Alya towards Exascale: Optimal OpenACC Performance of the Navier-Stokes Finite Element Assembly on GPUs
Herbert Owen, Dominik Ernst, Thomas Gruber +4
This paper addresses the challenge of providing portable and highly efficient code structures for CPU and GPU architectures. We choose the assembly of the right-hand term in the in…
Analytical Performance Estimation during Code Generation on Modern GPUs
Dominik Ernst, Markus Holzer, Georg Hager +2
Automatic code generation is frequently used to create implementations of algorithms specifically tuned to particular hardware and application parameters. The code generation proce…
Opening the Black Box: Performance Estimation during Code Generation for GPUs
Dominik Ernst, Georg Hager, Markus Holzer +2
Automatic code generation is frequently used to create implementations of algorithms specifically tuned to particular hardware and application parameters. The code generation proce…
Performance Engineering for Real and Complex Tall & Skinny Matrix Multiplication Kernels on GPUs
Dominik Ernst, Georg Hager, Jonas Thies +1
General matrix-matrix multiplications with double-precision real and complex entries (DGEMM and ZGEMM) in vendor-supplied BLAS libraries are best optimized for square matrices but…
Benefits from using mixed precision computations in the ELPA-AEO and ESSEX-II eigensolver projects
Andreas Alvermann, Achim Basermann, Hans-Joachim Bungartz +30
We first briefly report on the status and recent achievements of the ELPA-AEO (Eigenvalue Solvers for Petaflop Applications - Algorithmic Extensions and Optimizations) and ESSEX II…
Chebyshev Filter Diagonalization on Modern Manycore Processors and GPGPUs
Moritz Kreutzer, Georg Hager, Dominik Ernst +3
Chebyshev filter diagonalization is well established in quantum chemistry and quantum physics to compute bulks of eigenvalues of large sparse matrices. Choosing a block vector impl…
