Scripted foilset Distributed Systems on the Pragmatic Object Web -- Computing with Java and CORBA

Given by Geoffrey C. Fox at Computational Aerosciences in the 21st Century Hampton VA on April 23 98. Foils prepared 21 April 98
Outside Index Summary of Material

We review emerging approaches to HPCC for both tightly coupled parallel hardware and computational grids -- geographically distributed metacomputers.
We base the discussion on the growing power and capability of commodity computing and communication technologies largely driven by commercial distributed information systems. These systems are built from CORBA, Microsoft's COM, Javabeans, and less sophisticated web server and networked approaches.
One can abstract these to a three-tier model with largely independent clients connected to a distributed network of servers. The latter host various services including object and relational databases and of course parallel and sequential computing.
This network of servers encompassing disparate object and web standards is termed the "Pragmatic Object Web" and we show how to use these concepts even when there is no one universal standard.
We look at the implications for educational curricula in "non computer science technical fields"

Full HTML Index
HPCC has developed good research ideas but cannot implement them as solving computing's hardest problem with 1 percent of the funding
  • HPCC applications are very complex and use essentially all computer capabilities and also have synchronization and performance constraints from HPCC
We have learnt to use commodity hardware either
  • partially as in Origin 2000/SP2 with consumer CPU's but custom network or
  • fully as in PC cluster with fast ethernet/ATM
Let us do the same with software and design systems with maximum possible commodity software basis

Foil 5 What is Commodity Software

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
The world is building a wonderful distributed computing (information processing) environment using Web (dissemination) and distributed object (CORBA COM) technologies
This includes Java, Web-linked databases and the essential standards such as HTML(documents), VRML(3D objects), JDBC (Java database connectivity).
  • The standard interfaces are essential in that they allow modular (component based) software
We will "just" add high performance to this commodity distributed infrastructure
  • Respecting architecture of the object web, should allow us to naturally use improved software as it produced
The alternative strategy starts with HPCC technologies (such as MPI,HPF) and adds links to commodity world. This approach does not easily track evolution of commodity systems and so has large maintenance costs

Foil 6 Pragmatic Object Web Technology Model - I

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
Basic Vision: The current incoherent but highly creative Web will merge with distributed object technology in a multi-tier client-server-service architecture with Java based combined Web-ORB's
COM(Microsoft) and CORBA(world) are competing cross platform and language object technologies
  • Javabeans plus RMI is 100% pure Java distributed object technology
  • Every Netscape4 browser has a Visigenic ORB built in
  • W3C says you should use XML
Need to abstract entities (Web Pages, database entries, simulations) and services as objects with methods(interfaces)
  • CORBA is "just" CGI done right
How do we do this while infrastructure still being designed!
Major Commercial Java Activity today is on Server NOT Client

One can anticipate this by building systems in terms of Java objects e.g. develop Web-based databases with Java objects using standard JDBC (Java Database Connectivity) interfaces
  • Oracle DB2 Informix Sybase, Lotus Notes, Object database confusion becomes an issue of performance/robustness NOT functionality
  • Use CORBA to wrap existing applications
Even better use (Enterprise) Javabeans which are Java's (middle tier) or client componentware offering visual interfaces, containers (here they are consistent with CORBA standard) and standard software engineering interfacing rules
  • e.g. Java Blend is built on top of JDBC to use enterprise Javabeans to store Java Objects in relational databases

Foil 8 Exploiting Multi-Tier Commodity Software Model

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
Essential idea is consider a three tier model
  • Top tier is the client (in "Network Computer" based 4 tier architectures this becomes 2 tiers)
  • Second tier are servers coordinated by commodity technologies such as the Web and CORBA and communicating via HTTP(Web), IIOP(CORBA), RMI or custom Java sockets.
  • Use middle tier component/container model -- Enterprise Javabeans
  • Third tier are services such as databases, MPP's
Preserve the first two tiers as a high functionality commodity information processing system and confine HPCC to the third (lowest) tier.
  • MPI becomes the high performance "machine code" for message passing which you use if HTTP, IIOP or RMI have insufficient performance

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
HPcc is High Performance commodity computing
Encapsulate services (from databases to instruments to MPP's) as middle tier distributed objects using an approach that will evolve to COM/CORBA in future but is deployable today
  • JDBC (Java Database Connectivity) links to databases
  • (Java) web server/CORBA JWORB interfaces to compute modules
  • Client Side Javabean visual interfaces
  • Server Side Enterprise Javabeans
Establish Java Frameworks and Equivalent CORBA Facilities
  • for Computing Services
  • Distributed Scientific Objects DSO -- Compute and Data sectors --- with several domain specific interfaces inherited from DSO
This already gives you an approach to seamless access and a framework for composing complex metaproblems by linking programs together or programs to databases

Foil 16 Three Roles of Object Web Technologies in Computing

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
1)One can "just" use Object Web technologies as a software infrastructure for building parallel, distributed or sequential computing environments which can have a very different architecture from the Web
  • e.g. write software in Java
  • e.g. adopt interfaces/standards such as JDBC, VRML, Java3D
2)Harness the power of the Web as a computer -- use up the idle cycles on the WebTV's in every home -- typically a Web Client based system
  • We will not discuss this here
3)One can view the Object Web as a distributed information system with modest performance and build a metacomputing system with the Web architecture
  • we "only" need to enhance the Object Web to get high performance
  • several ways of doing this -- common feature is that they all inherit rich web capabilities -- typically Web or Object Server based
  • By inheriting Object Web architecture, naturally track evolving and improving commodity technology base

Larry Smarr and NCSA Collaboration have stressed analogy of deployment of computer/communication technology with impact that electrical and transportation grids had
  • I.e. they enabled revolutions in society
  • What is relative role of High-end and Commodity-end in Grid?
The transportation system was built using lessons from and feed up/down from Sports cars, Cadillacs, Model T's, Ford Escorts etc.
Computational Grid will be shaped by and shape all applications and technologies
Internetics expresses synergy between high-end and commodity approaches
A computational grid is a metacomputer or a "high performance distributed computer system" which must be influenced by and influence the "Object Web" which is here defined as "mass-market"/business IntraNet (low to low) use of Internet/distributed Information Systems

Foil 18 Structure(Architecture) of Applications - I

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
Applications are metaproblems with a mix of module and data parallelism
Modules are decomposed into parts (data parallelism) and composed hierarchically into full applications.They can be the
  • "10,000" separate programs (e.g. structures,CFD ..) used in design of aircraft
  • the various filters used in Khoros based image processing system
  • the ocean-atmosphere components in integrated climate simulation
  • The data-base or file system access of a data-intensive application
  • the objects in a distributed Forces Modeling Event Driven Simulation

Foil 19 Structure(Architecture) of Applications - II

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
Modules are "natural" message-parallel components of problem and tend to have less stringent latency and bandwidth requirements than those needed to link data-parallel components
  • modules are what HPF needs task parallelism for
  • Often modules are naturally distributed whereas parts of data parallel decomposition may need to be kept on tightly coupled MPP
Assume that primary goal of metacomputing system is to add to existing parallel computing environments, a higher level supporting module parallelism
  • Now if one takes a large CFD problem and divides into a few components, those "coarse grain data-parallel components" can be supported by computational grid technology
  • so no clean division but coarse grain modules are general goal!

Foil 20 Metacomputing with Web Architecture

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
It is natural to base on either a network of Web Clients or Web Servers
  • Not clear if distinction (in capability) between web servers and clients will remain as clients are adding functionality and any PC can run a server as well as a client!
Web Client Models Include SuperWeb (Javelin) from UCSB and are well illustrated by the January 1997 hotwired article "Suck your Mips".
Greater functionality but less power and pervasiveness is a pure Web Server model as proposed by NPAC
  • Can either use in controlled (IntraNets or run a server on every node of your MPP) or uncontrolled (all the world wide web hosts) fashion
  • Uncontrolled mode has interesting economic implications and is "controversial" for security and network performance area
Note total compute power in all Web "clients" is about 100 times that in all Central Supercomputers

Foil 21 One Strategy for a Object Web-based Metacomputing

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
Object Web Software provides a high functionality but modest performance distributed computing (Metacomputing) environment based on either Web (soon to be CORBA IIOP and HTTP/Java Socket) Servers or Clients
Here we will explore an architecture using servers for control as higher functionality than clients although currently less broadly deployed
  • Some "parallel" computing problems (e.g. embarrassingly parallel ones) can "immediately" use Web as a parallel engine with no performance enhancements
Object Web Only addresses Integration of already decomposed parts!
  • Inherit and extend decomposition (data-parallel) technology from HPCC (parallel compiler and library technology)
  • Compose / Integrate Modules with Web Technology
  • Inherit all the pervasive (not high performance) services from the Web

Full HTML Index
HPcc can be applied to either parallel or high-performance distributed computing (aka metacomputing)
In metacomputing, HPcc fills a void as few if any high level tools
In parallel computing, HPcc provides uniform and perhaps more attractive sustainable user environment
Can view a parallel computer either as a single tier 2 object
  • or as a collection of tier 2 objects -- one per node
Both are interesting
  • As a single object provides a CORBA like facility of invoking as a distributed object
  • As one object per node, can use HPcc to provide node level programming environment

The "Host" is logically a separate Corba object but could of course be instantiated on the same computer as one or more of the nodes. Using the protocol bridge of fig. 15, one could address objects using Corba with local parallel computing nodes invoking MPI and remote accesses using Corba where its functionality (access to very many services) is valuable.

Full HTML Index
YES! If one uses the same separation between control and data transfer explained for metacomputing case
Build a "bridge" that accepts MPI HTTP or CORBA invocation but invokes either the powerful slow CORBA mechanism or the nifty optimized MPI
Why address nodes as CORBA? -- so you can build applications uniformly so they can access nodes and servers around the world in same message passing style
Why address nodes with MPI? -- so you can get code that executes very fast!
Why address nodes with HTTP? -- so you can get advantages of CORBA today as Web Servers dominate!

NPAC has built JWORB which is a Java server which supports both the Web and CORBA(distributed object) protocols
  • JWORB supports RTI and so allow one to build Web Tools for FMS/IMT DoD (DMSO) communities (RTI is event driven simulation equivalent of MPI)
  • WebFlow will become an HLA Programming Environment
  • JWORB could support MPI and so link HPCC and DMSO
Commercial systems can bridge COM and CORBA

DoD modeling and simulation (FMS,IMT) community is currently evolving towards the HLA(High level Architecture) framework with the RTI (Run Time Infrastructure) based communication bus.
The goal of HLA/RTI is to enhance interoperability across more diverse simulators than in the DIS realm, ranging from real-time to time-stepped to event-driven paradigms.
HLA defines a set of rules governing how simulators (federates) interact with each others. Federates describe their objects via Object Model Template (OMT) and agree on a common Federation Object Model (FOM).
The overall HLA/RTI model is strongly influenced by the CORBA architecture and in fact the current prototype development is indeed CORBA based.
Building HPCC on the Object Web implies that we can a common framework for both distributed (event driven) simulations and classic time stepped parallel computing

Currently WebFlow uses a Java Server and manipulates Java applications which can be frontends with native methods to Fortran C or C++ routines
Change Java Server to JWORB -- server integrating HTTP and IIOP (Web and CORBA)

They are Java's implementation of "component-based" visual programming
This modern software engineering technique produces a new approach to libraries which become a "software component infrastructure(SCI)"
There is a visual interface to discovery of and setting of values of and information about parameters used in a particular software component
JavaBeans uses the event model of JDK1.1 to communicate between components
  • This is exactly the ideas we used to get high performance separating control and data transfer
One expects Javabeans to become the CORBA component interface (defining containers in CORBA)

The visual interface allows inspection of and implementation of both individual beans and their linkage . This visual construction of linkage allows one to form nontrivial programs with multiple communicating components
  • We will see this as next step for WebFlow
Apart from the event mechanism which is a communication/linkage mechanism, ComponentWare (and JavaBeans in particular) "just" give a set of universal rules (needed for interoperability) for rather uncontroversial (albeit good) object-oriented and visual programming practices
  • Hiding of properties which can only be accessed by methods (which must have special names)
  • Display of these properties (as given by methods)

Foil 45 Wrapping Existing Applications -I

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *

CORBA is natural distributed object formalism
Java (with visual interfaces i.e. JavaBeans) is natural interface language
  • JavaBeans can be used at tier 1(client) or 2(server)
Linking this to tier 3 "classic applications" gives rise to JavaBean/CORBA wrappers for existing applications
This turns legacy applications into CORBA distributed objects and so can be remotely executed and documented (via CORBA trader or yellow pages service)
Further these applications now have a visual interface for linking them together in containers and inspecting their parameters

Full HTML Index
This combines TANGO for collaboration with WebFlow to link server side applications
If necessary WebFlowcould support high performance inter-module communication as in structures-CFD Linkage example but it would always implement control at middle tier and this allows TANGO integration with server side computation
  • This illustrates why we keep control at tier 2 so adding collaboration does not disturb high performance layer
WebFlow communication model is a dynamic dataflow
Of course other server side compute models are possible and in general need (web-linked) data bases, file systems, object brokers etc.,
On client one can share tools such as CAD systems like CATIA or AUTOCAD so Tango interfaces with API to these system and drives "slaves" from state extracted from linkage to master.

Reduce cost and increase quality of curriculum and its delivery by
  • Allowing Students access to expertise not available in their own educational institution
  • Use and deliver material to more students than in a typical class so can justify greater effort in preparation
Most important in near term for remote students and new rapidly changing fields which are typically not available
In long term can impact nature of educational enterprise
Important Questions:
  • What is needed network infrastructure in terms of bandwidth and quality of service?
  • What is appropriate way of preparing material and how should it best be delivered
Answers to questions probably depends on field and student body

Universities interact with HPCC in three distinct ways
  • Research in HPCC: This is reduced in level but healthy
  • Using HPCC facilities for large scale simulations in areas like biochemistry and astrophysics: NSF new solicitation with 2 major PACI partnerships signals success and reinvigoration
  • Education of students in field: this is not so satisfactory as in general number of skilled people in computer field is less than demand and students are:
    • Leaving both HPCC areas in computer science (Web, databases appear to have better job opportunities)
    • Leaving major application areas like physics (enrollment dropping)
  • We propose a new educational focus on Internetics to attract students in an area that includes both web and HPCC technologies
  • Also distance education and more enlightened immigration policies can make a major help

Students -- correctly -- perceive a growing opportunity in computer science related fields but outside biology, there is a decrease in interest in "technical sciences" such as physics, aerospace engineering etc.
In particular physics departments may disappear in many Universities as the number of majors is dropping at both undergraduate and graduate level.
Classical Computational Science is not the answer but we suggest that a generalization -- Internetics at the interface between applications and "web/commodity" technologies offers interesting attractive academic programs combining computing and the "technical sciences"
It is not enough to justify physics (as studying Latin and Greek was motivated to me) as "training the mind"

Foil 73 Impact of IT Worker Shortage

From General NPAC Foils-98A starting January 98 (PowerPoint) Computational Aerosciences in the 21st Century Hampton VA -- April 23 98. *
Full HTML Index
So depending on the source, one finds a shortage of 100,000 to 300,000 workers in Information Technology today -- this is forecast to grow with 1 million more jobs created by industry by year 2004
So physics and "physical technology" aspects of engineering (e.g. aerospace engineering) could compete with this trend and try to attract good students from this field
My suggested alternative is to note that IT work typically requires the technical and problem solving skills abilities associated with physics or engineering and often NOT taught in Computer Science
Thus set up new curricula opportunities within the general IT educational arena that we call Internetics
  • IT minor with a basic physics/engineering education
  • Engineering/physics/math methods minor within an IT education
Note IT job opportunities are in applications -- perhaps more so than in "basic systems"

There is the same opportunity available to any education area to use new delivery and preparation methods
  • This opportunity is also a challenge as virtual university opens up teaching at all universities to other providers
Comparing "books" with the Web, we see that Web offers opportunities for "technical people" as well as those with good "communication skills" -- Java applets combined with numerical algorithms may be more effective than streams of beautiful English words
  • Maybe this would suggest new degrees with a mix of engineering, physics, "classical mathematical methods" and Web technology
The new technologies should allow better integration of research into education -- this could help academic fields communicate their value more effectively
