Name Notation Units Comment Memory footprint – Bytes Total space occupied by the program in memory Execution time (∑ CPIj) * clock cycle time, where 1 ≤ j ≤ n Seconds Running time of the program that executes ninstructions Arithmetic mean (E1+E2+…+Ep)/p Seconds Average of execution times of constituent pbenchmark programs Weighted Arithmetic mean (f1*E1+f2*E2+…+fp*Ep) Seconds Weighted average of execution times of constituent p benchmark programs Geometric mean pth root (E1*E2* …*Ep) Seconds pth root of the product of execution times of pprograms that constitute the benchmark Static instruction frequency % Occurrence of instruction i in compiled code Dynamic instruction frequency % Occurrence of instruction i in executed code Speedup (MA over MB) EB/EA Number Speedup of Machine A over B Speedup (improvement) EBefore/EAfter Number Speedup After improvement Improvement in Exec time (Eold-Enew)/Eold Number New Vs. old Amdahl’s law Timeafter = Timeunaffected + Timeaffected/x Seconds x is amount of improvement
