Project Directories

Any principal investigator (PI) may request a project directory to be shared by the research team. This project directory may be used to store data such as source code, binaries, and scripts. Project directories are accessible from all resources in


By default, project directories are created with your group as owner therefore members of your group have read and write permissions. Team members must be a member of that group to access the project directory.

To find out which group owns a project directory (assume your group's name is tugxyz):

>ls -ld   /nics/a/proj/yourGroupDirectory

drwxrwx--- 2 48 tugxyz 4096 2011-03-05 12:42 yourGroupProjectDirectory/

To check your current groups, and which one is the effective group (the first in the list) use groups:


tugxxx NICSxxx tabxyx tugxyz

To switch to the desired effective group (it will appear first in your list) use newgrp:

>newgrp tugxyz


tugxyz tugxxx NICSxxx tabxyx

Warning: Each time you switch to a new effective group it will create a child shell.


The default quota for a project directory is 100 GB. Project directories are periodically backed up to tape, however, it is recommended that critical information be backed up. By default, project directories are removed after the associated projects expire.

Project directories and home directories are on NFS servers, which are not designed for intensive I/O. For performance-critical purposes, please use the Lustre file systems available on Beacon.
