Resource Allocation and Job Execution
=====================================
To run a [job](../introduction/), [computational resources](../introduction/) for this particular job must be allocated. This is done via the PBS Pro job workload manager software, which efficiently distributes workloads across the supercomputer. Extensive informations about PBS Pro can be found in the [official documentation here](../../pbspro-documentation/sitemap/), especially in the PBS Pro User's Guide.

The resources are allocated to the job in a fairshare fashion, subject to constraints set by the queue and resources available to the Project. The Fairshare 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:
