View job affinity information

Each job on the iSeries™ contains memory and processor affinity information.

The affinity information describes whether threads will have affinity to the same group of processors and memory as the initial thread when they are started. It also specifies the degree to which the system tries to maintain the affinity between threads and the subset of system resources they are assigned to. In addition, the affinity information specifies whether a job is grouped with other jobs so they have affinity to the same subset of system resources.

By grouping threads together that share a common set of data in main storage, your system's caching and memory access rates can improve.
