title = "Profiling and application of the multi-scale universal interface (MUI)",
abstract = "The aim of this paper is to test the scalability of the multi-scale universal interface (MUI) code coupling library. This has been done by coupling two independent synthetic solvers to one another, which are then given an embarrassingly parallel workload. The quantity of work done by each synthetic solver, and the amount of data transferred, is representative of a typical multi-physics coupled problem. Both volumetric coupling (where whole fields are transferred), and interface coupling (where several variables at the two-dimensional interface between three-dimensional meshes) are tested. It is shown that the multi-scale universal interface scales well to a minimum of O(104) MPI tasks. We also demonstrate the use of the MUI library in coupling a neutronics code (DYn3D) to a CFD code (Code Saturne). We demonstrate this coupling by simulating a simplified molten salt fast nuclear reactor.",
