Often, users collaborating on a project wish to share their files with others in a common set of directories. Unfortunately, many decide to use a single login username as a group user. For security reasons, the sharing of accounts is explicitly forbidden by LONI and HPC@LSU policy, and such practices may result in the suspension of access for all involved.

It is possible to setup group permissions on a directory for groups that need to share data amongst themselves. This requires LONI System Administration to create a group and change the permissions on a directory to enable read/write access for that group.

How do I Create a Collaborative Directory

If you feel that a shared directory will help your group accomplish its research goals, begin by sending an email to (

When you contact us, be sure to provide the following information:

  1. your full name and username.
  2. the full names and usernames of all users you wish to have working in the collaborative directory.
  3. a brief description of what you are trying to do and what you hope to accomplish by requesting this change.
  4. the cluster that you are working on.
  5. the name of the directory that you would like to share (e.g., /work/username/share).
  6. the name by which you wish this group of users to be known.

Please note: requesting a shared directory on one of the clusters is not the same as requesting a /project storage allocation. Requests for additional storage space are handled by requesting a storage allocation on the LONI allocations web site.
