We desribe the proposed next step of the "computer science" component of the Colliding Black Hole Grand Challenge |
DAGH (and HPF) provides a basic language technology which can be basis of a Problem Solving Environment (aka Toolkit) for this application |
We propose a Web based system using Java for an adaptive AVS like system manipulating DAGH components
|
We give examples of such Web Facilities |
In second part of talk we review Syracuse activities which include work on the PSE as well as particular modules for PSE including

Java provides a convenient way to build flexible graphics interfaces |
The screendump shows the message passing traffic and status of (36) parallel nodes used in a sorting algorithm |
In the example, the 36 threads are running the explicit algorithm on the client |
Alternatively and more generally, the threads are replaying a trace of the program which is or was running on a separate set of nodes |
If one uses Web Servers to control master parallel computation or more generally integrates Web into computing, these Web servers can naturally feed event traces into Java based display

Colors represent node status and links message-passing |
A sample VRML page produced by Black Hole Simulation group at NCSA and displayed by SGI WebSpace, cooperating with Netscape Navigator. |
A set of 3D spaces related to gravity research is represented as Netscape icons and linked to the corresponding VRML worlds. |
WebSpace window displays one of these spaces -- a space-time diagram for two black hole collision ('Pair of Pants' diagram) |
