Abstract
A facility is provided for collecting time-slice-instrumentation information during processing unit execution. The facility counts, at least in part, occurrence of a specified processing unit event during a time-slice of processing unit execution. The counted events occurring during a first interval of execution and a second interval of execution of the time-slice are retained. The first interval of execution is earlier in the time-slice than the second interval of execution, and the counted events facilitate adjusting performance of the processing unit. In an embodiment, the time-slice is a contiguous period of time of processing unit execution, and the specified processing unit event includes a cache event. The processing unit may interleave processing of multiple different units of work across multiple contiguous time-slices, and during a single time-slice, a single unit of work of the multiple different units of work is processed by the processing unit.
