This code corresponds to an implementation of the tapered All-Silicon Tracker design described here into the Fun4All framework.

1. The code was originally ran inside a Singularity container, which can be found here: https://github.com/sPHENIX-Collaboration/Singularity One needs to run ./updatebuild.sh and follow the steps in the README of that repo.

2. The code needs to built and installed with Fun4All, as outlined here: https://wiki.bnl.gov/sPHENIX/index.php/Example_of_using_DST_nodes. References to for this repository mean g4lblvtx/src/, where one should see the autogen.sh file. Create a build and install directory (I suggest in the same directory that holds this repo) and follow the instructions under the "Building a package" section from the link.

The main steps are:

mkdir build
cd build
/global/path/to/g4lblvtx/source/autogen.sh --prefix=$MYINSTALL
make -j 4
make install
source /global/path/to/Singularity/cvmfs/sphenix.sdcc.bnl.gov/x8664_sl7/opt/sphenix/core/bin/sphenix_setup.sh -n
export MYINSTALL=/global/path/to/Singularity/install
source /global/path/to/Singularity/cvmfs/sphenix.sdcc.bnl.gov/x8664_sl7/opt/sphenix/core/bin/setup_local.sh $MYINSTALL

From outside the container:

1. cd cori_batch.
2. Edit the run_shared.sh script (see instructions below).
3. Run sbatch run_shared.sh

Edit the following lines:

1. #SBATCH --time=1:00:00 -> Approximate time that running a job will take. A higher value ensures that your job is not stopped because it is taking too long. A lower value ensures that your job starts running sooner.
2. #SBATCH --array=0-999 -> This means the output will be split into 1000 output root files.
3. shifter ./AllSi_shifter.sh $SLURM_ARRAY_TASK_ID 100 -> The important parameter to keep in mind here is the number at the end of the line. This is the number of events per root split.
