Description
The increasing instantaneous luminosity of the Tevatron collider will cause the
computing requirements for data analysis and MC production to grow larger than the
dedicated CPU resources that will be available. In order to meet future demands, CDF
is investing in shared, Grid, resources. A significant fraction of opportunistic Grid
resources will be available to CDF before the LHC era starts and CDF could greatly
benefit from using them. CDF is therefore reorganizing its computing model to be
integrated with the new Grid model. In the case of Open Science Grid (OSG), CDF has
extended its CDF Analysis Farm (CAF) infrastructure by using Condor glide-in and
Generic Connection Brokering (GCB) to produce a CDF portal to the OSG that has an
identical user interface to the CAF infrastructure used for submissions to the CDF
dedicated resources, including its semi-interactive monitoring tools. This talk
presents the architecture of the OSG-CAF and its current state-of-the-art
implementation. We also present the issues we have found in deploying the system, as
well as the solution we adopted to overcome them. Finally, we show our early
prototype which uses the OSG opportunistic workload management system and Edge
Services Framework to harvest the opportunistically schedulable resources on the OSG
in ways that are transparent to the CDF user community.
