Since the commissioning of the first petascale machine, Roadrunner, in 2009 at the Los Alamos
National Laboratory (LANL), the ability for physics codes at LANL to take advantage of accelerators
has provided utility and productivity improvements for code users. The ability to take advantage of an
accelerator, and more specifically general purpose graphics processing units (GPGPUs), will quickly
move from a productivity enhancement to absolutely necessary as more than 90% of the compute
capability of the El Capitan supercomputer at Lawrence Livermore National Laboratory (LLNL) will
only be accessed through effective use of its GPGPUs, a task which has traditionally been
accomplished with vendor specific software extensions such as CUDA or HIP. Many projects with
code bases ranging from large and established FORTRAN codes to new c++ based projects have
made the decision to use Kokkos as the tool that will enable effective use of LLNL's El Capitan
compute resources as well as future machines which could likely benefit from Kokkos's capabilities.
In this talk I will give an overview of several physics code projects at LANL and their usage of Kokkos.
