4. 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

5. A/C Halls Software and Computing

7. 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

8. 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)

10. 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.
