SC12 Demo: Highly Parallel Interactive Image Flow

The Highly Parallel Interactive Image Flow Application (HPIIF) is an interactive visualization built with HPX and  LibGeoDecomp in close collaboration with the Chair for Computer Architecture at the Friedrich-Alexander University in Erlangen (Germany).

Based on an N-Body algorithm, we show a visualization of particles interacting in an otherwise static image. The user is able to interact with the image through a high-definition camera and an Android-based tablet. In addition to the visualization, one can introspect the different performance characteristics through HPX’s performance counter framework. LibGeoDecomp is a generic library for stencil-based simulations. Users program against a common API, while the library leverages a number of optimized components to parallelize the simulation and adapt it to the system. Together with the new HPX backend, this demo showcases automatic load-balancing and dynamic removal/addition of hardware resources.
