Abstract
Provided is a method for estimating statistics of properties of interactions among instructions processed in a pipeline of a computer system, the pipeline having a plurality of processing stages. Instructions are fetched into a first stage of the pipeline. A set of instructions are randomly selected from the fetched instructions, a subset of the set of selected instructions concurrently executing with each other. A distances between the set of selected instructions is specified, and state information of the computer system is recorded while the set of selected instructions is being processed by the pipeline. The recorded state information is communicated to software where it is statistically analyzed for a plurality of sets of selected instructions to estimate statistics of the interactions among sets of selected instructions.
