Division Chief: Frank Dallriva

Advisor: Matt Hosseley

Student Research Guest at Center for Science and Engineering Education / Computing Sciences Division at LBNL in the Visualization Group, summer 2004

Topic: Visualization of Discrete Ordinates Method Radiation Transport Data

Mentor: John Shalf

graduate research experience radiation transport
Graduate Research Experience: Radiation Transport

Part of a scientific team interested in discovering the cause of supernovae

Radiation transport involved in key processes taking place in supernovae

Radiation transport describes processes that occur when the properties of protons are altered by scattering, absorption, and reemission of the matter through which the protons are passing

graduate research experience cont d
Graduate Research Experience cont’d

Equation extremely difficult to solve because of the integration on an angle

Scientist uses Discrete Ordinates Methods to circumvent this

DOM divides the domain into regions called ordinates through discretization

Integro-differential form of Boltzmann Radiative Transfer Equation

Discretization of integration over an angle by quadrature sums times appropriate weights at finite points in interval

summer research summary
Summer Research Summary

Provide scientist with tools to explore radiation transport data

Interest in remote distributed visualization

Chose this work in order to gain experience in scientific visualization and to better understand needs and challenges of visualization first

scientific visualization definition

Visualization is a method of computing. It transforms the symbolic into the geometric, enabling researchers to (more effectively) observe their simulations and computations. Visualization offers a method for seeing the unseen. It enriches the process of scientific discovery and fosters profound and unexpected insights...

Distributed Systems: Computational Grids

  • Can support the execution of large-scale, resource-intensive, & distributed applications
  • Distributed systems
  • Linking resources in a geographically remote manner

Distributed Systems: Computational Grids

  • Example of an e-ChemLab enabled by grid technology
  • Spring 2004 special topics course on grid technology
  • Instructed by Drs. Geoffrey Fox, Bryan Carpenter, and Marlon Pierce from Indiana University
distributed visualization motivation
Distributed Visualization: Motivation

Resources and capabilities for visualization are dispersed.

Large data store may be at one site

Special display system at another

High graphics performance processing capabilities may exist at a rendering farm in another site

What if we could create a system to take advantage of all these capabilities in an application that works seamlessly as a single machine?

Remote distributed visualization (RDV) can enable this

Particle Physics




Computation Biology

Any scientific domain that generates huge amounts of data and can take advantage of high performance computing

Distributed Visualization Architecture: Remote Distributed Visualization

Key Problem Areas in Remote Distributed Visualization

New Network Transport and Communications Protocols

Job Control

Brokering of Grid Services for Visualization

Common / Unified Data Formats

New Visualization Algorithms

rdv need for a broker
RDV: Need for a Broker

Possible to manually configure a RDV application on limited number of machines in a distributed environment

Infeasible with many ( hundreds ) of machines and components not to mention that one would have to know all the info about each component

This needs to be automated – could be done by an agent called a broker

visualization services broker
Visualization Services Broker
  • A Broker provides services for:
    • Service/Component Discovery & Location
    • Performance Prediction / Modelling
    • Optimal Configuration
    • Application Invocation
      • Permissions Granting / Acquisition
    • Recording Performance History / Configuration Refinements
