1. User Interfaces for PSE's
   1. Elias Houstis
   2. Granville Sewell El Paso
   3. Robert Nelson LLNL/SPDC
   4. Candrajit Bajaj Purdue
2. Houstis Presentation
   1. *Scalability -- too many grid points to display
   2. *and in aerospace design, have 300,000 parameters for 10,000 programs
      1. -One user can't set all these
      2. -AI system to help
   3. *Computational servers as new library model
   4. *Softlab project develops virtual laboratory for two Purdue projects.
   5. *SciencePad -- Laboratory Notebook built on top of web browser
3. Bajaj Presentation
   1. *Working on Visible Human Project
   2. *Has his own environment SHASTRA
   3. *Used to design Prosthesis
   4. *Problem Solving in the large to support collaboration between groups of experts
4. PDE2D Sewell
   1. *PDE2D based on Protran
      1. -IMSL abandoned Protran
   2. *Protran was script based and translated into Fortran
   3. *PDE2D has an interactive Interface and skips script -- it generates readable Fortran
      1. -Interface is ascii question and answer -- not GUI
   4. *This Fortran repeats comments so code is self documenting -- Interesting
5. Graphical versus Scripting Interfaces
   1. *Visual C++ puts everything into icons -- Nelson considers this as a disaster
      1. -GUI should give you a menu access to complex set of scientific concepts
   2. *Thompson noted scripted Eagle grid generation system was not popular in Industry as they needed a GUI even though Eagle more fun
      -MSU built GUI on top of scripting system to make Eagle more acceptable
   3. *Purdue uses C++ and VX(?)
6. Questions from the audience - I
   1. *Do you need AI based reasoning techniques to customize interfaces for each different group of users?
   2. *PDE's have too many parameters to display all options
      1. -Need to arrange into subsets
   3. *What is Idiom that describes PSE environment that best represents scientific problem solving?
7. Questions from the Audience-- II
   1. *Sincovec notes that real problems require data from around the world -- advocates WebWork!
   2. *Require multiple cooperating laboratories
   3. *Need support for comparing computations with experimental results
      1. -So easy to go wrong as no guaranteed correct solution scheme for most real PDE's
      2. -Thompson says we have ethical need to make certain PSE's give reliable results
8. Questions from the
9. Audience-- III
   1. *Sherman says people seem to claim that all too specialized and so no viable commercial business plan
   2. *Thompson and Sherman say should hide grid -- this is a artifact and not the physical problem
