Ramses Production Run

1. Freeze production state

• Lock source revision, compile flags, and namelist files.
• Build and archive one production executable.
• Store environment/module versions for full reproducibility.

2. Stage run directories

mkdir -p /scratch/<project>/ramses-prod/{ic,output,logs,restart}
cp <ic-and-namelist-files> /scratch/<project>/ramses-prod/ic/

3. Scheduler launch template

#!/bin/bash
#SBATCH -J ramses_prod
#SBATCH -N 8
#SBATCH --ntasks-per-node=64
#SBATCH -t 24:00:00
#SBATCH -o logs/slurm-%j.out

cd /scratch/<project>/ramses-prod
srun <path-to-ramses-binary> <input-namelist>

4. Run operations

• Monitor AMR growth, memory pressure, and I/O performance.
• Validate the checkpoint/restart chain before long run sequences.
• Run periodic science sanity checks during active jobs.
