SAGE: SCALABLE ADAPTIVE GRAPHICS ENVIRONMENT

Scalable Pixel Distribution for High-Resolution Collaborative Visualization on Tiled Displays

SAGE is a graphics streaming architecture for supporting collaborative scientific visualization environments with potentially hundreds of megapixels of contiguous display resolution. In collaborative scientific visualization, it is crucial to share high-resolution imagery as well as high-definition video among groups of collaborators at local or remote sites.

The network-centered architecture of SAGE allows collaborators to simultaneously run various applications (such as 3D rendering, remote desktop, video streams and 2D maps) on local or remote clusters, and share them by streaming the pixels of each application over ultra-high-speed networks to large tiled displays. 

SAGE's streaming architecture is designed so that the output of arbitrary M by N pixel rendering cluster nodes can be streamed to X by Y pixel display screens, allowing user-definable layouts on the display. The dynamic pixel routing capability of SAGE lets users freely move and resize each application's imagery over tiled displays in run-time, tightly synchronizing the multiple visualization streams to form a single stream.

Today’s scientists are tackling issues of global priority -- such as the environment, geoscience, bioscience, disaster response, and the physical nature of the universe, to name a few -- and need the ability to view ultra-resolution images and/or create “cyber-mashups,” or juxtapositions, of information -- a critical component of data analysis -- in order to gain more holistic views and insight regarding complex issues, and make more informed observations and discoveries. read more

SAGEBridge

The use of OptIPortal visualisation walls amongst Australian institutions has grown to a level where interaction beyond the usual point-to-point has become feasible. This has opened up interesting opportunities for multisite collaborations, which are now driving demand for stable middleware to manage such wall-to-multiwall interactions. To further the opportunities of collaboration using SAGE in the Australian research community, the University of Queensland and the Australian Research & Education Network (AARNet) have enabled the deployment of a SAGEBridge trial service with 10Gbps backbone connectivity. read more

GLIF accelerates optical networking

Geneva, Switzerland, October 22, 2010

The 10th Annual Global LambdaGrid Workshop was held on the 13th and 14th of October 2010 at CERN in Geneva, Switzerland. The home of the Large Hadron Collider (LHC) was an appropriate venue as this multinational experiment is one of the biggest users of state-of-the-art optical networking, and also one of the most active participants in the GLIF community. Nearly 100 people attended the event, which included managers, engineers, researchers and developers from national research and education networks (NRENs), universities, research institutions and industry around the world.  read more
