Foil 27 Comparison of Communication/Linkage Models

From Master Set of Foils for 1996 Session of CPS615 PET Training Session DoD HPC Modernization UGC -- June 2 98. by Geoffrey C. Fox
Computing Systems like NPAC's WebFlow control flow of information between linked objects. For example, in dataflow model, user must supply routines to process input of data that drives a given module and output of data for other modules
TANGO supports shared objects and user supplies routines that read or write either
  • Total state of application or
  • Change in state of application
In each case one needs an API to object which can either be proprietary (as in AUTOCAD or ArcoInfo GIS) or generic as in CORBA or Web Middle tier linkage
