source code location

pythia6 docker container https://github.com/eictool/container/blob/master/log_evgen_pythia6

mRICH in JLEIC det1 https://github.com/EIC-eRD11/det1_rich_modular_eleside

dRICH in JLEIC det1 https://github.com/EIC-eRD11/dualRICH_inMEIC/tree/master/gemc_drich/aerogel_c2f6

running simulation and analysis

general instruction running GEMC on ifarm at https://eic.jlab.org/wiki/index.php/EIC_Software#on_ifarm

run code in graphic mode on ifarm https://hallaweb.jlab.org/wiki/index.php/Ifarm_graphic_mode

The code to run farm jobs are at /work/eic/sim/eic_gemc/JLAB_VERSION_1.3/RICH

run "./LongRun_sim" and Give the start run number as 1, then Give the end run number 100. 100 jobs will be launched.

"LongRun_sim" calls "exec_sim" to create farm job submission script and submit them. Each job runs the main code "do_it_all.sh"

check job status "jobstat -u $USER" and log ~/.farm_out/

refer to jlab farm https://scicomp.jlab.org

simulation data location

They are at jlab disk location

/work/eic/sim/eic_gemc/JLAB_VERSION_1.3/RICH/
/cache/eic/sim/eic_gemc/JLAB_VERSION_1.3/RICH

with dir as follows
output_flat_geo1gen1
output_pythia6_geo1gen1

geo1 means geometry version 1, gen means generator version 1
see readme in each to see detailed version info
each version has a nofield and yesfield subdir for turning solenoid field off and on cases

simulation files have both RICH
each pythia6 file has 1e3 events and about 1GB size 
each flat file has 1e4 events and about 1GB size 
pythia6 events has no selection of channels
flat events include pi,kaon,proton in each events

The easiest way would be running your analysis script at jlab ifarm to process the data Or you have to download them by using scp from ftp.jlab.org with your jlab account or via globus (about 2x faster with some setup effort)

working at jlab ifarm

ssh -X your_jlab_username@login.jlab.org

ssh -X ifarm

source /group/eic/eic_svn/set_eic (this set up env for simulation including a root)

cd /work/eic/(your_jlab_username)
