FlexoMPI

The modules necessary to compile and run HORSES3D are:

module load gcc/11.2.0 hdf5/gcc11.2/1.14.2 openmpi/gcc11.2/4.1.6 metis/gcc11.2/5.1.0

Then, to compile:

make COMM=PARALLEL WITH_METIS=YES WITH_HDF5=YES

An example slurm script is included below:

#!/bin/bash
#SBATCH --job-name=iLES
#SBATCH --nodelist=n004,n005,n006,n007
#SBATCH --ntasks=192
#SBATCH --time=24:00:00
#SBATCH -e RESULTS/err%j.log
#SBATCH -o RESULTS/out%j.log
 
export OMP_SCHEDULE="guided"
export OMP_NUM_THREADS=1
 
module purge
