Where should I store my files?

WARNING!
Never store anything on a /scratch filesystem or in /tmp that you cannot afford to lose!
NO /scratch filesystem is ever backed up!

  • Source code and executables
    • /home
    • /tigress (but don’t make it your job's current working directory,
              and don't write your output here while the job is running)
  • Static data
    • /home
    • /tigress
    • /scratch/gpfs (short term)
  • Job output and intermediate results
    • /tmp (fastest since each compute node has its own) See example
    • /scratch/gpfs (fast parallel file system)
  • Final results for the long term
    • /tigress

Writing data to /scratch/gpfs is about 10 times faster than writing to /home.
