Survey and Analysis of Production Distributed Computing Infrastructures [article]

Daniel S. Katz, Shantenu Jha, Manish Parashar, Omer Rana, Jon Weissman
2012 arXiv   pre-print
The reader should understand how the interplay between the infrastructure providers and the users leads to such usages, which we call usage modalities.  ...  Second, we describe the infrastructures in terms of their use, which is a combination of how they were designed to be used and how users have found ways to use them.  ...  OSG provides access to and sharing of resources through common, shared services for monitoring, accounting, security, problem reporting, and tracking.  ...
