mit dem Titel

"Topological Analysis at the Extreme Scale: Finding Features in Large 
Data Sets"


zum Inhalt:

Scalar functions characterize many physical phenomena, e.g., the density 
distribution of particles highlights the structure of the universe in 
cosmological simulations, the fuel consumption rate indicates 
burning/extinct regions in combustion simulations, and the distance from 
a material boundary characterizes the structure of porous materials. 
Since data sizes in all applications grow beyond sizes that can be 
visualized directly, an increasingly important approach is to detect 
salient features in the data and use these features for subsequent 
analysis and visualization. Topological analysis has proven to be a 
powerful tool to detect such features for a wide range of applications 
since it supports feature definitions based on the general concept of 
“connectedness”"and provides means to characterize the prominence and 
stability of features. However, the global nature of topological methods 
makes their parallelization challenging. In this talk, I will present 
applications of topological data analysis and a new approach to 
topological analysis on parallel machines: A new distributed 
representation of topological descriptors reduces the amount of 
communication necessary during their parallel computation and subsequent 
data analysis.


Alle Interessierten sind im Namen von Professor Dr. Scheuermann herzlich 
eingeladen.

Mit freundlichen Grüßen,
