GLOBAL foilset Overview foils for NII Review for MADIC

Given by Geoffrey C. Fox at NASA/MADIC Workshop on NII Requirements for ASOP on May 22-23 1995 Arlington TX. Foils prepared May 25,1995
Abstract * Foil Index for this file See also color IMAGE

This overview was part of a NASA sponsored workshop involving MADIC (Multidisciplinary Analysis and Design Industrial Consortium) Team 2, NASA, Georgia Tech, Rice and NPAC.
This started a MADIC activity to identify and demonstrate the use of NII technology in ASOP (Affordable Systems Optimization Process) -- a novel approach to Multidisciplinary Optimization for aircraft and other complex system design.
ASOP intrinsically involves world wide collaboration between several large aerospace corporations and tens of thousands of suppliers and so the NII can have major value both for supporting collaboration between people and for supporting the thousands of linked optimizations -- each involving several different programs.
We stress the rapid evolution of the Web and the ability of Web Technology to be applied to Enterprise Inforemation Systems such as that required to manage ASOP.
MADIC companies involved include Rockwell, General Motors, McDonnell Douglas, Northrop-Grumman-Vought, Lockheed-Martin and General Electric.

High Performance (Parallel) Computers on High Speed (ATM) Networks linked to clients at a network performance that supporting realtime Video at a resolution between VHS,HDTV .
MPP's as Internet/Web/NII/GII Servers
  • NII/GII= National/Global Information Infrastructure
  • Supports Decisions by everybody in society
  • Consumers, Healthcare, Teachers, Schoolchildren, Business, Military,
Dual-Use Philosophy must be extended to Multi-Use
  • Different applications must share services
Standards must be used
  • from HPF/HPC++ in simulation arena to
  • to TCP/IP on ATM in networking
  • to parallel relational databases
  • to "Web" technology for multimedia

One must provide real time video to some 100 million NII off ramps and there are many choices such as:
Optical Fibre Trunk System (ATM)
  • This seems Certain
Satellites for Trunk System
Local Cable Delivery (Optical --> Cable Switch) - several megabits/sec
  • Certain in populated areas
ISDN (0.1 megabits/sec) down twisted pair
ADLS (several megabits/sec) down twisted pair
Full Optical Fibre Link
Mobile Computing

"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
  • consumer products drives better high end business and research user level products e.g., cheap Virtual Reality Interfaces
  • MPP's are information servers for consumers, business, research

InfoVision is ultimate "client-server" application
  • 108 clients -- each of which could be (small) servers -- in fact Web Technology will migrate to democratic "server-server" architecture
  • 104 large (~$10M) parallel servers -- each of which could have 1000 to 10000 nodes
Democracy on the NII (Gore)
  • Everybody can access information on the NII
  • Everybody has equal opportunity to put information on the NII

The different application areas such as business, defence, government, education and healthcare can leverage off the infrastructure and services motivated by home use.
Clearly each areas needs somewhat different functionality and trade-offs in services

WebMagic -- HTML editor which essentially integrates server and Netscape client on a single computer for fast client stand-alone editing.
VRML which is a 3D data structure which could be used in display of ASOP physical artifacts. It is based on open subset of SGI Inventor database technology. VRML viewers are just coming out
JAVA has just been released by a group in Sun and in some ways competes with VRML (viewers). It is a Client technology which includes a C++ subset interpreter allowing clients to spawn processes called Applets. This makes clients "intelligent" and largely indistinguishable in functionality with servers.
Note future Web Architecture will be Server-Server. Not Client-Server.

Full HTML Index
A Set of Application domains and each with its own natural (interpreted) language manipulating domain-specific data structures. WebScript links the domains together
Examples are:
  • PERL for world of Text (PERL includes C(++), UNIX shell and text processing Awk and Sed capabilities)
  • JAVA for constructing browsers
  • VRML is data structure for 3D objects which are viewed by VRML viewers
  • WebHPF is Interpreted distributed High Performance Fortran used in CFD simulation, structures etc. (for ASOP)
  • Web AVS is Web implementation of AVS(Khoros) and can be used for coarse grain software integration
  • WebASOP is designed to translate between different disciplines (uses some version of PDES/STEP product specification data structures) and link all the 10,000 different programs/expert systems etcx.
