Abstract: The Kokkos based library Cabana, which has been developedin the Co-design Center for Particle Applications (CoPA), is usedfor the implementation of Multi-Particle Collision Dynamics (MPCD),a particle-based description of hydrodynamic interactions. It allows aperformance portable implementation, which has been used to study theinterplay between CPU and GPU usage on a multi-node system. As aresult, we see most advantages in a homogeneous GPU usage, but wealso discuss the extent to heterogeneous applications, using both CPUand GPU concurrently.
