DIAL

Distributed Interactive Analysis of Large datasets

DIAL is a PPDG/ATLAS project to develop software and demonstrate the feasibility of distributed interactive analysis of large event data samples.

  Distributed    - processing done on a collection of remote nodes
  Interactive    - response times measured in seconds
  Analysis of    - event selection, filling of histograms and tuples, ...
  Large datasets - more than can be conveniently analyzed in a single process;
                   typically event data

The initial goal of this project is to quickly demonstrate useful analysis of large ATLAS data samples by developing and implementing a design that is easily extended to meet future requirements. We will write code where needed but expect to make extensive use of existing code and the products of other PPDG and ATLAS projects.
