摘　　要：In this paper,the method of roofline model-guided compilation optimization parameter selection(RMOPS)is proposed based on Roofline model to maximize the performance of targets.Through the orthogonal test design compiler,the problem of optimization parameter selection in complex dependencies was solved.The performance data generated by empirical roofline tool(ERT)were used to implement the optimization parameter selection decision.RMOPS method was evaluated on ARMv8 platform,and the feasibility of RMOPS method was verified by using SPEC CPU2017 and NPB.Experimental results show that the program performance obtained by using the optimal optimization parameters of RMOPS search is generally improved by 5%–33%compared with that achieved by-O3 optimization parameter setting.
