Astro-DISC: Astronomy and Cosmology Applications of Data-Intensive Supercomputing

We are developing new algorithms, data structures, and software tools for the analysis of massive astronomical and cosmological datasets. The goal is to enable the efficient processing of massive astrophysics datasets, with sizes in the tens of terabytes, by scaling up standard algorithms and designing new ones. We are developing programming abstractions and tools to address these challenges and to extend the developed techniques to other fields of science.

RESEARCH AREAS

• Distributed algorithms and data structures
• Indexing and analysis of massive structured data
  
  

CHALLENGES

• Developing distributed versions of standard astronomy applications
• Creating efficient algorithms for new astronomical challenges, in collaboration with astronomers and cosmologists
• Building a general-purpose toolkit for the analysis of massive astronomical observations and cosmological simulations
