Abstract:

Compatible evaluation of desktop operating system (DOS) and processor is crucial to promote the quality of the computer system. Traditionally, the evaluation of DOS mainly focuses on software, while the compatible performance between processor and DOS is barely concerned. SPEC 2000 is proposed to evaluate the compatible performance of processor and DOS in this paper. Eliminatingfactor  (λ)  is adopted to evaluate the influence difference of benchmark suits on different DOSs. Three DOSs are used in the experiment, and the results show that the benchmark suit may change the running results of SPEC 2000 of two DOSs under certain eliminatingfactor  (λ) . The proposed eliminatingfactor can be used to improve the performance of DOS and help choosing a robust benchmark suit.
