- Install: redirect XDG_CACHE_HOME, UV_CACHE_DIR, MPLCONFIGDIR to
$VSC_SCRATCH before any pip/module activity ($VSC_HOME is only ~3 GB)
- train.pbs:
- Set same cache env vars at job start
- Write run outputs and WandB cache to $VSC_SCRATCH during the run (fast I/O)
- Copy results to $VSC_DATA/runs/<jobid>/ on completion for persistence
- Redirect PBS stdout/stderr to $VSC_DATA/runs/<jobid>/job.{out,err}
- Add cd $PBS_O_WORKDIR as first step (HPC best practice)
- env/hpc/modules.txt: curated list of HPC EasyBuild modules loaded by vsc-venv
- env/hpc/requirements.txt: pip packages not covered by HPC modules (auto-generated)
- scripts/export_hpc_requirements.py: developer utility to regenerate requirements.txt
from pyproject.toml; to be called by CI when pyproject.toml changes
