Abstract

Performance = 1/Time The goal for all software and hardware developers is to increase performance Metrics for measuring performance (pros/cons?) Elapsed time CPU time • Instruction count (RISC vx. CISC) • Clock cycles per instruction • Clock cycle time MIPS vs. MFLOPS Throughput (tasks/time) Other more subjective metrics? What kind of workload to be used? Applications, kernels and benchmarks (toy or synthetic)
