The ability to transfer multi-gigabyte objects among remote collaborating sites is an enabling technology for the Earth sciences. For this demonstration, the OptIPuter’s Distributed Virtual Computer (DVC) middleware is used to establish a collaborative environment with visualization endpoints at UCSD and UC-Irvine. OptIPuter’s Composite Endpoint Protocol (CEP) and Group Transport Protocol (GTP), two cluster-to-cluster transport protocols, are used to efficiently send multi-gigabyte 3D scene files from the various storage sites for interactive visualization on tiled displays at the visualization sites.
