In the demo I will present the new generation SkyQuery, a tool designed for astronomers working on multi-wavelength projects that require cross-matching celestial objects across multiple multi-TB catalogs. Cross-match problems are formulated in a slightly extended version of SQL. Stars and galaxies are associated based on spherical coordinates affected by measurement errors. A Bayesian...

20. Extending the ATLAS PanDA Workload Management System for New Big Data Applications

Dr Alexei Klimentov (Brookhaven National Laboratory (US))

The LHC experiments are today at the leading edge of large scale distributed data-intensive computational science. The LHC's ATLAS experiment processes data volumes which are particularly extreme, over 130 PB to date, distributed worldwide at over of 120 sites. An important element in the success of the exciting physics results from ATLAS is the highly scalable integrated workflow and dataflow...

19. Evaluation of some LSST Queries: Preliminary Results

Prof. Mohand-Saïd Hacid (LIRIS, Lyon 1 University)

In many scientific fields, such as physics, astronomy, biology or environmental science, the rapid evolution of data acquisition tools (e.g., sensors, satellites, cameras, telescopes) as well as the extensive use of computer simulations have led in recent years to an important production of data. Modern scientific applications are then facing with new problems that are primarily related to the...
