Description

The multi-user pilot job (MUPJ) model has become deeply embedded in the LHC computing ecosystem. In this model, the pilot job sent to a site batch will dynamically pull down one or more user payload jobs as it is running at the site.

While providing the experiments with utmost flexibility, the MUPJ presents challenges in isolation (preventing payloads from interacting with the pilot) and traceability (helping the site understand who is utilizing their resources). The traditional approach to provide traceability and isolation has been to utilize glexec.

In this talk, we will provide an overview of the search for new technologies to fulfill the traceability and isolation requirements. We fill focus on work within the OSG to utilize singularity for isolation and the HTCondor-CE for traceability.
