Develop general methodology
  • Define C CORBA wrapper for scientific codes, with "run method" and "display method" (preserve existing GUI if desired), and appropriate getparm/setparm methods
  • Language-independent model, since Fortran can interface to CORBA through C
  • Parallel computations trivial using host-node model and linking to host
  • RIB-like "library" information can be defined to facilitate sharing and reuse of "wrapped" computational modules
