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.
