Full HTML Index
Most of the real world WebTop Systems will involve multi-user collaboratory modules. Even for scientific computing, complex toolkits such as WebAMR will be most conveniently supported by interactive consultation between developers and users.
Collaboratory multi-user components will be further enhanced in enterprise, commerce and community systems.
This is illustrated in our recent telemedicine prototype for nursing triage. Here we start from the collaboratory component involving nurses, nurse practioners and pediatricians and add HPCC components such as medical imaging and agent based diagnosis.
We view the Bridge topology (Warner & Balch '95), underlying such telemedicine systems, as a promising generic framework, applicable also for other problem domains.
A generic bridge includes "points of need", "points of expertise" and intelligent middleware that manages information resources and provides connectivity between customers and optimal services.

Foil 12 General Framework of WebMed - Telemedicine Lessons

From Web Application and Services Overview as of June96 NASA ICASE Tutorial -- June 10-13 1996. * See also color IMAGE
Full HTML Index
Telemedicine concepts until mid '95 were based on the assumption of rapid onset of the broadband wide area networking infrastructure.
Dominant anticipated medium was direct life video linkage between patients and physicians.
However this is not considered by some to be very succesful and new approach to Telemedicine is based on decision support for doctors with an environment very similar to that needed by Command and Control in the military or the LOTUSNotes like environment in Business
  • Need Image Processing in medicine not weather simulation as in military or market segmentation analysis in Business but similar adaptive access to diverse distributed databases
Slowdown in the ATM deployment, rapid explosion of Web technologies with variable bandwidth conditions, and new social and economic needs for the managed care based medicine, implies currently the paradign shift in the near term telemedicial environments.

Warner' team came up with the Bridge Concept which was prototyped by his organization I3 and ECU and succesfully demonstrated with Web Components from NPAC at WWVR'96 in San Diego
The Bridge connects patients/care portals with quality healthcare professionals (DOCking stations) via the intelligent middleware station(this will be Web), offering suitable routing and optimizing the message traffic, service quality and expert time utilization.
The emerging Web based framework (WebMed) addresses near term implementation in terms of today's networks and matches the social/patients and HMO/economy needs in terms of pervasive low cost infrastructure.
New Web based telemedicine initiative WebMed at NPAC addresses these issues in a set of planned pilot projects.

  • 1) nurse terminals in schools, connected to
  • 2) nurse practitioner station at the SU Nursing College, connected to
  • 3) pediatrician station at SUNY HSC.
This is a Pilot project to prototype an instance of the telemedicine Bridge concept.
Home care terminals - Our initial project is a Web (Java/JavaScript) version of Warner's "neat thing" sensory front-end, with rehabilitation and disabilities as initial application target.
  • This builds on Warner's earlier activity in VR for which he is well known
This allows Doctors to interact with Patients at the Home with Instruments monitoring their health
  • In "neat thing" we also build a device to allow the disabled to access the Web as we can replace Mouse/Key board input with any measurable human signal

We are experimenting with home care terminals based on David Warner's "neat thing" sensory front-end, with rehabilitation and disabilities as initial application target.
  • We have rewritten original PC code in Java to allow Web Integration of sensory input and output
This allows Doctors to interact with Patients at the Home with Instruments monitoring their health
But it also allows Disabled access to Web and to Education on the Web as "neat thing" allow us to replace Mouse/Key board input with any measurable human signal
For structured data at least, we have full control over both Patient and User Interface.
  • If not enough "resolution" to move mouse, can replace clickable URL's by scrolled list in Java or JavaScript with clickable NEXT PREVIOUS GO or SKIP-10 URL's in list etc discrete buttons controlled by disabled

Channels are calibrated to select "windows" of their ranges of signal amplitude. The green and red lines, which are set by mouse dragging and clicking, set the lower and upper limits of the range of interest. When a signal is within range, the button turns from blue to green, and this condition can correspondingly control a binary output device.

  • U.S.A.. to first offramps: Coastal Countries (in Africa)
  • Coastal Countries distribute information in cascade fashion to rest of continent
  • Download bulk educational material ONCE (standard caching scenario)
  • Use FLAG Interactively for exploration and for student-teacher Interaction

We suggest that Universities historically are "approved" to give "licenses" i.e. certification that students have a certain level of knowledge
In the emerging Web based Virtual University, the traditional type and length of learening cycles is not obviously appropriate
Further we need to bootstrap WebWisdom and "suck customers in" a little bit at a time!
Thus suggest Scalable Certificates
  • Level 1: One day (6 hours)
  • Level 2: One Week (30 hours)
  • Level 3: One Semester/Quarter Course (120 hours)
  • Level 4: Minor/Certificate -- about 5 courses (600 hours)
  • Level 5: Masters degree -- about 12 courses (1400 hours)
Note these certificates are also portable as can take anywhere at any time!
Traditionally, University courses are 1/3 interaction and 2/3 study/homework
  • i.e. 120 hour course is 40 hours lectruring

I expect Java to be the the dominant implementation language for everything on the Web from Servers, Clients, MOO's, filters, Animations, Simulations etc.
Can build neat clickable images including Visible Human (biology education!) and our 2D "Interactive Journey" clickable GIS for New York State
This has several obvious near term applications including some examples of education in HPCC arena:
  • Downloading software for demonstrations or general client side computing
  • Use of Java to animate the display of performance visualization data
  • Use of Java to produce visualizations of data movement in algorithms such as matrix and particle dynamics -- Brown University initially demonstrated in sorting
The above examples are quite interesting reasons for introduction of electronic journals as you should be able to explain complex ideas better this way
Note Web was initially book/libraries done digitally.

  • Experts can add insight as to why things are what they are!
VRML is Very good GIS (Geographical Information System) technology and can be used by NASA/EPA etc for presentation of spatial data with again clickable annotations

Can also store unstructured information as illustrated by Usenet computer and other relevant newsgroups
Use the powerful Search engines with domain (i.e. particular courses) specific keywords . These can be attached to commercial (e.,g. altavista) or inhouse Web Search sites so search confined to subset of curricula material

Digital Audio and Video is currently less than 5% of web data but eventually it will be dominant (95%) form of digital information and serving will be major Web activity.

The trip to the opera was the high point for the thousands of international visitors to the conference.
They were streaming out of the new center which had been built in a decaying downtown area. Here old warehouses were still mixed with the proud new buildings of the economic redevelopment zone.
Luke CyberCzar was in charge of the crisis center when the first 911 video dial tones showed the horrifying sight. A gigantic set of explosions rocked a set of old chemical warehouses and fires and fumes of unknown composition ringed the new opera complex. The frightened audience panicked and scattered this way and that into the surrounding alleys. Of course the digital video crews covering the opera immediately switched their cameras to this catastrophe. Just a few seconds after those 911 calls, all the MPEG decoders on the GII were presenting the chaos, damage and injuries live to a world whose cybereyes were trained on Luke.

Luke benefits from the natural convenient interface maximizing the effectiveness of the tired harried judgment maker. This build on advanced MOO and VR ideas and tailors the computer interface to the problem at hand.
Luke sees a three dimensional GIS (Geographical Information System) when viewing the spatial confusion of the catastrophe; a virtual podium when he briefs cyberworld; a boardroom when defending his actions to angry foreign politicians; a summer wildflower meadow in moments of thought.
He shares this virtual environment with Jane who is in charge of tactical operations for the crisis and by his electronic side at all times.
They share this televirtual environment with other judgment makers and those facing the crisis in the field.
Whether supported by supercomputer or hand held personal assistant, all access the same WebTop environment with a full range of collaboration and productivity tools whose capability adjusts to the available compute and communication resource.
In this way the GII enables the best adaptive linking of "come-as-you-are" computational, communication and personnel resources.

Foil 153 Path Integral Approach to Derivative Valuation

From Web Application and Services Overview as of June96 NASA ICASE Tutorial -- June 10-13 1996. * See also color IMAGE
Full HTML Index
We developed new algorithms for risk neutral valuation of derivative financial instruments
Theoretical prices of derivative instruments are obtained by discounting their expected payoffs under the equivalent martingale measure using money market interest rate.
The core algorithm is Path Integral Monte Carlo which used to generate arbitrary distributions of underlying risk factors (stocks, bonds, short interest rates, commodities, indices etc.)
The advantage of the new algorithm is that sensitivities of derivative prices with respect to changes in all model parameters are computed in a single simulation.
  • This is crucial for effective hedging.
Parallel version of the algorithm is written in C and MPI and relies on task parallelism and functional decomposition (could also use HPF)
Monte Carlo samples are generated on multiple processors in embarrassingly parallel fashion

Full HTML Index
Pricing modules can either run in lock-step with the Monte Carlo module which generates histories of risk factors or asynchronously perform valuation functions on the histories which are broadcast as they are generated by the Monte Carlo module
We are linking this flexible algorithm with a novel scheme based on Maximum Entropy method which generates implied probability distributions from reported option prices.
The implied distributions can be used within the Path Integral Monte Carlo module to price exotic contracts consistently with exchange-traded contracts and they can also be used to search for arbitrage opportunities
Estimation of implied distributions requires large scale global optimizers.
We are developing two parallel stochastic optimizers based on mean field approximation (Laplace formula) and Langevin equation

  • display charts and histograms of historical data
  • estimate parameters of the underlying stochastic processes
  • enter own estimates of model parameters

The WWVM is accessed through a Web Browser and requests are sent to the server through HTTP Protocol.
HTTP Server starts a service master which translates given HPF program to F90 with message passing calls and starts-up other client servers.
HTTP Servers at the client side get the requests through the HTTP protocol connection, and activates a Interpreter CGI module.
Interpreter makes calls to the Runtime Support and Communication Server that sends and receives messages using PVM daemons.

Foil 191 Web Technologies at NPAC: WebAMR Example

From Web Application and Services Overview as of June96 NASA ICASE Tutorial -- June 10-13 1996. * See also color IMAGE
Full HTML Index
We illustrate here how the individual component technologies cooperate in a complete application, WebAMR (Adaptive Mesh Refinement)
A mesh of computationally extended Web servers, connected via HTTP based message passing, acts as WebVM that runs PDE solver modules for individual grids
In a simple static AMR topology (WebWork model), a tree of refined meshes is constructed by the user via the AVS like visual programming tools (WebFlow)
Dynamic AMR trees require interpreted programming support -- a pilot "little language" design towards WebHPL
WebAMR applications can be configured and run on heterogeneous clusters, including any WebWindows compliant platform
Example of WebTop System in this domain in a set of WebVM/WebFlow modules, packaged and customized as a PDE Toolkit for a given Grand Challenge community.

Foil 192 Interpreters versus Compilers -- I?

From Web Application and Services Overview as of June96 NASA ICASE Tutorial -- June 10-13 1996. * See also color IMAGE
Full HTML Index
We need to use compilers on tightly coupled systems such as MPP's (shared and distributed memory)
But for metacomputing, the hardware intrinsically has latencies that suggests increased flexibility of interpreters is more appropriate
  • This implies a hybrid compiler-interpreter environment
Maybe frontends should be built with interpreters such as object-oriented PERL5 so easier to link with Web.
Note that interpreted environment will have best software engineering support and so suggestion is -- taking SP2 as example:
  • debug on SP2 set up with compute-enhanced Web Server on each node with say MPI running on top of HTTP message passing protocol
  • execute debugged code on conventional SP2 with high performance compiled environment

Foil 193 Interpreters versus Compilers -- Domain Specific Environments

This implies that we should allow hybrid model not just for task (interpreted) versus data parallelism(compiled)
  • Rather should support full data parallelism in interpreter
  • NPAC demonstrated a protype HPF interprter at SC93
Current Web Interpreters include Java TCL and PERL(5) which are optimized for different application domains
  • For instance PERL is optimized for documents/files and Java for browsers
This leads to WebScript Concept of interoperable interpreters optimized for different domains
  • WebHPL (High Performance Language) is then script optimized for computing which links compiled HPL modules on tightly coupled MPP's
  • This naturally suggests that we can link domain specific systems (e.g. partial differential equation toolkit) to HPF future and WebHPL

Foil 194 Java and HPF Futures

From Web Application and Services Overview as of June96 NASA ICASE Tutorial -- June 10-13 1996. * See also color IMAGE
Full HTML Index
Java is a C++ subset which interestingly does not have pointers as these are unsafe in necessary secure metacomputing environment.
Thus Java has removed the part of C++ which is hardest to parallelize
Java may not "survive" but if it doesnt something better will! Thus it makes sense to study and experiment with it
Natural first step is to use Java to build the interpreted "shell" which we called HPFCL for HPF coordination Language.
  • This is task parallel script linking HPF modules
Java is partially compiled as you take basic Java high-level code and compile down to a universal Java machine language. This is very similar to concepts in ANDF (Architecture Neutral Distribution Format) but with a different goal
  • Java's model supports universal heterogenous clients linked together in metacomputing

Foil 195 VRML and HPF Futures

From Web Application and Services Overview as of June96 NASA ICASE Tutorial -- June 10-13 1996. * See also color IMAGE
Full HTML Index
VRML -- Virtual Reality Model Language -- is an object oriented database built as a subset of the SGI Inventor System
VRML can be considered as another script optimized for graphics but not many interesting processing (compute) capabilities are in current standard
VRML can be considered as an example of a universal data structure allowing exchange of 3D objects over the Web.
  • These objects could either be tanks in a videogame or parts of an aircraft used in large scale simulation
Thus useful to consider data parallel VRML and building CC++ or HPF(Fortran90) modules to support VRML
HPCC community should join with the Web to ensure that standards such as VRML can be implemented efficiently either in parallel (maybe a niche) but also in a distributed network (similar issues where HPCC can contribute and clearly very important)

Foil 196 Some Remarks on HPJava

Features of the Java language and runtime
  • Secure, architecture neutral, Object Oriented but simpler than C++
  • runtime modules dynamically downloadable with applet mechanism and portable opcodes (from PC, Mac, to Workstation)
Can build on existing work on HPF HPC++ -- especially latter
Two basic types of opportunities:
  • Build a modest performance totally portable runtime in Java
  • Use current PCRC runtime as native classes for a (data-parallel) Java
  • What is minimum set of PCRC routines which MUST be native(C)?
Applet mechanism naturally incorporates task parallelism -- need to add "channel" class (as in Fortran-M, CC++) to augment "thread" and "socket" classes
  • Need to implement Java runtime in Nexus or similar distributed thread package -- again native Java would be portable but lowish performance
Java can be used both on Server and Client side as expect soon good Java based clients and servers
