bullet MPI users
The bulletmpi queues are not associated with these fairshare policies. MPI parallel jobs reserve cores across multiple hosts. This does not work well with fairshares because the fairshare formula takes reserved cores into consideration. Large parallel jobs would never start because a job's dynamic scheduling priority would drop before it reserves all the cores it needs to get started. The bulletmpi queues have a higher queue-level priority than all of the fairshare general queues. For this reason we do not assign general queue fairshares for MPI investments.
AllUsers 'Tax'
The stakeholders subside the AllUsers ("free") fairshare by paying a 15% tax on their shares:
