Managing your Account
Changing Contact Information
Contact information for each user is kept in the NERSC Information management (NIM) system. In order to communicate effectively with users and in order to abide by DOE computer use regulations we must have the following information for each user: name, citizenship, email address, work phone number, and work institution (organization).To see your Personal Contact Information page in NIM select My Contact Info from the My Stuff pull-down list in the NIM main menu. To update this information, select the Update link.
Changing Passwords
LDAP (which stands for Lightweight Directory Access Protocol) is being used to manage all NERSC machines which means all machines share a common password, which is the same as your NIM password. If you need to change a password on such a machine, change your NIM password and the new password will be propagated to the LDAP-managed machines within a few minutes. To change your NIM password, select Change NIM Password from the Actions pull-down list in the NIM main menu.
Changing Shells
Use NIM to change your default shell. To do this, select Change Shell from the Actions pull-down list in the NIM main menu.
Changing Default Repos
Allocations of NERSC computer time are awarded into project accounts, called repositories or repos. Each user has a default repository. All interactive charges are charged to the default repo. Batch jobs are also charged to the default repo if no repo (account) is specifically assigned to the job.Users can see their default repo in the NERSC Information Management (NIM) system on the Account Usage Summary page. This is the page that is displayed when you first login to NIM (or select My Account Usage from the NIM main menu). Look at the columns:
- Dflt Now?: a Y indicates the default repo currently in effect
- Base Repo? a Y indicates that this is the repo you have chosen (or were given) as your default repo. This will be your default repo unless your user balance is negative in that repo, in which case NIM will set another repo (if you have one) as your temporary default repo.
To change your base default repo, select Change Default Repo from the Actions pull-down list in the NIM main menu.
