Description
The University of Wisconsin campus research computing grid is an offshoot of Condor
project, which is providing middle ware for many world-wide computing grids. The Grid
Laboratory of Wisconsin (GLOW) and other UW based computing facilities exploit Condor
technologies to provide research computing for a variety of fields including high
energy physics projects on the UW campus. The Condor/GLOW project provided the
largest amount of opportunistic resources to the LHC Monte Carlo simulations,
becoming the leading provider of computing cycles to both CMS and ATLAS experiments.
Together they have provided over 300 years of CPU in 2005 alone, enabling full
simulation of over 20 million events each for CMS, and ATLAS experiments at LHC. The
CMS Tier-2 center in the physics department is being built up to exploit the UW
campus grid to further enhance the use of opportunistic resources for CMS computing.
GLOW also serves chemists, chemical engineers, biologists, medical physicists and
astro-physicists. In addition to building and using the UW campus grid, we have also
developed inter-campus grid job flocking technologies, which we are using to rapidly
aggregate large resources to handle larger than normal peak loads. We have tested
these technologies with our connection to the Open Science Grid (OSG) and Harvard
University facility called the Crimson-grid. In this paper we will describe the UW
campus grid model, the facilities, and its performance. We also discuss the role of
CMS Tier-2 computing center at UW.
