Data analysis and visualization plans
The Data Analysis Services Group (DASG) will continue to support the UCAR
scientifc community through further enhancements in the VisLab environment,
and significant progress on the design of a new advanced computing environment
tailored to the specialized needs of interactive data post-processing,
analysis, and visualization. Staff will continue to support the special needs
of the UCAR scientfic community in the areas of visualization research and
algorithm development and assistance with the production of animations and
imagery. The following are key activities planned for FY2006.
Production visualization services
DASG will continue to provide visualization services for the most
demanding scientific datasets generated by the UCAR community. Current
planned activities for FY2006 include:
Continuing collaborations with CISL's Computational Sciences Section
on the HOMME model. Specifically, DASG will generate new visualizations
and work toward delivering simple visualization tools aimed at aiding
diagnostics for HOMME.
Visualizing observed upper atmosphere ozone data for ACD.
Visualization Lab upgrade project
In FY2006, DASG will continue its efforts to further transition from
proprietary to commodity technologies. These measures are aimed at both
saving cost and exploiting rapid technology advances in many aspects of
the commodity space. DASG will also begin exploring steps to better
integrate visualization and data analysis resources as described in
the analysis environment project below.
Specific items planned for FY2006 include:
Replacing the VisLab's five-year-old tiled, stereo projection system
with current vendor offerings. Though it is unlikely that a commodity
solution will present itself in this case, the current display
environment suffers from a number of pitfalls that should be addressed
(e.g. poor image registration, brightness and color balance between
projectors, the need for multiple image generators, and the highly
reflective and distracting silver screen required for passive stereo
projection). Products anticipated to become available this year would
allow the replacement of the current multi-projector display with a
single projector that would address all of the present environment's
shortcomings.
Further evaluating the small 64-bit visualization cluster deployed
in FY2005, and pending results, acquire additional nodes allowing us to
retire the lab's costly Onyx4-based remote visualization service.
Replacing the VisLab's five-year-old Fibre Channel RAID storage
system with a RAID device based on commodity SATA drive technology.
Analysis environment project
The analysis environment project addresses several key components in
moving us toward a high-performance analysis environment, on par with
NCAR's renowned supercomputing capabilities. The project began in FY2005
with the research necessary to define the architecture for a new analysis
environment. The next step is the installation of a testbed and subsequent
analysis of test results. The project ends with recommendations for a
production environment, an implementation plan, and the installation of
new resources in FY2007.
The following project phases are planned for FY2006:
- Activities in phase one focus on initial research into available
technologies and the construction of a test environment. Specific goals
in phase one include:
- Basic architectural research, including reviewing previous research
conducted by SCD.
- Initial vendor contacts to ensure we choose promising resources
for the testbed.
- Visits to sites that have already integrated similar solutions.
- Aquisition and installation of initial testbed equipment.
- Development of benchmarks for analysis and visualization
environments.
- Development of testing criteria for storage and file system
solutions.
- Activities in phase two will focus on the evaluation and integration
of a high performance, heterogeneous, shared file system and the
evaluation of computational resources for use as analysis platforms.
Specific goals in phase two include:
- Identifying a suitable shared file system technology and
characterizing the needs for its performance and capacity.
- Identifying suitable computational nodes based on performance,
supported software stack, interoperability, and maintainability.
- Expanding the testbed to include all architectures supported
by SCD.
- Developing policies and mechanisms for allocating nodes and
storage space.
- Initial investigation of visualization integration.
