Tracking and Visualizing Evolution of the Universe: In Situ Parallel Dark Matter Halo Merger Trees

SESSION: Research Poster Reception

EVENT TYPE: Posters and Electronic Posters

TIME: 5:15PM - 7:00PM

SESSION CHAIR: Torsten Hoefler

AUTHOR(S):Jay Takle, Katrin Heitmann, Tom Peterka, Deborah Silver, George Zagaris, Salman Habib

ROOM:East Entrance

ABSTRACT:
We present a framework to study the behavior and properties of cosmological structures called dark matter halos. As part of the framework, we build an evolution history, called halo merger trees, which follow the evolution of the halos over time. The entire process from tracking to building the merger tree is performed in parallel and in situ with the underlying cosmological N-body simulation. We are currently in the phase of parallelizing this process for merger tree analysis that will reside in situ in a cosmology application at the scale of millions of processes and is further integrated with a production visualization tool as part of an end-to-end computation / analysis / visualization pipeline. In the poster session we would like to explain the importance of implementing parallel in situ analyses along with effective visualization for cosmological studies and discovery.
