The resources are allocated to the job in a fair-share fashion, subject to constraints set by the queue and resources available to the Project. The fair-share at Anselm ensures that individual users may consume approximately equal amount of resources per week. Detailed information in the [Job scheduling](job-priority/) section. The resources are accessible via several queues for queueing the jobs. The queues provide prioritized and exclusive access to the computational resources. Following table provides the queue partitioning overview:

## Resources Accounting Policy
### Core-Hours
### Wall-clock Core-Hours (WCH)
The resources that are currently subject to accounting are the core-hours. The core-hours are accounted on the wall clock basis. The accounting runs whenever the computational cores are allocated or blocked via the PBS Pro workload manager (the qsub command), regardless of whether the cores are actually used for any calculation. 1 core-hour is defined as 1 processor core allocated for 1 hour of wall clock time. Allocating a full node (24 cores) for 1 hour accounts to 24 core-hours. See example in the [Job submission and execution](job-submission-and-execution/) section.
The wall-clock core-hours (WCH) are the basic metric of computer utilization time.
1 wall-clock core-hour is defined as 1 processor core allocated for 1 hour of wall clock time. Allocating a full node (24 cores)
for 1 hour amounts to 24 wall-clock core-hours.
### Standardized Core-Hours (SCH)
The resources that are currently subject to accounting are the standardized core-hours (SCH).
The standardized core-hours are obtained from WCH by applying a standardization factor.
SCH = F*WCH
The accounting runs whenever the computational cores are allocated or blocked via the PBS Pro workload manager (the qsub command), regardless of whether
the cores are actually used for any calculation. See example in the [Job submission and execution](job-submission-and-execution/) section.
