Maximum submission jobs per user
Each user can submit as many jobs as prefers because there is no limit for job submissions per user.
Maximum running jobs per user
When a user submits jobs to HTCondor, the scheduler, which the user is assigned, allocates the jobs in a queue in order to match these jobs to the proper execute machines regarding their requirements (job's requirements and machine's requirements). In each scheduler is set only 10.000 jobs to run simultaneously. For instance, even if a user submits 20.000 jobs, only a few thousands of them can run at the same time because of the max running jobs in the scheduler and also because of the fair-share.
The system will remove automatically the held jobs if they are in hold state for more than 24 hours.
Multiple running jobs
The system will remove automatically the jobs which restarted for more than 10 times.
