"Every" Business Office, Every doctor's Office, "Every" school desk, "Every" home(potential patient) (approximately any home on cable) will have a two-way high speed link to the NII
  • about 10 Megabits/second compared to
  • about 10 Kilobits/second for a modem (14.4 kbit/sec)
What does this factor of 1000 increase in performance do for the home?
  • TV + Settop Unit becomes Computer (analog) (interactive digital)
  • Modem & home PC supporting text interfaces becomes interactive full (VHS Þ HDTV resolution) video receiving unit
  • Interactive implies that you can choose what you want when you want it.
These consumer developments will drive MPP use

Like UNIX or MS-DOS or Windows 3.1(NT,95), WebWindows is an operating system for a "computer"
The "computer" is a metacomputer consisting of the 20,000 Webservers (currently--eventually hundreds of millions) on Internet for the World Wide Web
WebWindows can also be used for the metacomputer (collection of heterogeneous networked computers) which is a business enterprise system
  • We consider such an application as a collection of Webservers where we use Web technology to manage business information system.
WebWindows is a multi-client multi-server technology
  • Clients are Mosaic or Netscape browsers

Return on Investment Unclear:
  • Amdahl's law for use of HPCC in Industrial Simulation
    • If Simulation was only 10% or less of original design and manufacturing cycle, then can only gain this 10% by speeding up simulation
    • And this speedup comes at huge software engineering cost !
    • Codes are long and expertise to convert to parallelism may no longer exist in new "slim" companies after layoffs , buyouts and freeze on hiring new employees with knowledge of new technologies such as HPCC
    • New codes must be validated by extensive tests before use
    • Remember we can't solve full Navier-Stokes Equations yet and so some approximations necessary

WebWork is an open, world-wide distributed computing environment based on computationally extended Web Technologies
The backend computation and information infrastructure is provided by the World-Wide Virtual Machine -- a mesh of computationally extended Web Servers (called Compute Servers)
These servers manage (via CGI mechanisms) a collection of standardized computational units called WebWork Modules.
Geographically distributed and Web-published WebWork modules interact by HTTP/MIME based message/object passing and form distributed computing surfaces called Compute-Webs
The front-end user/client interfaces are provided by evolving Web browsers with increasing support for two-way interactivity (e.g. Java, VRML) that facilitates client side control and authoring.
A natural user-level metaphor -- WebFlow -- is supported in terms of visual interactive compute-web authoring tools.

Full HTML Index
Illustrates implementation of WebWork message passing in terms of
  • a): current Web technologies (HTTP/CGI), and
  • b) next generation multithreaded compute-servers
This diagram illustrates point-to-point communication between Web servers, used to implement a webflow channel between compute-web modules. Two extreme implementation modes are described: a) based on today's Web server technology, and b) based on thread memory mapped high performance implementation, expected in future Web compute-servers. Subsequent steps, represented by a sequence of labelled lines in the figure, are described below in both implementation modes.
a) Today's Web server mode: (1) -- M1 locks O1 on S1 disk. (2) -- M1 sends POST HTTP message to S2 with M2 URL in the header sector and with O1 URL in the body sector. (3) -- S2 activates M2 via CGI and passes O1 URL as a command-line argument. (4) -- M2 sends GET method to S1 with O1 URL in the header. (5) -- S1 fetches O1 from its document tree. (6) -- S1 sends the content of O1 to M2 which completes the GET exchange. (7) -- M2 saves O1 by overwriting current I2 on the S2 disk. If I2 is locked, M2 waits (blocks). (8) -- After O1 is saved on the S2 disk, M2 returns 'end-of-transfer' acknowledgment to M1 which completes the POST exchange. (9) -- M1 unlocks O1 and exists.
b) Compute-server (future Web server) mode: (1) - M1 locks its memory object O1. (2) - M1 checks if socket connection to M2 is in M1 connection table. If yes, go to (5) below. Otherwise, M1 connects to S2 and sends M2 creation script. (3) - S2 spawns M2 and acknowledges. (4) - M1 receives acknowledge message and saves new socket in connection table. (5) - M1 gets O1 handle. (6) - M1 writes O1 to M2 using socket lib calls. (7) - M2 reads O1 using socket lib calls. If I2 is free, O1 buffer is copied directly to I2 buffer. If I2 is locked, M2 creates O1 clone and blocks. (8) - M2 sends acknowledge to M1. (9) - M1 unlocks O1 and blocks.

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.
