How the Allocation System Works

Job Submission

In job submission stage, Slurm will ensure the project account has enought credit to run a job to the end. It will calculate the CPU-Hours requested by such job (CPU Hours=Walltime x Num_CPU_Cores). There are two situations that a job will be rejected by Slurm due to credit-related issue:

  • If project's available credits is insufficient for running the job.
  • Project has enough available credit, however some running jobs (of the same project) are consuming credits and will sooner or later used out all project credits.

If job rejectection happens and an error message shows up, please see Diagnosing Problems with Jobs for more details.

Job Runnning

When a job is running, Slurm does real-time credit charge at a certain time interval. You will find the project credit be deducted continuously until job complete.
