Application developers are confronted with three axes of increasing complexity going forward; increasing heterogeneity in computing platforms at all levels, increasing heterogeneity in solvers and data management, and moving existing code bases to future programming models. While the first two will dictate which future programming models may deliver the needed performance, the third will determine their adoption. However, it is clear that the infrastructure backbone of large scale Multiphysics software has to orchestrate data and task movement between devices. The lifecycle of scientific software is several times that of platforms, therefore, any orchestration mechanism must have flexibility and configurability to remain usable on future platforms. In this presentation I will outline a model of an orchestration framework and the demands that it will place on programming models and languages.
