Abstract : This thesis combines high performance computing and virtual reality to design parallel components coupling methods inside distributed interactive applications.
A new coupling model designed with modularity, simplicity, efficiency and extensibility criteria is presented. Applications are constructed following a two phases process : programming reusable parallel components, and defining the application as a data-flow graph with filtering and synchronisation mechanisms, expressing advanced collective communication schemes and coupling policies.
An extension of this work is presented for distributed rendering. Using a modular scene description based on independent shader-based primitives, filtering networks are designed to efficiently combine multiple graphics streams up to the rendering nodes. This framework scales well and allow the creation of new applications, exploiting the graphics cards' power to remove computations from CPUs which reducing network communications.
Several innovative applications are created using these tools. They includes parallel computer vision algorithms, immersing the user inside a virtual world, which can then interact with objects controlled by several distributed physical simulations (carving, collisions, fluids).
