Master Foilset for Fall 95 WebWork -- MetaComputing and Distributed Software Engineering
Given by Geoffrey C. Fox at Icase/HPDC95/HPCS95 on 15 September 95. Foils prepared 15 September 1995
|
This describes the forces motivating use of Web in MetaComputing
|
|
First the need for a pervasive technology base for HPCC which is otherwise a nonviable niche market.
|
|
The growing number of Web-enabled machines and the development of WebWindows giving the productivity tools needed for a true distributed HPCC software engineering environment
|
|
We describe the 3 layer model of WebWork
|
|
At the high end we describe our early example -- WebFlow and how this can be extended to a full WebHPL with mixed interpreted and compiled systems.
|
|
At the base level, we have the World-Wide Virtual Machine as a mesh of computationally extended web servers
|
|
At the Intermediate level, we propose WebScript to integrate VRML, PERL5 Java and similar domain specific scripting systems
|
This mixed presentation uses parts of the following base foilsets which can also
be looked at on their own!

The first High Level Example is WebFlow
- Think as Web Implementation of AVS or Khoros
- This also illustrates role of Java
HPCS95master 030 027 WebFlow Paradigm

Webworkaddons 008 029 Figure 7: Java demo (NPAC) --
WebFlow Editor prototype
Webworkaddons 015 030 Java Character Recognition Demo
-- The Letter W
More Ambitious is WebHPL (High Performance Language)
- Initially HPFCL with task parallelism done with Web
- Generally a hybrid Compiled/Interpreted Environment
CRPCWebWindows 021 031 WebHPL: HPCC Infrastructure for
WebWindows
CRPCWebWindows 022 032 WebHPL -- Integrating Compiler
and Interpreter Technologies
Software Project Manager Illustrates the Synergy between Software Engineering and Computing
- Java does both WebFlow Computing and WorkFlow analysis
HPCS95master 031 033 Software Project Manager --
Example of Agent Middleware

WebScript is Layer 2 Integration of Agents and Scripted Languages
- VRML is either a script for 3D graphics or a universal data structure
- Java is a script optimized for browsers and computing
