Experimental Halls at Jefferson Lab Experimental Program Planned for the Next Ten Years All Halls have collected 12 GeV Data and have operational experience to report that influence computing needs Hall B – understanding nucleon structure via generalized parton distributions Hall D – exploring origin of confinement by studying exotic mesons Hall A – form factors, future new experiments (e.g., SoLID and MOLLER) Hall C – precision determination of valence quark properties in nucleons /nuclei Introduction: Jefferson Lab Computing and Software

A/C Halls Software and Computing Operational experience and path publication for the current program (Hansen & Jones) Towards the future: Focus on Super BigBite Spectrometer (Riordan) Hall C – precision determination of valence quark properties in nucleons /nuclei Hall A – form factors, future new experiments (e.g., SoLID and MOLLER) Introduction: Jefferson Lab Computing and Software

Hall D – exploring origin of confinement by studying exotic mesons Hall D/Glue X Operational experience and path publication for the current program (Meyer) Offsite computing experience OSG and NERSC Towards the future: High Intensity Run Talks by Meyer and Lawrence Hall D – exploring origin of confinement by studying exotic mesons Introduction: Jefferson Lab Computing and Software

Hall B and Focus on CLAS12 Overview of the Hall B program and Computing requirements (Stepanyan) Commissioned in Spring 2018 due to delivery of the solenoid Deep Dive into CLAS12 Software and computing (De Vita & Heyes) Hall B – understanding nucleon structure via generalized parton distributions Introduction: Jefferson Lab Computing and Software

Experimental Computing Performance Plan Responded to DOE recommendation to assess computing needs for Experimental and Theory programs Experimental program: Spreadsheet Model projections (Heyes (II)) key parameters benchmarked against actual performance Construct run scenarios Utilize mix of on-site and off-site resources (Watson, Philpot, Meyer/Lawrence) On-site resources added to farm in August 2018 Projections Usage (Nov 2017-Nov 2018) Introduction: Jefferson Lab Computing and Software 12 GeV S&C Review 2018

Jefferson Lab Agenda The era of 12 GeV Science is coinciding with a revolution in computational techniques and disciplines Machine Learning Data Science Exascale Computing Project Introduction: Jefferson Lab Computing and Software 12 GeV S&C Review 2018

Looking forward…. Will be ramping up to 37 weeks of physics running per year Hurray! With the 12 GeV start-up behind us, this review can look forward towards the 12 GeV program and beyond. Realizing the science requires integration between theory, experiment and advanced data science techniques Three talks on the Future Outlook and gaps: Experimental program (Wood) Scientific Computing (Watson) Links to Phenomenology (Sata) Have also instituted a ‘Grand Challenge’ for computing by grouping existing efforts and LDRD around an organizing principle. Intended to provide a basis for computing and software for the far future, with selected deployments in the late 12 GeV Program An integrated whole-experiment approach to detector readout and analysis towards scientific output will take advantage of multiple existing and emerging technologies.
