Resources in the job definition

This topic provides an overview of how resources and their properties are used in the job definition to identify possible targets, to reserve allocations of consumable resources, and to optimize load balancing between available resources.

An understanding of physical and logical resources and their properties is the key to creating a job definition that accurately targets suitable resources for running the job, determines the resource allocation requirement, and contributes to balancing the load between available resources. Each resource has one or more properties associated with it. Properties can have the following characteristics:

Is consumable: Properties of resources that are consumable have finite amount associated with them which can be consumed by the jobs that are allocated to the resource. For example, a computer system has a finite number of processors.
Can be optimized: Some properties can be used to define optimization objectives, which determine how load is to be balanced when jobs are allocated to a group of resources. For example, you could choose to allocate a job to the matching resource that has the lowest CPU usage.
Supports wildcards: Some properties can be specified in the job definition using wildcards. For example, a requirement for a particular series of computer models could be defined by specifying the model using wildcards.

Table 1 shows the different resource types that can be included in a job definition and their available properties.
