Lamanna et al. Abstract : An OGSA/GT3 evaluation group is active at CERN since GT3 was available in early beta version (Spring 2003). This activity focuses on the evaluation of the technology as promised by the OGSA/OGSI paradigm and on GT3 in particular. The goal was to study this new technology and its implications with the goal to provide useful input for the large grid initiatives active in the LHC Computing Grid (LCG) project. A particular effort has been devoted to investigate performance and deployment issues, having in mind the LCG requirements, in particular scalability and robustness. In this article, the activity and the main results of this activity are summarized.
