Infrastructure

The job submission middleware installed at CNAF Tier1 is HTCondor. The infrastructure consists of:

• sn01-htc.cr.cnaf.infn.it: a submit node for submission from local UIs (HTCondor 23 25 cluster, current).sn-02.cr.cnaf.infn.it: a submit node for submission from local UIs (HTCondor 9 cluster, decommissioned).
• ce01-htc.cr.cnaf.infn.it:9619,ce02-htc.cr.cnaf.infn.it:9619, ce03-htc.cr.cnaf.infn.it:9619, ce04-htc.cr.cnaf.infn.it:9619, ce05-htc.cr.cnaf.infn.it:9619, ce06-htc.cr.cnaf.infn.it:9619, ce07-htc.cr.cnaf.infn.it:9619: 6 computing elements for grid submission.
• 1000 650 worker nodes.

From a UI, the user can submit a job to the submit node, which then deals with the routing to the central manager, responsible for dispatching the jobs to the worker nodes.
