The
job queues on all SGI/Cray computers operated by SCD
have changed to be consistent with each other. (This is called
the Unified Queue Structure.)
The primary purpose of the Unified Queue Structure is to establish
a consistent batch environment for all systems serving as
computational engines within the NCAR environment. In addition,
the Unified Queue Structure provides a flexible, priority-based
job queuing and scheduling structure that can be rapidly adapted
to the evolving needs of the NCAR user community.
A common set of queues has been established to which users submit
jobs, regardless of the machine on which the job is to be run. This
set of queues is priority based -- that is, system resources are scheduled
based on queue priority.
There are four basic queues:
- prem (premium)
- reg (regular)
- econ (economy)
- sb (standby)
The regular queue is meant to be the primary target of most work,
and should provide timely job turnaround. The other queues are then
available for users to selectively discriminate the priority or
urgency of their work. Additional special-purpose queues are also
available; these are used infrequently and have special restrictions.
