Job Accounting

The webpage Accouting and NPL gives you more information about job accounting.

Every batch job on Lise and Emmy is accounted. The account (project) which is debited for a batch job can be specified using the sbatch parameter --account <account>. If a batch job does not state an account (project), a default is taken from the account database. It defaults to the personal project of the user, which has the same name as the user. Users may modify their default project by visiting the HLRN service portal.
