With the ProtoDUNE assembly and operation rapidly approaching, as well as the technical design report, DUNE is putting substantial work into developing software and provisioning computing resources. Smaller teams are turning into bigger ones as the collaboration grows, which has prodded DUNE to rethink the distribution of software and computing efforts.
Early last December, DUNE held a two-day Software and Computing (S&C) retreat at Fermilab. At this retreat the spokesperson and the S&C coordinators met with the physics and ProtoDUNE working groups to discuss the roles to fill and the tasks to accomplish relating to these areas. In the process, they updated the organizational structure, redistributing both the roles and reporting structure.
Much of the software developed by the DUNE collaboration is tied tightly to the physics output, for example, detector simulation, reconstruction, event selection, and analysis. The physics-based software efforts for the DUNE experiment therefore now report directly to the physics coordinators rather than the computing coordinators. This change provides a more direct coupling between collaborators who simulate and reconstruct the data and those who compute sensitivities and extract results. Similarly, ProtoDUNE simulation and reconstruction groups now report to the ProtoDUNE coordinators. With much commonality between the single-phase, dual-phase, and far detector simulation and reconstruction, the memberships of these groups overlap significantly.
The “computing” side of the effort includes groups responsible for the data handling, storage and processing, and the management of databases, software and collaborative tools. These groups, currently largely made up of laboratory staff but open also to university researchers, coordinate closely with the DAQ group and report to the DUNE and ProtoDUNE computing coordinators.
The computing coordinators also interface with laboratory computing staff to request resources and to coordinate details of their usage. They have also been working with the recently restarted Fermilab/CERN/DUNE Interface Group to identify the computing resources needed to ensure the success of the ProtoDUNE experiments.
The coordinators of these newly rearranged Software, Physics, and Computing working groups encourage and welcome both new collaborators and old hands to sign up to work! Contact firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, or email@example.com.
