Job restrictions

Job restrictions

There exist several restrictions to the submission of jobs.

  • Jobs are guided to the correct partition depending on the requested resources, so you don't need to set a partition and if you chose the wrong, this will be corrected. Exemption to this is the partition c16s.
  • If the user/project is slightly over quota, the jobs will be sent to the corresponding low partition, where jobs only start, if they do not prolong waitingtimes of jobs in the unrestricted partition.
  • for the project "default" (please don't request that account, it will be set, if no account is given)
    • students/trainees have a monthly quota of 500 corehours
    • all other users have a monthly quota of 2000 corehours
    • if you used more than 3 times that value in the last 4 weeks, you will get a hint regarding compute projects during submission
    • if you used more than 15k corehours in the last 4 weeks, you will get a warning, that submission will be disabled soon
    • if you used more than 36k corehours in the last year, you will get a warning, that submission will be disabled soon
    • if you used more than 20k corehours in the last 4 weeks, further submission will be disabled until the used corehours in the last 4 weeks get below that limit
    • if you used more than 48k corehours in the last year, further submission will be disabled until the used corehours in the last year get below that limit
  • for any other quoted project, the following limits apply:
    • the monthly and total quota for a project can be looked up via "r_wlm_usage -q"
    • if the project used more than 1 times its total quota, you will get a warning, that submission will be disabled soon
    • if the project used more than 4 times the monthly quota within the last 4 weeks, you will get a warning, that submission will be disabled soon
    • if the project used more than 2 times its total quota, further submission will be disabled
    • if the project used more than 6 times the monthly quota within the last 4 weeks, further submission will be disabled until the used corehours in the last 4 weeks get below that limit
