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 computing
/mss/eic/sim/eic_gemc/JLAB_VERSION_1.3/RICH/ tape location which can't be access directly.
/lustre/expphy/cache/eic/sim/eic_gemc/JLAB_VERSION_1.3/RICH disk location which can be accessed directly, files are gone back to tape if not used for a while, can get back from tape by "jcache get file_fullpath_on_mss", refer to https://scicomp.jlab.org/docs/%20 dir structure as follows output_flat_geo1gen1/yesfield output_flat_geo1gen1/nofield output_pythia6_geo1gen1/yesfield output_pythia6_geo1gen1/nofield simulation files have both RICH each pythia6 file has 1e3 events and about 1GB size, about 1000 files or 1TB are done for pythia6 file with and without field as of 2018/06 each flat file has 1e4 events and about 1GB size about 100 files or 100GB are done for flat file with and without field as of 2018/06 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 your_jlab_username@ftp.jlab.org:file_or_dir_fullpath" or via globus (about 2x faster with some setup effort)
version info
geo1 means geometry version 1, gen means generator version 1

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)
