WebWork is based on a three-layer architecture shown in figure 2, including: World_Wide Virtual Machine (WWVM) in the (bottom) layer 1, Middleware layer 2 of agents, wrappers, mediators etc., and high level programming environments (e.g. HPFCL) and user interfaces (e.g. WebFlow) in the (top) layer 3.
All base WebWork concepts can be implemented in terms of today's Web technologies (HTTP, MIME, CGI) and a prototype is under development at NPAC.
The overall design is open and ready to upgrade the existent (e.g. browsers or servers) and include new (e.g. agents or distributed object brokers) Internet/Web technologies
One starting point for the WebWork construction is provided by NPAC WebTools -- a CGI-extended Web server with enhanced content authoring and database navigation functionalities. WebTools Server is used as a prototype WebWork node server.

NPAC WebTools is a CGI-extended Web server that offers a HyperWorld based metaphor for organized content authoring and navigation, currently implemented in terms of the following tools: HyperWorld Manager, HyperWorld Navigator, On-Line HTML Editor, WebMail and CASE tools for HySource Worlds authoring.
HyperWorld Manager offers database management support for the server document tree, integrated with browser GUI tools for remote file/document and directory/folder handling (create, destroy, copy etc.). The model assures concurrency control, atomicity and integrity of the document datatbase.
  • Compare to File Manager in MS(becomes Web)Windows and simple UNIX shell cp mv rm commands. Directory structure is (crude) database structure built into UNIX. WebWindows has much much more powerful natural database support.

Foil 28 Web Productivity Tools and Virtual Software Laboratory (VSL)

From Master Foilset for HPC at the Crossroads Keynote HPCS95 Symposium -- July 10-12 Montreal Canada. * See also color IMAGE
Full HTML Index
NPAC WebTools can be viewed as an instance of Web Productivity Tools (navigators, editors, databases), developed collectively by the Internet/Web community.
We view these emergent open tools as central to develop and maintain Web based World-Wide Metacomputing.
Software exchange and integration tools are urgently needed. Without it, 'pervasive Web' will become soon too complex to maintain and will be dominated by closed corporate products.
One such attempt is made by the HySource CASE package in NPAC WebTools. So far, we developed HyPerl World (Screen 3) of the WebTools source code and we now integrate it with Java (Screen 4) in the form of HyJava World (Screen 5)
These tools will evolve towardsVirtual Software Laboratory -- a collective distributed CASE framework for virtual corporation of WebWork developers.

WebWork pilot project is a collaboration between NPAC, Boston University and Cooperative Systems Corporation, MA. It will prototype a candidate VSL, WWVM, Java based user interfaces, and port selected Grand/National Challenge applications to this platform.
The project will use NPAC WebTools to bootstrap the software process and will prototype WWVM in terms of current Web technologies (Screen 1)
Technically, early WWVM will include existent Web Servers with add-on CGI (Perl) scripts that build server-to-server communication and offer document database management, and module publication and linkage/instantiation support.
This base model will be further extended and refined by using and driving evolving Web technologies. For example, the disk-based model in Screen1a will likely evolve towards memory-mapped model based on multi-threaded interpreted compute-servers (Screen 1b)

User-level WebWork metaphor is given by WebFlow -- a distributed dataflow model built in terms of WebWork modules and MIME object/document communication channels.
  • Think as Web versions of AVS or Khoros
WebWork users will build and control distributed computing applications (compute-webs) using Web browsers based visual interactive editors and monitors.
We are currently prototyping such WebFlow front-ends at NPAC using Java/HotJava model. WebWork modules are represented by Java threads (Screen 6) and visualized as interactive interconnected icons (Screen 7)

Full HTML Index
One current WebWork/WebFlow application, prototyped at NPAC, is Software Project Manager (Screen 8). Each software developer runs his/her WebTools server and uses HySource CASE tools. These servers are WWVM-connected to agent and manager servers. Agent server receives automatic notifications from developers servers on each software volume update, and uses customizable thresholds to decide when to fire a report to the manager or a deadline reminder to a developer.
Software Project Manager tools contains a simple agent server that mediates between client/consumer ( here manager) and servers/producers (here developers).

Foil 32 General WebScript and Agents

From Master Foilset for HPC at the Crossroads Keynote HPCS95 Symposium -- July 10-12 Montreal Canada. * See also color IMAGE
Full HTML Index
More generally, this Middleware Layer 2 will be rather complex and populated by a spectrum of proprietary (e.g. Telescript, ScriptX, CORBA) and public (e.g. Perl, Tcl, Harvest, Java, VRML) scripted languages, brokers, agents, wrappers, mediators etc. see Screens
In WebWork, we refer collectively by WebScript to the whole ensable of these models.
At the current stage, it isn't clear if WebScript as a common intermediate language is a practical concept. An alternative is to live in the multi-language Web medium and emply interoperability agents to translate between various protocols.
Practical initial implementation platfrom for this dual approch is provided in WebWork by an integrated collection of WebTools CASE tools based HySource Worlds for various languages.

Full HTML Index
WebWork Interpolates and Integrates pervasive Web HPCC and (nonHPCC) commercial software as in following table comparing computing concepts in three "worlds"; HPCC -- Commercial mainstream -- Web
Current Web model needs computational extensions for banking/financial applications, manufacturing, interactice shopping/videogames etc
HPCC can provide Web both parallel computing programming models, libraries and language/runtime concepts which coordinate components of distributed or parallel system
HPCC needs the Web (or equivalent) to give it viable distributed computing and software engineering base
The Web interpolates between "flaky" research software and solid but closed corporate solution. Clear trend away from proprietary towards open software models.

A set of manufacturing companies -- Rockwell International, Northrop Grumman, McDoinnell Douglas, General Electric and General Motors is studying the NII implications for a particular MAD system "Affordable Systems Optimization Process" (ASOP)
Interesting parameters are that next major aircraft to be built could involve:
  • 6 major companies and 20,000 smaller supplier subcontractors
  • Number of engineers involved is about:
    • 50 at conceptual design
    • 200 at preliminary design
    • 2000 at final design
    • upto 10,000 in manufacturing and development
  • The design could involve upto 10,000 separate programs running in small linked clusters which vary from
    • Airflow simulation around plane to
    • expert system to plan location of inspection port to minimize maintenance costs
  • Critical is configuration management and system database
