Foil 3 Web Software is the Best!

From The National/Next Generation Information Infrastructure in the service of Education Training and Computational Science RCI Federal SIG Meeting Williamsburg Marriot -- April 17 97. *
Full HTML Index
By definition, Web Software will be the "best" software ever built because it has the largest market (and so greatest leverage of investment dollars) and most creative business model (harness the world's best minds together with open interfaces)
  • As Web Software is "distributed computing infrastructure", one will need to customize and integrate for each application
  • Note PC software and perhaps even IBM business OS was high quality software but not so open and not a complete model
One should build upwards from the "democractic Web"
  • e.g. up from POTS --> ISDN/Cable Modem/ADSL --> ...
  • Not down from ..........<--- ATM
This allows you to both deliver your application to the general public (not always required but often desireable) and use the best leveraged software
Note Web Software tends to offer highest functionality as opposed to highest performance and HPCC often requires different trade-offs

Web Technology is still uncertain and there may be major changes but "enough" capabilities are in place to build very general (~all) applications
  • MicroSoft v Sun / Netscape uncertainities
Rapidly evolving Standards and a mechanism to get rapid consensus
Fortran 77 -> Fortran90 --> HPF --> Fortran2000 (23 years)
VRML Idea (1994) --> VRML1 deployed (95) --> VRML2 deployed (early 97) (2.3 years)
  • VRML2 (3D datastructures and Java(Script) enabled methods) is more sophisticated than Fortran ?
  • Java development time was also fast compared to "traditional" standard adoption times

1)Compute Power ? Maybe
2)Network Bandwidth? In some cases
3)Implementing / Discovering new ways of doing Business? Usually the major issue
  • e.g. Can academic Compute Science compete with Industry?
  • Importance of industry implies "we" need a greater focus on "products"
Which organizations will still be here 10 years from now ? Consider University education as an example

Full HTML Index
Many US Universities export education.
Is global communication and "Virtual University Technology" good or bad?
  • There will be access to more students
  • You can teach them "in place". Maybe not so many will come and spend money in US
  • New organizations can compete as don't need so much capital investment to become a Virtual as a Real University!
  • One could get changes in teaching versus residential function of Universities
Many other Enterprises have similar Challenges and Opportunities!

4)Web Technologies are very rich and are perhaps 10 times as complicated as HPCC and Parallel Programming
Much harder to match the drumbeat of web than drumbeat of HPCC
I use a research <--> Teach iterative cycle to learn and understand significance of new technologies
  • I now spend a great deal more time teaching than I used to!
  • The amount of important material appears to require this!
5)Rapid evolution of technologies implies that any "product" is bound to be out of date
  • Use (Web) standards to make it easier to incorporate new standards
  • But VRML2 very different from VRML1
  • JDBC very different from Oracle WoW database technology

Full HTML Index
Problem with HPCC is not ideas but rather finding enough people to implement robust rich software
  • No more people so take software from elsewhere
View parallel computing as a special case of distributed computing with tighter synchronization and lower latency
  • Enhance Web technologies accordingly and use as new HPCC software infrastructure
Java/JavaScript front ends for interoperability and visualization is first step
  • This will link to wrappers around existing Fortran/C++/HPF/MPI code
  • Users will find it convenient to modify this front end as so this is trojan horse which will lead for existing Fortran users converting to Java

Initially Aimed at education where usability higher priority than performance
Teaching Java and JavaScript greatly aided by interpreted technology which allow integration of demonstrations into lectures
VPL aimed at allowing embedding of F90, HPF and MPI (etc.) examples in lectures and convenient support of homeworks for transient inexperienced users.
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

NPAC Web Based Geographical Information System in Stand Alone Mode
A GIS application is a specialized OpenInventor viewer, however it accepts any OpenInventor 2.1 scene model. That's why it's so easy to integrate it with third party applications, which produce IO/VRML output. The images show GIS integration with Weather Simulation application. A GIS viewer can also display animated objects controlled by Simulation Engine.

Full HTML Index
Parallel Java is inevitable and indeed Java will replace Fortran and C++ in general scientific computing
  • We have evaluated what it takes to produce Java interfaces (wrappers) to existing libraries and will deliver this on compiler runtime (see Java-MPI at our Web Site)
The (commercial) Web itself will lead to "coarse grain software integration" in AVS like data flow environments
  • This will implement metacomputing with a rather different model than before
  • Link mobile Web modules rather than decomposing problems
Web Collaboration technology can revolutionize computational steering
  • Java Servers will link Instruments, People, Computers

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

Clearly Java Collaboration Systems are natural implementations of general environments that mix computers and people
Computational Steering -- a simulation is like a participant in a Tango session which has
  • simulation engine
  • visualization subsystem
  • one of more computaional scientists
Need to link to Tango, Java data analysis/visulaization front ends as well as distributed resource management systems such as ARMS from Cornell

Note synergy with Java Server based distributed computing such as WebFlow which builds an AVS like environment with graphical interfaces to software Integration
More ambitious to upgrade discrete event simulation component of TANGOsim to support full SIMNET/DSI (Distributed Simulation Internet) functionality.
Note that Java is natural language for DSI/Forces Modelling because these typically use object parallelism which fits both language and applet/JavaBean capabilities.

Java is currently semi-interpreted and (as in Linpack online benchmark) is about 50 times slower than good C or Fortran
  • http://www.netlib.org/benchmark/linpackjava/
Java --> (javac)--> Downloadable Universal Bytecodes --> (Java Interpreter)
--> Native Machine Code
  • Just in Time Compilers speed this up by factor of 10
However Language can be efficiently compiled with "native compilers"
Java ----> (native compiler)
---> Native (for Particular Machine) Code
Lots of Interesting Compiler issues for both compiled and scripted Java

Foil 30 What Limits Performance of Compiled Java?

From The National/Next Generation Information Infrastructure in the service of Education Training and Computational Science RCI Federal SIG Meeting Williamsburg Marriot -- April 17 97. *
Full HTML Index
Syracuse Workshop saw no serious problem to High Performance Java on sequential or Shared Memory Machines
Some restrictions are needed in programming model
For instance, Avoid Complicated Exception handlers in areas compilers need to optimize!
Should be able to get comparable performance on compiled Java C and Fortran starting with either Java Language or JavaVM bytecodes
The Interpreted (Applet) JavaVM mode would always be slower than compiled Java/C/Fortran -- perhaps by a factor of two with best technology

Applications requires a range of capabilities in any language
High level ("Problem Solving Environment") manipulating"large" objects
  • Semi Interpreted (Java Applet) or Interpreted (Improved JavaScript)
Intermediate level Compiled Code targetted at "sequential" (multi-threaded) architecture
  • Existing Native Compiled Java using Simple types (arrays) for numerically intensive parts
  • Note as no pointers and no overloading of basic operators, Java code should be very efficient
Lower level runtime exploiting parallelism and memory hierarchies
  • "Hints" from higher level languages (in HPF style?) referencing highly functional efficient runtime optimized for high performance architectures
  • Requires extensions to both message passing and data parallel interfaces for whatever language one uses

1)Classic solution of large scale PDE or Particle dynamics problem
  • Data parallelism over grid points or particles
2)Modest Grain size Functional Parallelism as seen in overlap of communication and computation in a node process of a parallel implementation.
  • More generally overlap of I/O -- disk,visualization -- and computation
3)Object parallelism seen in Distributed Simulation where "world" modelled (typically by event driven simulation) as set of interacting macroscopic (larger than grid points) objects
  • Objects are weopens, military units etc. in SIMNET/DSI (Forces Modelling)
4)MetaProblems consisting of several large grain functionally distinct components such as
  • Structural Analysis, Airflow, Manufacturing Process, Pricing, Controls etc. in MDO approach to manufacturing and design
  • more generally are components of a Problem Solving Environment
Java: 1) Not Supported, 2) is Thread mechanism, 3) is Java Objects or Applets, 4) is JavaBeans or equivalent
Fortran: 1)is supported in HPF, 2--4) are not supported

Foil 34 Some Critical Features of Java and Parallelism - II

From The National/Next Generation Information Infrastructure in the service of Education Training and Computational Science RCI Federal SIG Meeting Williamsburg Marriot -- April 17 97. *
Full HTML Index
As we saw large scale Applications need many forms of parallelism and it is not needed/appropriate to use the same mechanism for each form
  • Coarse Grain Software Integration or Coordination (item 4))
    • Naturally built into Java through Applet mechanism and networking classes
  • But Data Parallelism (item 1)) -- needed for "massive parallelism" -- but although not directly supported, we can do by hand!
Thus Java needs (runtime and perhaps language) extension to support HPF/HPC++ like (shared memory model for programmer) data parallelism but "Java plus message passing" is already here
  • Most Examples of Java+MP are in Information arena (This is how you build Java Collaboratories) but scientific examples are emerging
  • We can do Java+MP for "Laplace Equation Jacobi Iteration" and this how we (Caltech) started hypercube work in 1981
  • Note that Fortran or C plus message passing (PVM,MPI) is dominant implementation technology for data parallelism over last ten years

Java raises issue of role of Interpreters versus Compilers
Success of systems like MATLAB and languages like APL show relevance of interpreters in Scientic Computing
PERL, JavaScript, TcL, Visual Basic etc. indicate growing use of Interpreters in other domain
  • Natural as computers get faster!
We suggest that integration of Interpreters and compilers is an important research issue and could suggest new models for parallelism
  • We need both Compilers and Interpreters!!
Optimizing Interpreters (as in JIT for Java)
A library model where interpreted toolkits invoke lovingly parallelized high performance libraries
Natural linkage to interpreted data analysis / visualization

Take Web electronic society technology which link people together and use to join teachers mentors and students
  • Whereas HPCC needs "upscale" collaboration technology, education should be designed so that one can link to peoples' homes and so use democratic technology
Meanwhile can look at VRML2 for Immersive virtual learning environments
All of these technologies can be used either synchronously (organized sessions) or asynchronously (students learn in their own time and interact with teacher/mentor in batch mode)
Log educational sessions (including multimedia material) in databases and use for assesment

  • should integrate with HTML editor to allow student annotation
Currently WebWisdom used in non TANGO mode with classic large screen display
TANGO WebWisdom allows one to use same approach to distributed PC's which is surely more attractive (Web font sizes designed for monitors -- not classroom displays)

Foil 48 Distributed Tango WebWisdom

From The National/Next Generation Information Infrastructure in the service of Education Training and Computational Science RCI Federal SIG Meeting Williamsburg Marriot -- April 17 97. *
Full HTML Index
To allow use on low speed lines (28.8 kbaud modems), distribute CD ROM of material to students
Client WebWisdom will map URL sent from Teacher WebWisdom to link on PC (if exists) and so ONLY control information is sent on Web
Standard low bit rate codecs support audio and video conferencing over phone lines
For asynchronous learning, ship HTML Index with lesson audio to clients and students use offline with TANGO used to support synchronous audio and video conferencing
Will use in China (already succesfully used material Spring 96 Semester between Syracuse and Harbin) and for Syracuse University "Limited Residency" continuing programs where students visit University once to three times per semester (see Computing for the Future Certificates)
  • Corporate Programs where we substitute limited residency at Syracuse by University team visiting site where many students can congregate

Foil 50 Opportunities in Education - Applications

From The National/Next Generation Information Infrastructure in the service of Education Training and Computational Science RCI Federal SIG Meeting Williamsburg Marriot -- April 17 97. *
Full HTML Index
Initial applications include corporate training and University continuing education
  • Students more motivated than at lower levels K-12-Undergraduate?
This is outreach to people wanting to learn new skills and so critical as all organizations redefine themselves
Also use in Chinese Universities and HBCU's in the U.S. where we can help faculty upgrade their curricula
NPAC will have all these capabilities in a deployable system by end of 97.
