• Data structures.
  • How to handle interaction of adjacent or contained subregions.
    • Is equivalence of higher order subregions required or useful?
    • Are the TSTT Geometry and Mesh specifications helpful?

    Poul has looked at this and likes their approach, but it lacks details.

  • Examples from Poul.

  A few simple examples were presented by Poul on the white board - hopefully these will make it to the web later...but for now some asci art of what was drawn on the white board.

An Ensemble
   Ensemble
      name:
      dimension: n
      children: ensemble(dimension=n)
      boundary: ensemble (dimension=(n-1))
      links:
eg. A single element
             e1
     p1 o----------o p2
        ensemble
             name:e1
             dimension:1
             children:{}
             boundary:{p1,p2}
             links:{}
eg. Connected elements
                 e12
     p1 o-----------o------------o p3
                    p2
           /                 \
    p1 o------o p2    p2 o-----------o p3
        ensemble
             name:e12
             dimension:1
             children:{e1, e2}
             boundary:{p1, p3}
             links{{p1, e1.p1}
                   {p2, e1.p2}
                   {p2, e2.p1}
                   {p3, e2.p2}} 

• Where is shared data stored? Distributed database?

• Development framework.
  • What testing framework are we going to use?
  • How are we going to develop code?
  • subprojects for development of distributed parallelization

  Chris and Karl agree on the matrix vector multiply.

  No agreement yet on the databasing aspect.
