scalable discretization strategy should be based on using a data-local method,
e.g., a flexible-order finite difference method for discretely approximating the
governing equations and imposing boundary conditions via fictitious ghost
points techniques as described in [7, 15]. Such an approach has several at-
tractive features from a scientific computing perspective. For example, finite
difference methods are among the simplest and most efficient methods due
to the use of structured grids and data structures. This results in low imple-
mentation and computational complexity which maps efficiently to mo ...
