Abstract :
[en] 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 document is an update to ``An Overview of the
Trilinos project'' by Heroux et al. (ACM Transactions on Mathematical Software,
31(3):397-423, 2005). It 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. This paper also outlines the organization
of the Trilinos community and the contribution model to help onboard interested
users and contributors.
