【 摘 要 】

One of the fundamental problems in remote visualization --where I/O and data intensive visualization activities take place at acentrally located supercomputer center and resulting imagery is deliveredto a remotely located user -- is reduced interactivity resulting from thecombination of high network latency and relatively low network bandwidth.This research project has produced a novel approach for latency-tolerantdelivery of visualization and rendering results where client-side framerate display performance is independent of source dataset size, imagesize, visualization technique or rendering complexity. As such, it is asuitable solution for remote visualization image delivery for anyvisualization or rendering application that can generate image frames inan ordered fashion. This new capability is suitable for use in addressingmany of ASCR s remote visualization needs, particularly deployment atopen computing facilities to provide remote visualization capabilities toteams of scientific researchers.
