Query: Multi-physics simulations using a hierarchical interchangeable software
  interface   We introduce a general-purpose framework for interconnecting scientific
simulation programs using a homogeneous, unified interface. Our framework is
intrinsically parallel, and conveniently separates all component numerical
modules in memory. This strict separation allows automatic unit conversion,
distributed execution of modules on different cores within a cluster or grid,
and orderly recovery from errors. The framework can be efficiently implemented
and incurs an acceptable overhead. In practice, we measure the time spent in
the framework to be less than 1% of the wall-clock time. Due to the unified
structure of the interface, incorporating multiple modules addressing the same
physics in different ways is relatively straightforward. Different modules may
be advanced serially or in parallel. Despite initial concerns, we have
encountered relatively few problems with this strict separation between
modules, and the results of our simulations are consistent with earlier results
using more traditional monolithic approaches. This framework provides a
platform to combine existing simulation codes or develop new physical solver
codes within a rich "ecosystem" of interchangeable modules.
