File Systems

The Network File Service (NFS) server contains user's home directories, project directories, and software directories.

Home Directories

Each user is provided a home directory to store frequently used items such as source code, binaries, and scripts. See Home Directories for more information about their use and policies.

Project Directories

A principal investigator (PI) may request a project directory to store shared files and data. For more information, please refer to Project Directories.

Scratch Directories

Scratch space for staging temporary data and performing I/O with the compute nodes is available on the Lustre file system. This is the only file system available to the compute nodes. For information about the purge policy, and other specifics, please see Scratch Directories.

High Performance Storage System

The High Performance Storage System (HPSS) is an archival storage system jointly operated by NICS and NCCS. Data transfer between this system and the rest of NICS is provided by HSI. Please see HPSS.

TeraGrid Environment Variables

Environment variables have been set up for the TeraGrid to help make scripts work no matter which cluster they are run on. They provide a common user environment. You may choose to use these variables instead of hardcoding paths.
