To generate Radphi Monte Carlo events steps below are followed:
- Edit the decayt.dat[1] file and specify the reaction of interest and number of events to generate.
- Run mcwrap[2], mcwrap requires cebaf.geom [3] to run, and specify output name.
- ./mcwrap -l4.390 -u5.390 -comega
- Output file generated with output_name.itape (omega.itape).
- Move this file to the folder Gradphi.
- Edit events.in[4] and control.in[5] files and the run gradphi.x[6].
Resources needed to generate 100000000 events.
- The calculation below is based on 300,000 omega events that were generated using mcwrap and simulated using gradphi on gluey.
- To simulate 300,000 events it took 6840 seconds.
| Number generated(millions) | CPU time per event (s) | Output file size (MB) | Total time in days |
| 100 | 0.0216 | 59000 | 25 |
Results of the simulation
All results from this simulation are stored on the UConn srm. They are available on the UConn cluster in the nfs mounted directory /pnfs/phys.uconn.edu/data/Gluex/radphi/omega_sim-6-2014 or remotely at the srm://grinch.phys.uconn.edu/Gluex/radphi/omega_sim-6-2014 url. Files in this directory are either raw simulation output or reconstructed simulation results in the form of root trees. Files of the former type have the .itape extension and those of the latter type have the .root extension. The file names indicate the simulated channel, as given in the list below.
- 108 events of γ p -> p (ω -> π0γ)
- 100 files of 1000000 events each
- files are named omega_sim_nnn where nnn = 1..100
- 108 events of γ p -> (Δ+ -> p π0) (ω -> π0 π+ π-)
- 100 files of 1000000 events each
- files are named omegaD_sim_nnn where nnn = 101..200
- 108 events of γ p -> (Δ+ -> p π0) (ω -> π0γ)
- 100 files of 1000000 events each
- files are named omegaD2_sim_nnn where nnn = 201..300
