## Dyablo: A simulation code for astrophysics fluids with adaptive mesh refinement with Kokkos
41+
42+
*Arnaud Durocher, Maxime Delorme, CEA-Saclay, IRFU/DEDIP/LILAS*
43+
44+
Dyablo is a new code for the simulation of astrophysical plasmas on exascale architectures using Adaptive Mesh Refinement. It is built from the ground up to target new and upcoming Exascale supercomputers with a new codebase in C++ using Kokkos. Dyablo is based on modern software engineering principles to allow "separation of concerns" and collaboration between HPC engineers and physicists through abstract interfaces and modularity. Although Dyablo is still in development, the code is now deployable and usable on all major (French) supercomputers.
45+
46+
We will present Dyablo, how it's made and what challenges had to be resolved for AMR on GPUs. We will also present two physical problems we resolve with Dyablo in solar physics and cosmology.

## Kokkos Resilience
41+
42+
*Nic Morales, Sandia National Lab.*
43+
44+
Resiliency against runtime errors, either through software bugs or hardware failures, is an essential component for any long-running scientific application. Kokkos Resilience is an experimental framework for adding resiliency to existing Kokkos codes. In this Kokkos Tea Time talk, I will provide an overview of Kokkos Resilience, including its capabilities for automating and tracking data structures for checkpoint/restart and detecting silent data corruption. I will also talk about future directions, including closer integration with Kokkos Tools and fault-tolerant MPI.

## Kokkos MPI Interop for all
41+
42+
We will present a new effort to provide a standard wrapper library to ease the use of MPI in Kokkos applications.
43+
We will describe the main short-term and long-term goals and give an overview of the code development.
44+
We also want to collect your use cases to ensure this new library will fit the needs of the various Kokkos or soon-to-be Kokkos applications.
