• Data structures.

  • How to handle interaction of adjacent or contained subregions.

    • Is equivalence of higher order subregions required or useful?
    • Are the "TSTT":http://www.tstt-scidac.org/software/ 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.

<pre>

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.
