Abstract

The Load-Program-Parameter and CPU-Measurement Facilities (SA23-2260-06)

Content

The first part of this document defines the Load Program Parameter instruction in the z/Architecture architectural mode. The facility is a prerequisite for the CPU measurement sampling facility.

The second part of this document defines the CPU Measurement Facility in the z/Architecture architectural mode. The facility consists of two parts: a CPU measurement counter facility and a CPU measurement sampling facility. The former provides a means to measure activities in the CPU and some shared peripheral processor; the latter provides a means to take a snapshot of the CPU at a specified sampling interval. The CPU measurement sampling facility requires the set program parameter facility as a prerequisite. Each part consists of a number of new instructions and several events of a new external interruption subclass. Measurement data provided by the CPU measurement facility is intended for software performance tuning.
