Load/Store Characteristics for a Set of POWER Systems Benchmarks

We analyze the fraction of loads and stores in a set of POWER Systems benchmarks. The benchmarks include all of the SPECint2006 codes plus a set of commercial codes and a set of Python codes. The analysis is based on instruction traces collected from the execution of each of those benchmarks. We observe that on average the load/store instructions represent 40% of the total number of instructions. We also observe that loads and stores appear at a ratio of approximately 2-to-1.
