New preprint on the software library Trilinos

We are happy to announce our new preprint on the software library Trilinos.

Trilinos is a community-developed, open-source software framework that facilitates building large-scale, complex, multiscale, multiphysics simulation code bases for scientific and engineering problems. Since the Trilinos framework has undergone substantial changes to support new applications and new hardware architectures, this preprint, entitled “Trilinos: Enabling Scientific Computing across Diverse Hardware Architectures at Scale”, describes the design of Trilinos, introduces its new organization in product areas, and highlights established and new features available in Trilinos. Particular focus is put on the modernized software stack based on the Kokkos ecosystem to deliver performance portability across heterogeneous hardware architectures. It also outlines the organization of the Trilinos community and the contribution model to help onboard interested users and contributors.

IMCS members Dr.-Ing. Matthias Mayr and Max Firmbach are long-standing contributors to Trilinos, in particular to its MueLu package for algebraic multigrid (AMG) methods.
