VSC-4 provides three facilities for persisting data: the high-performance IBM Spectrum Scale Parallel Filesystem, BeeGFS Parallel Filesystem (former Fraunhofer Parallel Filesystem, FhGFS) and a node-local SSD. They are accessible under:

• IBM Spectrum Scale:
  • $HOME expands to /home/fs<project>/<username>,
  • $DATA expands to /gpfs/data/fs<project>/<username>
• BeeGFS (former FhGFS):
  • $BINFL expands to /binfl/lv<project>/<username>,
  • $BINFS expands to /binfs/lv<project>/<username>
• Local SSD
  • /local

Usage $HOME

$HOME is the location of the user UNIX home directory. It can be accessed from login and compute nodes. $HOME should be used for storing/compiling code - data for which high concurrent job throughput and support for large file sizes is not required. Quota on $HOME is 100GB and 10^6 number of files and can not be extended
