Final Project
A final project will be submitted that will be graded with the following metrics:
1.) The document must be less than 15 pages.
2.) The document must contain references in a bibliography (5 points) .
3.) A comparison must be made between GEANT4's prediction and either the prediction of someone else or an experimental result(30 points).
4.) The graphs must be of publication quality with font sizes similar or larger than the 12 point font (10 points).
5.) The document must be grammatically correct (5 points).
6.) The document format must contain the following sections: An abstract of 5 sentences (5 points) , an Introduction(10 points), a Theory section (20 points) , if applicable a section describing the experiment that was simulated, a section delineating the comparisons that were made, and a conclusion( 15 points).
Resources
Saving/restoring Random number seed
You save the current state of the random number generator with the command
/random/setSavingFlag 1
/run/beamOn 100
/random/saveThisRun
A file is created called
currentEvent.rndm
/control/shell mv currentEvent.rndm currentEvent10.rndm
You can restore the random number generator and begin generating random number from the last save time
/random/resetEngineFrom currentEvent.rndm

Compiling G4 with ROOT
These instruction describe how you can create a tree within ExN02SteppingVerbose to store tracking info in an array (max number of steps in a track is set to 100 for the desired particle)
Using SLURM

https://rc.fas.harvard.edu/resources/documentation/convenient-slurm-commands/
simple batch script for one process job
create the file submit.sbatch below
#!/bin/sh #SBATCH --time=1 cd src/PI ./PI_MC 100000000000000
the execute
- sbatch submit.sbatch
check if its running with
- squeue
to kill a batch job
- scancel JOBID
On minerve
Sample script to submit 10 batch jobs.
the filename is minervesubmit and you run like
source minervesubmit
cd /home/foretony/src/GEANT4/geant4.9.5/Simulations/N02wROOT/batch qsub submit10mil qsub submit20mil qsub submit30mil qsub submit40mil qsub submit50mil qsub submit60mil qsub submit70mil qsub submit80mil qsub submit90mil qsub submit100mil
The file submit10mil looks like this
#!/bin/sh #PBS -l nodes=1 #PBS -A FIAC #PBS -M foretony@isu.edu #PBS -m abe # source /home/foretony/src/GEANT4/geant4.9.5/geant4.9.6-install/bin/geant4.sh cd /home/foretony/src/GEANT4/geant4.9.5/Simulations/N02wROOT/batch/10mil ../../exampleN02 run1.mac > /dev/null
use
qstat
to check that the process is still running
use
qdel jobID#
if you want to kill the batch job, the jobID number shows up when you do stat.
for example
[foretony@minerve HW10]$ qstat Job id Name User Time Use S Queue ------------------------- ---------------- --------------- -------- - ----- 27033.minerve submit foretony 00:41:55 R default [foretony@minerve HW10]$ qdel 27033 [foretony@minerve HW10]$ qstat
