity computation, SPH density computation, SPH hydrodynamic force, and thermal conduction) using Ope…
Pushing Memory Bandwidth Limitations Through Efficient Implementations of Block-Krylov Space Solvers on GPUs
M. A. Clark, Alexei Strelchenko, Alejandro Vaquero +2
Lattice quantum chromodynamics simulations in nuclear physics have benefited from a tremendous number of algorithmic advances such as multigrid and eigenvector deflation. These imp…
Conjugate gradient solvers on Intel Xeon Phi and NVIDIA GPUs
O. Kaczmarek, C. Schmidt, P. Steinbrecher +1
Lattice Quantum Chromodynamics simulations typically spend most of the runtime in inversions of the Fermion Matrix. This part is therefore frequently optimized for various HPC arch…
HISQ inverter on Intel Xeon Phi and NVIDIA GPUs
O. Kaczmarek, C. Schmidt, P. Steinbrecher +2
The runtime of a Lattice QCD simulation is dominated by a small kernel, which calculates the product of a vector by a sparse matrix known as the "Dslash" operator. Therefore, this…
