CMS Connect is a service that aims to provide CMS users Tier 3-Like access to any resources available (via this service) for non-CRAB 3 workflows, e.g late-stage non-cmsRun analysis jobs.
It is based on the CI-Connect Platform developed by the OSG Area Coordinator of Campus Infrastructures Rob Gardner and his team at the University of Chicago. CI Connect offers several capabilities leveraging technologies on well-known projects like Globus, HTCondor and other HTC and data sharing technologies and allowing a home campus identity infrastructure via CILogon and InCommon Federation Services. See this link for more details on this platform.
Figure 1 shows a basic schematic for this platform. Where the Portal (http://connect.uscms.org) and login node (login.uscms.org for EL6 and login-el7.uscms.org for EL7) are hosted and handled by the University of Chicago. The Job Routing is configured to flock jobs over the CMS GlideInWMS Pool.
