Info
titleDisk space
  • Your home directory is in weka (/sdf/home/<first letter of your userid>/<your userid>) with 30 GB of space. This space is backed up and is where code, etc., should go. 
  • We have group space at /sdf/group/fermi/:
    • some directories are under /sdf/data/fermi/, but we provide links into the group directory tree for easier access
    • includes shared software, including conda envs for Fermitools and containers for running rhel6 executables
    • Fermi-supplied user (i.e., on top of your home directory) space.
      • You can find it in /sdf/group/fermi/u/<you>. There is a symlink to it, called "fermi-user", in your home directory for convenience.
      • after gpfs is retired in late 2023, this is where your larger user space will be.
    • group space in /sdf/group/fermi/g/ - a one-time copy has been done of all the gpfs g/ directories, under /nfs/farm/g/glast/g/.
    • all of glast afs has been copied to /sdf/group/fermi/a/
    • the nfs u<xx> partitions were copied to /sdf/group/fermi/n/ (including u52 which contains the GlastRelease rhel6 builds)
  • your user/group space on the old clusters is not directly accessible from s3df - it currently needs to be copied over. (this access policy may get reversed soon)
    • We're still providing additional user space from the old cluster, available on request via the slac-helplist mailing list. It is not backed up. This space is natively gpfs.  User directories are available under: /gpfs/slac/fermi/fs2/u/<your_dir>.
    • During the transition, read-only mounts of afs and gpfs are available on the interactive nodes (not batch!).
      • afs is just the normal afs path, eg to your home directory (/afs/slac/u/ ...) - you may need to issue "aklog" to get an afs token.
      • gpfs is /fs/gpfs/slac/fermi/fs2/u/ ...
