Need to define terms more precisely:
  • Does Language refer to fine grain operations/parallelism as in HPF
  • Does Environment refer to coarse grain parallelism as seen in AVS or Khoros?
  • Is "Software Bus" same thing as coarse grain software integration?
  • Does a scripting (interpreted) language such as PERL (an environment for document manipulation) or Visual Basic encompass both terms?
  • Does Parallel include Distributed? What is "Virtual" ?
What are requirements?
  • At system level -- metacomputers, and/or MPP's, and/or PC's ...
  • At Application level -- fields include Partial Differential Equations, Image Processing .. Distributed Simulation as in SIMNET .. DeskTop Publishing?
