The SAM-Grid / LCG Interoperability Project Report of the trip to Lyon

Goal of the SAM-Grid / LCG interoperability project is making available to DZero the resources provided by the LHC Computing Grid (LCG) through the SAM-Grid system. In the months between March and June, the collaboration has put in place a “proof-of-principle” test bed, which demonstrated the feasibility of the integration project. The trip to Lyon was an intensive, strict collaboration with the LCG experts, in order to move the testbed to a “proto-production” stage. This document reports the achievements of the trip, describes the status of the current test bed, and suggests a path toward production.
