Common Location to Maintain Codes
BC Project: FY10-07
Date of Policy: 30 Sep 2011
Last Updated: 18 Apr 2019 (see Revision Log)
The main objective of this policy is to provide a common location to place applications and codes that are shared by multiple users without making use of home directories or scrubbed scratch space.
This policy requires each center to provide a common directory, accessible on
all login and compute nodes, for the installation of user-supported applications
and codes. The directory will be accessible from all login and compute nodes
via the pre-defined
$PROJECTS_HOME environment variable.
All individual projects may request a directory under
The top-level directory ownership will be set to the username of the point of
contact (POC) for the project directory. This user will have full access rights
and will not be required to use any specialized account to make changes. The
default group for the directory will be set to the POC's default group. A POC may
choose to allow access permissions to a different group, in which case the POC must
either specify the existing group to use or request to create a new one. It is the
responsibility of the account owner to maintain proper access controls for any
restricted data that resides in their project directory.
To request a new "project directory" the following information should be communicated to the HPC Help Desk:
- Desired DSRC system where a project directory is being requested.
- POC Information: Name of the sponsor of the project directory, username and contact information.
- Short Description of Project: Short summary of the project, which describes the need for a project directory.
- Desired Directory Name: This will be the name of the directory created under
Project directories will be handled according to the user data retention policies of the center if the project directory POC ceases being an account holder on the system.
Backup and Quota
Project directories will be backed up by the centers on the same schedule as home directories specified in BC policy FY12-01 (Minimum Home Directory Size and Backup Schedule). Users are still responsible to safeguard their own data.
Some centers impose quotas in the use of
$PROJECTS_HOME. Therefore, when requesting a
new project directory, users are strongly advised to include in their request an estimated size in
Gigabytes to ensure their request can be accommodated.
