The Trilinos core area includes packages that form the basic building blocks for Trilinos capabilities. This talk
will briefly introduce each package and demonstrate how these can be pulled together into an application. We will
cover the following packages. The Kokkos performance portability library provides data structures and parallel
algorithms that are performant on both CPU and GPU architectures. The Kokkos-Kernels library provides
performance portable BLAS and LAPACK routines. The Tpetra library provides MPI-based parallel distributed linear
algebra data structures built on Kokkos. The Teuchos library provides utilities for a common look and feel
across Trilinos packages, including a reference counted smart pointer, print utilities, timers and a parameter list
for user input. The Zoltan library provides parallel distributed load balancing tools. The PyTrilinos package
provides python wrappers for Trilinos capabilities. The Thyra package provides abstraction layers for writing
linear algebra, linear solvers and nonlinear solvers. The talk will conclude with examples of Trilinos capabilities
integrated into the Empire electromagnetic particle-in-cell code.
