The talk will discuss workload metrics based on instruction grouping. the focus is on the Java bytecode instruction set, but the principles are generally applicable across architectures, wherever a workload can be described by frequencies of a set of instructions or other basic operators. We discuss the motivation and justification for grouping frequencies of related instructions and propose an iterative grouping methodology. The effects of our approach are demonstrated using cluster analysis of SPEC JVM98 benchmarks.
