Econometrics Laboratory Accounts

Account Disk Space

The allocation of disk space on all accounts is controlled by disk quotas.

Below are the default allocations for home directories:
  Graduate students: 5 GB
  Faculty: 5 GB
  Staff: 1 GB
  Visiting Faculty: 1 GB
  Guest Accounts: 1 GB

To check quota limits, please run the command "quota" on a terminal.

If more disk space is required, users can request additional space by providing written justification to the EML manager. It is expected that requests for increased disk allocation come after basic account maintenance: deletion of files in trash, removal of obsolete data, archiving or compressing of no longer used files, and so forth.

All users have access to additional disk areas on the EML system. These include:

/tmp or /var/tmp is local to every workstation, i.e., to emily1,...,emily10, and compute servers we support. /tmp is volatile, and is never backed up. Depending on the machine, this space could be quite large. Files can be erased at any time if the workstation is rebooted. Files may be automatically deleted after 24 hours. This is truly "temporary" storage. Users should remove their files as soon as their work has been completed.

Public directories in the scratch partition (/scratch/public) is a central common area on the main server. Anyone can write files to this area. Users can make a subdirectory under your login name, and store files there. By default, this area is not private, so don't put anything in public scratch that is sensitive in nature. Files are not backed up, but they do not disappear when the server is rebooted. Files are removed by age (oldest first) and by size, as the area fills up.

Users are recommended to store critical files and confidential files safely in personal accounts, and use the unix file permissions to make these files secure and private (see 'man chmod'). Delete any old files that are no longer needed or that can be easily re-created. Compress large files. The command 'bigfiles' will show you your biggest files when invoked in your current working directory.

Printing

  • Printing: Student and faculty accounts are charged $0.05/page for any printing above their quota established according to the following categories:

    	300 class account, per semester
    	600 dissertation, per semester
    

  • Contractor and non-economics UC staff accounts are charged for all printing at the rate of $0.05/page. Research projects are charges for all printing at the rate of $0.10/page.

Accounts must be renewed according to the following schedule:

  • Class accounts expire at the end of each semester and cannot be renewed.
  • Graduate accounts for Economics students are valid as long as the individual is currently enrolled (registered)
  • Alumni accounts are issued upon request to individuals who have left the Department in good standing and are valid for up to two months after separation from the Department if reasonable cause can be demonstrated. Alumni accounts cannot be renewed.
  • All other student accounts expire on January 1 and July 1 of each year and must be renewed.
  • Guest accounts must be renewed each year by July 1 and require approval of the sponsoring faculty member.
  • Faculty and visitor (associate research fellows) accounts expire upon termination of their appointments.
  • Contractor accounts are valid indefinitely, as long as the account is in good standing.
  • All other accounts expire on July 1 of each year and must be renewed.

Requests for extension of an account must be received within 5 days of the account expiration date (send electronic mail to rowilma @econ.berkeley.edu).
