Building Instructions | Benchmark Galaxies Collision

Environment software need in the system: MPI (e.g., MPICH, OpenMPI, IntelMPI), FFTW3, GSL, HDF5

1. Load the environment modules necessary to compile and run the code, e.g,

module load \
mpi/OpenMPI/4.0.3-GCC-9.3.0\
data/HDF5/1.10.6-gompi-2020a \
numlib/FFTW/3.3.8-gompi-2020a \
numlib/GSL/2.6-GCC-9.3.0 

2. In Makefile.systype select the machine you are using

3. In folder buildsystem make sure you have the Makefile.comp.xxx and Makefile.path.xxx (xxx = cluster name)
set with the proper paths and compilation options, respectively.

4. Compile the code

make CONFIG=Config_CollGal.sh EXEC=gadget4-collgal

5. mkdir gallcol_run

6. cp gadget4-collgal gallcol_run

7. You need the extra files to run the code: param.txt and TREECOOL (they are in the folder gadget4/examples/CollidingGalaxiesSFR)

Make sure that in param.txt you set the path to the initial conditions file.

8. set your SLURM configuration file to your needs and launch the run.
