Features of VPL:
  • Text Editor and File Manager
  • Web Interface for compilation and job submittal with simple aids such as prompts on HPF syntax, choice of platform and automatic makefiles
  • Client side Java applets for Performance and Data visualization
  • Security mechanisms

Can use network of Web Clients and/or Web Servers
Not clear if distinction (in capability) between web server and client will remain
Web Client Models Include SuperWeb from UCSB and hotwired article "Suck your Mips".
More powerful but less pervasive is a pure Web Server model as in NPAC WebFlow
Can either use in controlled (IntraNets or run a server on every node of your MPP) or uncontrolled (the whole world wide web) fashion
  • Uncontrolled mode has interesting economic implications and is controversial in security, network performance area
Note total compute power in all Web "clients" is about 1000 times that in all Central Supercomputers

The layered design includes a secure database at its core on top of which are built a set of services including
  • audio and video servers; basic Web servers and a
  • collaboration subsystem which is heart of both asynchronous and synchronous delivery.
  • This has a set of basic collaboration capabilities including chat, audio-videoconferencing, whiteboard and shared applications.
The communication system supports the worldwide delivery and includes support for distributed databases to get high performance with for instance core courseware replicated on delivery machines with CD-ROM's or other such mechanisms.

The top layer of WebWisdom consists of education and training specific capabilities, which customize and extend the generic middle-layer services.
  • Note assessment relies on database at heart of WebWisdom, which logs synchronous delivery of curricula and records interaction of students with courseware and tools.
  • Authoring and Editing includes audio, video, and Java applet based animations as well as basic text (HTML) material.
    • The latter includes a web presentation system with capabilities similar to PowerPoint and Persuasion but generating directly HTML in a form suitable for presentation.
  • Conversion of Legacy systems includes putting Persuasion Framemaker PowerPoint etc. on the Web.

Full HTML Index
The delivery system is based on customized shared browser windows for curricula together with more generic collaboration capabilities e.g. audio-videoconferencing is used by students and teachers for traditional voice interactions.
  • The collaboration subsystem must support multiple rooms and many groups of users.
We believe that impressive demonstrations of all the above capabilities have already been prototyped and one can now build such a system.
  • Note that as always in the rapidly changing web field it is critical to build systems in as modular fashion as possible and with the loosest (not tightest) relevant coupling.
