Software Development Aspects of Integrating Linear Algebra Libraries
Marcel Koch, Tobias Ribizel, Pratik Nayak +3
Many scientific discoveries are made through, or aided by, the use of simulation software. These sophisticated software applications are not built from the ground up, instead they…
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…
Porting a sparse linear algebra math library to Intel GPUs
Yuhsiang M. Tsai, Terry Cojean, Hartwig Anzt
With the announcement that the Aurora Supercomputer will be composed of general purpose Intel CPUs complemented by discrete high performance Intel GPUs, and the deployment of the o…
Ginkgo -- A Math Library designed for Platform Portability
Terry Cojean, Yu-Hsiang "Mike" Tsai, Hartwig Anzt
The first associations to software sustainability might be the existence of a continuous integration (CI) framework; the existence of a testing framework composed of unit tests, in…
Evaluating the Performance of NVIDIA's A100 Ampere GPU for Sparse Linear Algebra Computations
Yuhsiang Mike Tsai, Terry Cojean, Hartwig Anzt
GPU accelerators have become an important backbone for scientific high performance computing, and the performance advances obtained from adopting new GPU hardware are significant.…
A Survey of Numerical Methods Utilizing Mixed Precision Arithmetic
Ahmad Abdelfattah, Hartwig Anzt, Erik G. Boman +22
Within the past years, hardware vendors have started designing low precision special function units in response to the demand of the Machine Learning community and their demand for…
Ginkgo: A Modern Linear Operator Algebra Framework for High Performance Computing
Hartwig Anzt, Terry Cojean, Goran Flegar +6
In this paper, we present Ginkgo, a modern C++ math library for scientific high performance computing. While classical linear algebra libraries act on matrix and vector objects, Gi…
Preparing Ginkgo for AMD GPUs -- A Testimonial on Porting CUDA Code to HIP
Yuhsiang M. Tsai, Terry Cojean, Tobias Ribizel +1
With AMD reinforcing their ambition in the scientific high performance computing ecosystem, we extend the hardware scope of the Ginkgo linear algebra package to feature a HIP backe…
Evaluating Abstract Asynchronous Schwarz solvers on GPUs
Pratik Nayak, Terry Cojean, Hartwig Anzt
With the commencement of the exascale computing era, we realize that the majority of the leadership supercomputers are heterogeneous and massively parallel even on a single node wi…
