Recently, there are many types of supercomputing systems being equipped with vector processors, scalar processors, and accelerators as processing elements of the systems. Although all kinds of calculations cannot effectively be performed on one HPC system, a part of calculations can exploit the potential of a HPC system by considering both the calculations and the system. These tendencies that each HPC system is designed and suitable for specific fields of calculations continue in order to achieve higher performance for target HPC codes. Therefore, even though the same HPC code is executed on multiple HPC systems, the sustained performances on HPC systems are different. As characteristics of a HPC code mainly depend on optimization methods, clarifying the performances by the optimization methods on multiple HPC systems becomes important for developing performance-portable HPC codes, which can exploit the potential of every HPC system. By considering both the optimization methods and the HPC systems, this paper clarifies the performances of the optimization methods on multiple HPC systems.
