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 NICS resources (except Kraken compute nodes) in
/nics/a/proj/
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:
>groups tugxxx NICSxxx tabxyx tugxyz
To switch to the desired effective group (it will appear first in your list) use newgrp:
>newgrp tugxyz >groups 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 10 GB. Project directories are periodically backed up to tape, however, NICS recommends that critical information be backed up to HPSS independently. 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 Kraken, and Nautilus.
