Users - managing your account¶
User responsibilities¶
When you are granted access to the Hoffman2 Cluster, you accept:
Each person is allowed only one Hoffman2 Cluster user account. If you require access to multiple research groups, please submit a request to add/join a secondary group via our online helpdesk.
Hoffman2 Cluster user accounts are single user IDs and are not to be shared. If sharing is detected, your account will be disabled.
All accounts on the Hoffman2 Cluster are governed by a set of Security Policies, which include UCLA Policy 401: Minimum Security Standards for Network Devices and UCLA Policy 404: Protection of Electronically Stored Personal Information. Please read and familiarize yourself with these UCLA and Hoffman2 Cluster policies.
Personal information and other sensitive data, including statutory, regulatory, and contractually protected data - for example, human subjects research, restricted research, student and educational data, and personal health information (PHI) - are prohibited on the Hoffman2 Cluster.
You are expected to keep your contact information current for cluster-wide communication. To do so, please login into your My Profile page of the System Identity Manager at: https://sim.idre.ucla.edu/sim/profile and update your Hoffman2 Cluster identity profile.
If you have any questions, please open a new support ticket via our helpdesk
Account expiration¶
Hoffman2 Cluster user accounts must be renewed annually by your sponsor, typically on the anniversary of the account’s creation date. Expired user accounts that are not renewed will be scheduled for deletion from the system, including any permanent data in their home and scratch directories. For more information, please see below Data retention.

Data retention¶
Data in your home directory never expires as long as your user account is active. If your access to the Hoffman2 Cluster is revoked by your sponsor or if your account expires, your account will be disabled and you will be given a grace period to find a new sponsor. After the grace period, your account will be removed from the system and any data on your home and scratch directories will be removed from the system. Please see the page, Storage for more details on the available cluster file systems.
If your sponsor has purchased additional project storage, any data on your sponsor’s purchased project directory will be transferred to your sponsor or their appointed delegate.
