Using the Access Grid to collaborate with colleagues has gained widespread acceptance, with the collaborations commonly taking the form of shared audio, video and PowerPoint presentations. This demonstration shows next-generation Access Grid applications, where the Access Grid is coupled to high-speed networks and vast computational resources. Using the Globus Toolkit, MPICH-G2 and Access Grid technology, scientists can collaboratively and interactively analyze time-varying datasets that are multiple terabytes in size.

Users first collaborate over the Access Grid to explore lower-resolution datasets in real time, in order to find areas of interest for detailed study. Then, using multiple distributed compute resources and a high-speed network, full-resolution high-quality images are produced and delivered to a tiled display. This demonstration shows how scientists can enhance their work environment by having easy access to worldwide resources.
