Abstract

Large-scale statistical analysis of more than 28 million jobs collected during 20 months of grid activity was undertaken in order to examine the relations between users, computing elements and jobs in the network. The results give insight into the global system behaviour and can be used to build models applicable in various contexts of grid computing. As an example, we here construct probabilistic models that prove to be able to accurately predict job abortion.
