Query: A tight-coupling scheme sharing minimum information across a spatial
  interface between gyrokinetic turbulence codes   A new scheme that tightly couples kinetic turbulence codes across a spatial
interface is introduced. This scheme evolves from considerations of competing
strategies and down-selection. It is found that the use of a composite kinetic
distribution function and fields with global boundary conditions as if the
coupled code were one, makes the coupling problem tractable. In contrast,
coupling the two solutions from each code across the overlap region is found to
be more difficult due to numerical dephasing of the turbulent solutions between
two solvers. Another advantage of the new scheme is that the data movement can
be limited to the 3D fluid quantities, instead of higher dimensional kinetic
information, which is computationally more efficient for large scale
simulations on leadership class computers.
