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 For Questions: • Email Kelly Gaither at [email protected] or to get the entire vis working group, email [email protected].
