Collaborative Visualization over the Access Grid

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.
