Foil 5 Collaboration with CAPS

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index
We had a meeting with CAPS during the last week of April, and the outcome is the following:
  • They will supply us with an initial data set over the Syracuse region.
  • This data set will be taken from the end of April, during severe thunderstorms in the region.
  • By mid summer they will try to help us run the code to evolve the initial data.
    • The first attempts should result in stable runs, with inaccurate predictions.
  • The ETA of accurate simulations should be roughly 1/2 person year.
    • This will time line would allow for the accurate prediction of lake effect snow.
    • Lake effect snow is caused mostly from wind blowing over a cold lake.

We will use the current output from ARPS in hdf format.
We will visualize the moisture variables.
  • We run an isosurface routine on the raw data, which generates output of cloud formation.
  • Will are developing a Java applet which will read in 3D data and determine isosurfaces.
    • The user will input the isosurface value from a WWW page running the applet.
    • The output of this applet will be VRML data that will be instantly rendered.
    • Also it can be stored in our Illustra object database
For the integration of the weather data to the existing 3D VRML terrain data set, we will use a 2D mask function which will determine where snow has fallen to a certain level.
VRML data will be stored in a database, allowing the user to interactively turn on and off the weather information over the terrain.

Foil 7 Aspects of Financial World Motivating HPCC

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index
Cooperative distributed (and parallel) computing will become mainstream in financial engineering due to a convergence of the following factors:
Increased volatility due to globalization of financial markets
Global distribution of data sources
Increase in complexity of derivatives and risk management vehicles
Increased demand for real-time asset allocation decision support
Increased volume of raw data and need to process large databases
Increased volume on the retail side of the spectrum in part due to on-line technologies (Internet and WWW)

Foil 8 Financial Application areas for which High-performance computing technologies are becoming indispensable

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index
HPCC is becoming indispensable in the application domains such as:
  • Derivative Valuation -- particularly over-the-counter products and exotics
  • Portfolio optimization, valuation and asset allocation
  • Hedging of large portfolios in real time
  • Arbitrage trading
  • Risk analysis simulations
  • Pattern recognition
  • Detection of fraud
  • Credit risk analysis
  • Market segmentation
NPAC is engaged in development of new tools for quantitative financial modeling which take advantage of scalable computer architectures
The ultimate goal is to integrate various quantitative analysis transparently using Web technologies into a seamless cooperative computing environment, capable of supporting all aspects of enterprise-wide risk management.
HTML version of Basic Foils prepared 12 May 1996

Foil 9 Path Integral Approach to Derivative Valuation

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
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

Foil 10 Parallel Maximum Entropy and optimization

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
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

Foil 11 Web-based System Integration -- Initial Server Implementation

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index
Derivative valuation functions are integrated using Web technologies into a service which can be accessed from any platform which supports a graphical browser
Using a combination of HTML forms or Java front-end, CGI mechanism, Perl scripts and modules written in C and MPI, which are executed on multiple NPAC RS 6000 and Sun workstations and the SP-2, the user can:
  • retrieve historical data from flat files
  • perform statistical analysis
  • display charts and histograms of historical data
  • estimate parameters of the underlying stochastic processes
  • enter own estimates of model parameters
  • perform simulations
  • display charts and plots of option prices and their sensitivities as functions of time, underlying stock price or option contract excercise (strike) price
HTML version of Basic Foils prepared 12 May 1996

Foil 12 Web-based System Integration -- Futures

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index
In the next stage, flat files will be replaced with a parallel Oracle server
Ultimately, the graphical user interface will be supplemented with an agent-based middleware layer, implemented in Java, where derivative pricing and risk management services will be requested and dispatched to the parallel Monte Carlo engine and returned to the client using an EDI-like protocol encapsulated within the KQML envelope.
This will be a prototype of the new service economy that will flourish on the Web.

Einstein's equations can be represented as a coupled system of hyperbolic and elliptic PDEs with non-trivial boundary conditions to be solved using adaptive multilevel methods
We are building PSE that will support:
  • composition of stable, convergent AMR and MG solvers
  • software integration (initial value problem, apparent horizon finders, ...
  • automatic conversion of sequential unigrid codes into parallel, multigrid versions
  • collaborative visualization environment
To implement the system we use technologies developed by CRPC, in particular MPI and HPF, combined with emerging new Web technologies: JAVA and VRML 2.0.

Foil 34 HPF and DAGH Implementation Strategies

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index Secs 53
Main Approach is DAGH: Distributed Adaptive Grid Hierarchy (J. Browne, M. Parashar at Texas )
  • a set of programming abstractions in which computations on dynamic hierarchical grid structures are directly implementable (C++).
  • a set of distributed dynamic data-structures providing transparent scalable distribution of the grid hierarchy across processors (MPI).
  • a set of computational modules and AMR/MG support (shared with HPF when HPF supports this adaptive data structure)
  • (http://godel.ph.utexas.edu/Members/parashar/DAGH/dagh.html)
HPF (Syracuse) relegated to reserve status
  • data parallel implementation of unigrid PDE solvers as HPF does not support necessary distributions
  • Fortran90/HPF dynamic memory management
  • (http://www.npac.syr.edu/projects/bbh/more.html)
DAGH is similar model to HPF with much less general capability but excellent support for AMR data structures and distribution

Foil 38 HPF: Some Problems we found

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index
We find that our best results with HPF codes come from those designed as parallel codes.
Traditional Model of "dusty deck + HPF directives" often does not work well.
Is not as intuitive as expected. Students have problems with getting performance. Reasons:
  • Poor knowledge of Fortran 90.
  • Many "details" are not handled well without some code massaging. Often HPF actions are highly non intuitive for inexperienced users.
  • Poor and cryptic compiler diagnostics and feedback.
  • Profilers (both PGI and DEC) help to identify sources of inefficiencies, though.

Foil 39 Special Problems with PGI HPF Compiler

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index
PGI Compiler is typically very succesful but ..
PGHPF is a translator, not a "real" compiler.
We encountered situations that the fortran 77 code generated by PGHPF cannot be compiled by the native IBM xlf compiler at a decent optimalization level (O3) which leads to a lousy node performance (with linear parallel speedup).
We suspect that the problem lies in array's index expressions which are always one dimensional(?).

Full HTML Index
http://www.npac.syr.edu/users/bernhold/comp_chem
Use of modeling in chemistry has exploded
in recent years, driving the push for larger
and more accurate calculations to simulate
"real world" chemical phenomena.
Chemistry applications range in cost from N2 to N4, N6, and higher (N proportional to the size of the molecule). Can be both CPU- and memory-intensive.
Interested both in legacy and "HPCC-designed" applications
  • Existing codes are often quite large (100,000+ lines) and embody perhaps decades of effort -- not rewritten lightly!
  • Many legacy codes can be retrofitted with simple parallel algorithms that allow reasonable efficiency for small-scale parallelism on local resources (including NOWs).
  • Large-scale calculations require parallel computing using a distributed-data model. Naive parallel algorithms are generally insufficient. Requires codes constructed from scratch.

Foil 57 HPJava Study Rationale

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index
Java is rapidly becoming a dominant distributed computing language driven by the the breadth and depth of the World Wide Web.
  • It implements a natural object or Applet distributed parallelism combined with a
  • classic light weight thread mechanism within a given applet i.e. within a given (SMP) processor.
HPCC has developed technology and the application pull for large scale computation with typically tighter synchronization constraints than those of Java.
Further HPCC can benefit from the pervasive software base illustrated by Web in general and Java in particular.
Correspondingly there are many emerging Web based applications which will need large synchronized computation.

For these reasons, we thought it useful to examine the confluence of HPCC and Java -- referred to as HPjava.(without knowing what this is!)
In particular it is natural for PCRC to examine its software indrastructure and see how it should be structured/changed to support HPJava.
http://www.npac.syr.edu/users/gcf/hpjava3.html is not a proposal or plan.
  • Rather it is an often conflicting(!) study of issues that emerge when you place Java and HPCC next to each other.
  • Is data Parallelism useful in Java is Controversial!
More thoughtfully, we study Programming Model suggested by HPJava
What is Role of Optimizing Compilers in (HP)Java?
  • What are performance issues -- can we separate out current implementations from intrinsic issues.
There are a large number of important experiments in the community
Other topics include role of CORBA, Security, Model for communication in Java

Full HTML Index
We adopt a broad view/definition of Problem Solving Environment as a distributed system capable of attacking complex, so far unsolvable problems by integrating information and computation.
  • This includes both scientific and large scale enterprise computing systems.
Development of such systems was slow/inefficient so far due to the separation of (lower end) PC computing world (focused on productivity tools for information processing such as authoring or database) and (higher end) UNIX computing world (focused on HPCC)
Both platforms become now integrated by the Web phenomenon in the form of what we called WebWindows paradigm.
Hence, Web based distributed computing within the WebWindows framework offers a novel, unique and powerful model for PSEs that include and integrate NII and HPCC components.

There is still no single large scale killer application but rather a growing set of Intranet based information/computation systems that use open Web technologies to prototype proprietary systems for internal corporate use in a more cost effective fashion that in the PC/Windows framework

Netscape3 is out with support for Live3D (inlined VRML) and CoolTalk (Internet Phone). LiveMedia (inlined video based on OpenDVE/RTP) is coming soon. FastTrack Web servers offer now page authoring, site management, mailing services, scripted database interfaces and so on. A mortal Netscape-Microsoft war is imminent.
Meanwhile, JavaSoft expands with a different strategy , by collaborating with Microsoft, seeking new niches such as support for transparent database backends (JDBC), distributed computing (DMI), CASE tools (JDE) and open browser technology (beta HotJava), family of extension API's -- Media, Commerce, Security, Collaboration .
Meanwhile, Sun attempts at JavaVM based JavaOS and GNU is addressing open multiplatform JavaVM implementation.

We correctly predicted the "revolution" and the current "expansion phase" in our WebWindows presentation at the CRPC annual meeting 1 year ago in Houston.
What was a prophecy 1 year ago, becomes everyone's idea today. What is still non-trivial is the proper strategy for academic computer science, given the unprecedented speed of the Web expansion and rapidly melting boundaries between Windows and UNIX.
We view the area of distributed Web based computing for PSE as a promising niche, given that industry will continue their focus on client-server aspects of the Web where the near term profit can be made.
We expect Web based PSE to evolve starting from the top-down Web interfaces to previous generation legacy systems (current state-of-the-art) and moving towards genuine bottom-up Web infrastructure (WebWindows).

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.

Typical CareWeb databases include: Customers, Connections, Transactions, Schools, Teachers, Nurses, Nurse Practitioners, Doctors, and Record Components such as Immunizations, Screening Tests, Health Histories, Progress Notes, Visit Logs, Assessment Forms etc.
CareWeb Information Pages offer customized educational support for healthcare personnel as well as students and parents, as well as decision tree support to be used in the next project stage for the agent-based automated diagnosis generation and verification.
Interactive consulting is based on shared record pages, optionally synchronized via phone chat or/and WebCast support, and VIC/VAT video support for 'talking heads' and/or video feeds from (Welch Allyn) multi-purpose fiberscopes for ear, nose and throat inspection.
The system offers multi-level security, including Internet guests (with anonymous limited access), CareWeb friends (with registered restricted access) and CareWeb customers (nurses, nurse practitioners, doctors, parents) with secure password based access, individual home pages and customized information/operational spaces.

RSA Factoring-by-Web -- collaboration with Arjen Lenstra and Boston/CSC. New NFS factoring algorithm successfully applied to RSA130 factoring on a tree of Web+CGI servers (FAFNER by Jim Cowie/CSC). SC'95 Teraflop Challenge Award. Next Challenge -- RSA155.
WebHPF -- Web front-end to HPF compiler and PVM-based distributed runtime. Supports CASE tools for program development, process management and performance monitoring.
Adaptive Mesh Refinement -- planned WebVM/WebFlow application to support Grand Challenge PDE solvers. Includes static AMR trees specified by visual authoring and dynamic trees, implemented via interactive scripting modules.
Visible->Virtual Human -- 3D reconstruction of the human body, based on the image database from the National Library of Medicine. Currently implemented is color segmentation stage (embarrassingly parallel), to be followed by WebVM/WebFlow based algorithms with non-trivial internode communication (surface reconstruction, object labelling and grouping).

Foil 79 Next Steps in Visual Programming for Chaining and Aggregating Services -- WebFlow!!

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. *
Full HTML Index
New powerful Web'96 technologies from Netscape, JavaSoft, Oracle, NeXT etc. will result in a new generation of interactive services
A natural next step is to start Chaining (Integrating) such services to a distributed PSE by providing a server to server communication and dataflow support
However Web'96 becomes also increasingly complex with its competing and overlapping multi-lingual standards
  • HTML, CGI, Perl, Java, JavaScript, LiveWire, VRML, VRMLScript
Visual Programming for a multi-server Web (We call it WebVM) based dataflow (we call it WebFlow) is a natural next generation user-friendly programming environment
We view the area of distributed Web based computing for PSE as a promising niche for NPAC and academic R and D where we expect industry to continue their focus on client-server aspects of the Web where near term profits can be made
