  4. Introduction-PhysicsProjects Experience with Richmondcluster, offsite users. Simulationsfor CLAS12 neutron magnetic form factor GMn experiment (E12-07-104). Quasielastic neutron detection from 2H with forwardTime-of-Flight(TOF) (CN2011-015). Calorimeter(EC) simulation(CN2011-019). ECgeometry simulation (BAPS, DNP, 2012). GMn target simulation (BAPS, DNP, 2011). CLAS12TOFSubsystemsReconstructionSoftware Forward andcentralTOFs. Testedwithgemc. Deep-inelasticscatteringeventgenerator. Richmond cluster is development and test bench for CLARA – used by environment developers.

  5. SoftwareTools General Locally Developed

  6. Simulation EventGenerators pythia localprograms:disgen,ppgen,genev,... Use -Pythiaisa mature,widely-usedprogram.Othercodesvaryin easeof use. Support-PythiawellsupportedbyLundand CERN.Variedsupportforothers. Point-of-contact JLabstaff(H.Avakian). CLAS12Simulation-gemc JLabprogramforCLAS12and others. Useseviodataformatcommonamongthe halls. Use -Scriptsforoffsite installation:time-consuming,butreliable: being improved. Support-Completeweb-page, bugreporting.JLabstaffmember(M. Ungaro). SeeVeroniqueZiegler’stalk.

  7. Reconstruction Socrat(SOftwareforClas12 ReconstructionAnd Tracking) Local,generationone, C++codeforelectrons in forward detector (S. Procureur author). Use -Compiledwith Root libraries(ACLiC), complexcode. Support-CLAS-NOTE2008-015,limited Collaborationsupport. TRAC (TrackReconstructionApplicationforCLAS12) Currentfocusofmaindevelopmenteffortonfull CLAS12 reconstruction. SeeVeroniqueZiegler’stalk. Use -Appliedto otherreconstructionprojects-Forward tagger (offsite) -R.De Vita, BarrelSiliconTracker-Y.Gotra. Support-CLAS-NOTEin preparation.

  8. Visualization -ced12 ced12(cLASeVENTdISPLAY) is the12GeVversionof the 6 GeVapplication. Use - Builton top ofthebCNU libraries.Easy to use. Support- Single Collaboration member (D.Heddle).

  9. PhysicsAnalysis evio2root Convertsevio data into rootntuples. Generation2 versionindevelopment. Use - Generation 1 is easytobuild,butcumbersome to adaptto newbanks. Generation2 being developedbyone JLabstaffmember(M.Ungaro).Generation 1 no longersupported.

  10. Summary Eventgenerators-pythia,ppgen,disgen,and other locallydevelopedones. Simulation-gemcis complete,mature andinwide use. Reconstruction -generation3 developmentfaralong. Visualization-ced12eventdisplay welldevelopedand widelyused. Physics analysis–evio2root gives access to root; improved, generation two version being developed. Ease-of-Use -Many packagesaccessibletooffsiteusers.TRAC juststarting to spreadoffsite. Support-Faculty orJLab staffcontacts for each majorsoftware subsystem(often the originalauthor).
