helping MINERvA with offline production
has been using offline production from OPOS for over a year. The
following picture shows almost 200,000 jobs from MINERvA between June
and December of 2015. (Note:
DUNE's part of the graph only covers December since they started
until OPOS on November 30, 2015.)
started by using just monitoring services from OPOS, but now the team
is running Monte Carlo (MC) simulation as well. It is anticipated
that more services from OPOS will be used in the future.
The following quote is from the MINERvA spokespeople to the team. “OPOS takes on the task of submitting and monitoring grid jobs for MINERvA. This frees up the MINERvA personnel working on production, simulation and data analysis to spend time optimizing these processes to minimize resource use and maximize reliability. In addition, OPOS is able to identify common problems among experiments and to track statistics of analysis job performance and reliability. This data also proves essential for efficient processing and analysis of MINERvA data. Their efforts add up to more reliable and faster analysis of experimental data, which in turn allows MINERvA to continue to rapidly publish high quality physics papers."
of the benefits of running production jobs for several experiments is
that experience can be shared. For example:
OPOS helped NOvA create procedures for running Keepup jobs. OPOS later helped MINERvA create their procedures using that work. Setting up these jobs was easier because of the experience of the OPOS team.
OPOS helped MINOS change their workflow so they could use the samweb tool. OPOS can transfer this successful work to MINERvA to enable them to begin to use samweb.
