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?

How hard should one try to build open systems allowing disparate paradigms?
  • This is essential in say manufacturing where need to integrate 10,000 existing programs in Excel, Lisp .. Fortran together
How important is ability to invoke general purpose languages (such as Fortran, CC++, HPF ..) as well as a script with domain specific constructs.
  • cf: NSF Blackhole project with HPF and more focused approachs -- latter are ahead as HPF slow!
General and most serious problem with all HPCC software -- how do we support system with hardware rapidly evolving and software (industry) support resources small
Role of packages such as Mathematica cf: SINAPSE

MATLAB -- note not parallel but very succesful
AVS -- different level of abstraction from MATLAB -- also succesful and not (correctly) parallel.
PDElab/ELLPACK and other partial differential equation packages
DSI / SIMNET and distributed event driven simulation for military applications
VRML and growing distributing interactive gaming applications
Global Arrays (Pacific Northwest Lab) -- very succesful toolkit for matrix formulated chemistry applications -- can they/should they extend to finer grain molecular dynamics
ASOP -- Multidisciplinary Design Systems -- and lessons from prototypes Engineous (GE), FIDO(Langley), NPSS(Lewis)
  • Note link to databases and need for wrappers for legacy systems
WebWork -- Boston NPAC -- use Web for (initially) coarse grain software integration
