STE||AR at SC13

Next week, the STE||AR team will be at SuperComputing 2013! This year, we will be presenting three HPX demos at the LSU booth (booth 1901) in collaboration with Dell.

  • The Octopus Torus demo is an interactive hydrodynamics simulation of a differentially rotating torus, using Octopus, an HPX AMR framework for Eulerian fluid simulations. Observers can change the numerical methods and underlying physics of the simulation and watch the effects in real time!
  • The vanDouken demo, presented in collaboration with Friedrich-Alexander University (FAU) in Nuremberg, is an artistic interpretation of a full-fledged Particle in Cell simulation with in-situ visualization and live steering. This demo is built on top of the HPX backend to the LibGeoDecomp library. It presents numerical representations of artwork, such as van Gogh’s Starry Night, which can be manipulated by users.
  • Our final demo presents a visualization of a new garbage collection scheme for parallel and distributed systems, which does not require “stopping the world” to reclaim memory. This tablet-based demo allows users to “prototype” various reference counting scenarios, and then visualize how they would be garbage collected.

Thomas Heller will be giving at talk about HPX and LibGeoDecomp at the ScalA 2013 workshop at SC. His talk will be at 11:15 AM on November 18th, in room 507 of the Colorado Convention Center.

HPX V0.9.7 Released!

The newest version of HPX (V0.9.7) is now available for download! Over the past few months the STE||AR Group at Louisiana State University, has been hard at work making HPX more portable than ever before! With the port of HPX to the BlueGene/Q machine, we now can run on almost all of the world’s top 500 machines. We have improved our support for the Intel Xeon Phi ® which will allow HPX users to more fully exploit this exciting accelerator. HPX V0.9.7 will give users the ability to write straight forward code which will automatically utilize the hardware available in their machines and simultaneously be able to run on different architectures around the world.
