1. John Rice on PSE Examples
   1. *Text Processing -- compare Word, Troff or Tex
   2. *CAD Systems hide NASTRAN
   3. *MATLAB -- Underlying software in fact available to everybody
      1. -Gave nice language ala 1070's and support
      2. -language like mathematica
2. PDELab as an example
   1. *Large scope as collected 20 different solvers -- much more than other systems
   2. *Interesting script with mathematics notation
   3. *invokes decomposers for parallel partitioining
   4. *Developed specialized bioseparation environment
   5. *user interface models lab environment
3. History of PSE
   1. *Started in 1963 but abandonned as not enough computing power
   2. *Now technology allows
   3. *What about Kiowa and other histogramming packages
4. Software/Language
   1. *Define problem to be solved
   2. *PSE specific computational script
      1. -What is a script! John Rice agrees this is not defined
      2. -Not just an Interpreted Language
   3. *System Components
      1. -Control Program
      2. -Problem Specific Modules
      3. -Runtime Support Systems
      4. -Utilities
   4. *Analyses MATLAB and PDELAB in these terms
   5. *May not need one program that knows whats going on globally!
5. Parallelism
   1. *A focus of this workshop
   2. *Extreme solution is to develop optimal code with software tailored to exploit all possible optimizations
      1. -Possible as PSE typically generates code
   3. *Minimize user time not computer time
6. Questions
   1. *What about open architectues?
   2. *Mixed feelings as "open-ness" not used.
   3. *Claims developers will build software - not users
   4. *PSE's are general field but money comes from PDE parts of Arpa,NSF
   5. *What is a script! Not asked
