SAGE is on 40 OptIPortals around the world!September 2009 received new NSF grant to support SAGE deployment for next 3 years.
SAGE Roadmap • 3-year plan with the NSF funding • Effort mainly by EVL/UIC and Texas Advanced Computing Center (TACC) • And whoever wants to contribute • Main foci • Production quality : Enhanced Stability • Greater Usability • Deployment in the scientific community • Enable more applications by the community
SAGE Year 1 Plans • Revamp deployment website to include: • Bug tracking, Forum, Community-developed tools, Bi-annual releases (binaries/source), Help desk • Improve reliability/stability • Simplify installation and configuration • Improve user-interaction and content organization • Improve UDP-based streaming • Add new scientific visualization tools • Paraview, Visit, Equalizer • Improve image synchronization between tiles • Hold annual tutorials/BOF at conferences such as SC,Teragrid, Cinegrid
SAGE Year 2 Plans Deploy Paraview Deploy improved interaction and automatic content organization Begin work on real-time compression Refactor audio streaming (multi-channel, mixing, muting, …) Refactor VisualCasting to support more stable content-rich distributed collaboration Begin developing progressive streaming
SAGE Year 3 Plans Interface to common scientific workflow system – e.g. Kepler Continue improving user-interaction Deploy improved audio Deploy improved VisualCasting Deploy compression work

Improved SAGE Inter-Tile Synchronization • Sharp Laboratory of America • Conducted user studies and showed that threshold for being able to perceive sync problems between tiled displays is 10ms. • Also noted that as mullions decrease in size sync problems become more noticeable. • Worked with EVL to develop 2 new algorithms to improve sync: • Two-Phase Algorithm • Scales better when multiple applications are running • Also improved inter-tile synchronization • One-Phase Algorithm • Provides accurate sync • Requires NTP • Consumes more CPU cycles • S.

SAGE – Improved Synchronization Algorithms Inter-tile frame synchronization improved over 100 fold
SAGE – Improved Synchronization Algorithms Scalability in terms of the number of applications improved over 100 fold
