<scp>Ginkgo</scp> : A Modern Linear Operator Algebra Framework for High Performance Computing

In this article, we present Ginkgo , a modern C++ math library for scientific high performance computing. While classical linear algebra libraries act on matrix and vector objects, ’s design principle abstracts all functionality as “linear operators,” motivating the notation of operator library.” current focus is oriented toward providing sparse graphics processing unit (GPU) architectures, but given design, can be easily extended to accommodate other algorithms hardware architectures. We introduce sophisticated software architecture that separates core from architecture-specific backends provide details extensibility sustainability measures. also demonstrate usability by examples how use its inside MFEM deal.ii finite element ecosystems. Finally, offer practical demonstration state-of-the-art GPU
