Interface for Sparse Linear Algebra Operations
Ahmad Abdelfattah, Willow Ahrens, Hartwig Anzt +32
The standardization of an interface for dense linear algebra operations in the BLAS standard has enabled interoperability between different linear algebra libraries, thereby boosti…
BDDC Preconditioning on GPUs for Cardiac Simulations
Fritz Goebel, Terry Cojean, Hartwig Anzt
In order to understand cardiac arrhythmia, computer models for electrophysiology are essential. In the EuroHPC MicroCARD project, we adapt the current models and leverage modern co…
FRSZ2 for In-Register Block Compression Inside GMRES on GPUs
Thomas Grützmacher, Robert Underwood, Sheng Di +2
The performance of the GMRES iterative solver on GPUs is limited by the GPU main memory bandwidth. Compressed Basis GMRES outperforms GMRES by storing the Krylov basis in low preci…
Fast Truncated SVD of Sparse and Dense Matrices on Graphics Processors
Andres E. Tomas, Enrique S. Quintana-Orti, Hartwig Anzt
We investigate the solution of low-rank matrix approximation problems using the truncated SVD. For this purpose, we develop and optimize GPU implementations for the randomized SVD…
