Collaboration Arrangements
The level of effort required to design and build projection
versions of the complete Advanced Visualization Toolkit is beyond
funding currently available to a single proposal. The research
proposed here complements other proposals submitted by
colleagues at ANL, LBNL, ISI, and other institutions. These
proposals have been developed with the collective goal of
defining and implementing an Integrated Grid
Architecture for advanced network applications. This
architecture promotes the development of high-performance,
reliable, network-aware application and the sharing of code
across disciplines by the definition of a layered architecture
comprising four principal components:
- At the Grid Fabric level, primitive mechanisms provide
support for high-speed network I/O, differentiated services,
instrumentation, etc.
- At the Grid Services level, a suite of Grid-aware
services implement basic mechanisms such as authentication,
authorization, resource location, resource allocation, and event
services.
- At the Application Toolkit level, toolkits provide more
specialized services for various application classes: e.g.,
data-intensive, remote visualization, distributed computing,
collaboration, problem solving environments.
- Finally, specific grid-aware applications are
implemented in terms of various Grid Services and Application Toolkit
components.
Our experience developing and using both successful Grid
services (e.g., Globus) and substantial Grid applications
convinces us that the definition of such an Integrated Grid
Architecture is essential if the scientific community is to
adopt and profit from NGI environments. Without this architecture, we
will continue to see a range of inadequate, fragile, stovepipe
systems. With it, we can hope to see broad deployment and
adoption of fundamental basic services such as security and
network quality of service, and sharing of code across
different applications with common requirements. We believe
that the DOE's NGI program represents an unprecedented
opportunity to create and deploy such an Architecture, and have
developed our proposals with this goal in mind.
The Advanced Visualization Toolkit will be complementary to much of
the work being proposed in complementary proposals. The Toolkit could
be integrated into the following proposed application proposals,
assuming they are funded beyond a single year:
- Prototyping a Combustion Corridor (led by LBNL)
- CorridorOne: An Integrated Distance Visualization Environment
for SSI and ASCI Applications (led by ANL)
- The Earth System Grid (led by NCAR)
The following basic research NGI proposals could also be integrated
into the Advanced Visualization Toolkit so that their capabilities
could be made available to distributed visualization
applications. This integration effort would be beyond the scope of
this project and would be potentially be completed in the application
proposals.
- Network Monitoring for Performance Analysis and for Enabling
Network-Aware Applications (LBNL/KU)
- A Bandwidth Reservation System (LBNL)
- A Uniform Instrumentation, Event, and Adaptation Framework for
Network-Aware Middleware and Advance Network Applications
(ANL/UIUC)
- Diplomat: Policy-Based Resource Management for Next-Generation
Internet Applications (ANL/ISI/Wisconsin)
