Batch Service

The CERN Batch Service provides computing power to the CERN experiments and departments for tasks such as physics event reconstruction, data analysis and simulation. It aims to share the resources fairly and as agreed between all users of the system. The service supports both local jobs, and WLCG grid jobs via the HTCondorCE.

The current batch computing service currently consists of around 190,000 CPU cores - mostly deployed in the HTCondor based service.

Supported Clients

Please visit the HTCondor User's Guide for detailed instructions on how to use the Batch Service.

Legacy LSF users can still submit jobs to the service using the normal LSF commands from the LXPLUS service. The Batch Service team is available to help you migrate to the new system - please contact the Service Desk.
