Visualization Update
June 18, 2009
Kelly Gaither, GIG Area Director DV
Background
• 26% of 2008 user survey respondents use
TG resources for interactive visualization,
steering, and data analysis.
• Visualization activities are coordinated
through the Visualization working group
(led by Mike Papka - ANL, and Kelly
Gaither – TACC and coordinated by Joe
Insley, ANL).
– Over the last year, the group has met the first
Tuesday of every month.
• Work over the last year has focused on:
– Reducing barriers to entry and
improving usability through TG
Visualization Gateway and TGUP
visualization portlets.
– Leveraging software and activities
developed at TG RPs.
Software Activities
• TeraGrid Visualization Gateway – community access
via dynamic accounts is in final testing and will be
deployed next quarter. Additionally, a volume
rendering portlet has been added. Paraview is
currently the method for visualization, but VisIt is
being considered as well. (Joe Insley, Mike Papka –
ANL contact)
• EnVision is a web based interface that simplifies
basic visualization capabilities (isosurfaces, particle
traces, cutting planes, etc.). Has been deployed and
is available for public use. (Greg P. Johnson, Kelly
Gaither – TACC contact)
• ORNL is working with Utah to integrate VisTrails into
VisIt (Sean Ahern – ORNL contact)
Software Activities
• New version of Star Splatter viewer for looking at
SPH data (Joel Welling – PSC contact).
• Purdue TeraDRE - supports Maya , Blender, POVray,
and Gelato and allows users to render 3D animations
using a cluster of over 4000 machines (Dave Braun –
Purdue contact).
• IU Render Portal – Condor render portal that uses
available student systems as a distributed render
cluster (Mike Boyles – IU Contact).
• VAPOR – Visualization and analysis platform for
Ocean, Atmosphere and Solar research (John Clyne
– NCAR contact).
TG 09
• There will be a half day visualization tutorial at TG 09
that currently has approximately 35 attendees –
participation from ANL, TACC and NCAR.
• The “Visualization Gallery” will happen again this
year:
– 12 visualization submissions
– Will be displayed on Tuesday night with the reception
Current Efforts:
• Visualization working group is working on a white
paper to lay a foundation for the future directions for
petascale visualization and data analysis.
– The group meets once a week on Wednesdays at 3pm
– Current material is on the wiki at
http://www.teragridforum.org/mediawiki/index.php?title=V
isualization#Petascale_Visualization_and_Data_Analysis_W
hite_Paper
– We will distribute the first version of the white paper at the
science advisory board for comment from the community
– Second version will be distributed to the TG forum for the
Sept quarterly meeting
Future Efforts:
• NSF has recommended that two resources be
funded for the XD Vis program
– First is a large shared memory machine that will primarily
focus on large scale data analysis and data mining with
visualization capabilities
– Second is a large distributed memory machine that will
primarily focus on large scale remote interactive
visualization and will provide data mining and data analysis
capabilities
