Storage and Scratch

Home Directory
Every user has a personal home directory at 
/home/your_username. This is your default working directory when you log in.
Backed up via Legato — see TAU backup info
For purchasing additional storage, see storage pricing
NetApp storage includes snapshots for file recovery
Scratch Partitions
Scratch partitions are shared, high-speed temporary storage available across the cluster:
/scratch100
/scratch200
/scratch300
Use scratch for intermediate files during a job run — not for long-term storage.
Local Scratch
Some compute nodes and workstations have a local 
/localscratch partition. This is node-local storage — faster than shared scratch but only accessible from that specific node.
If your job uses 
/localscratch, you must clean up after yourself. Add this to your job script:
export CACHEDIR=/localscratch/${USER}_${SLURM_JOB_ID}
mkdir -p $CACHEDIR
cleanup() {
  rm -rf -- "$CACHEDIR" || true
}
trap cleanup EXIT INT TERM HUP
Important
Scratch is not backed up — do not store anything you cannot afford to lose
Clean up scratch files after your job completes
Do not use scratch as a permanent storage location
