Analysis of Jobs in a Multi-Organizational Grid Test-bed

The inevitable move from a single large scale server to a distributed grid environment is beginning to be realized across international grid test-bed like Pacific Rim Applications and Grid Middleware Assembly (PRAGMA).

This paper reports on the analysis of jobs submitted across the PRAGMA grid test-bed. The job types are categorized and the runtime of jobs is captured, using the Multi-Organization Grid Accounting System (MOGAS), and analyzed. The number of jobs submitted across organizations, indicating the level of resource sharing among participants, is also captured by the system
