A staggered-grid multilevel incomplete LU for steady incompressible flows
Sven Baars, Mark van der Klok, Jonas Thies +1
Algorithms for studying transitions and instabilities in incompressible flows typically require the solution of linear systems with the full Jacobian matrix. Other popular approach…
A Recursive Algebraic Coloring Technique for Hardware-Efficient Symmetric Sparse Matrix-Vector Multiplication
Christie L. Alappat, Georg Hager, Olaf Schenk +5
The symmetric sparse matrix-vector multiplication (SymmSpMV) is an important building block for many numerical linear algebra kernel operations or graph traversal applications. Par…
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…
CRAFT: A library for easier application-level Checkpoint/Restart and Automatic Fault Tolerance
Faisal Shahzad, Jonas Thies, Moritz Kreutzer +3
In order to efficiently use the future generations of supercomputers, fault tolerance and power consumption are two of the prime challenges anticipated by the High Performance Comp…
