  • See EZFILES and Home Directories for details.

Temporary File Systems

  • Various temporary file systems (global and local) are for system use, temporary storage of I/O local to each machine, or large temporary storage for I/O shared among many machines.
  • See EZFILES and Temporary File Systems for details.

/usr/workspace File Systems

  • 2 TB of NFS mounted file space is provided for each user and group.
