Description
Hadron Collider experiments in progress at Fermilab’s Tevatron and under construction
at the Large Hadron Collider (LHC) at CERN will record many petabytes of data in
pursuing the goals of understanding nature and searching for the origin of mass.
Computing resources required to analyze these data far exceed the capabilities of any
one institution. The computing grid has long been recognized as a solution to this
and other problems. The success of the grid solution will crucially depend on having
high-speed network connections, the ability to use general-purpose computer
facilities, and the existence of robust software tools. A consortium of universities
in the US, Brazil, Mexico and India are developing a fully realized grid that will
test this technology. These institutions are members of the DØ experiment at the
Tevatron and the ATLAS or CMS experiments at the LHC, and form the Distributed
Organization for Scientific and Academic Research (DOSAR). DOSAR is a federated grid
organization encompassing numerous institutional grids. While founded for HEP
research DOSAR forms the nucleus of grid infrastructure organization on the
constituent campuses. DOSAR's strategy is to promote multi-disciplinary use of grids
on campus and among the institutions involved in the consortium. DOSAR enables
researchers and educators at the federated institutions to access grid resources
outside the HEP context and is a catalyst in establishing state-wide grid structures.
DOSAR is an operational grid which is a Virtual Organization (VO) in the Open Science
Grid (OSG). In this talk, we will describe the architecture of the DOSAR VO, the use
and functionality of the grid, and the experience of operating the grid for
simulation, reprocessing and analysis of data from the DØ experiment. A software
system for large-scale grid processing will be described. Our experience with
high-speed intercontinental network connections will also be discussed.
