| Research Abstract |
To establish a key component of"automatic tuning technology"on multi-core processors and multi-GPU's for a next-generation supercomputer system, we conducted this research project. In this work, we developed an"automatic tuning technique employing performance stabilization on GPU's"and an"automatic tuning technique which utilizes a performance database". Furthermore, we successfully gave the semioptimal experimental design based on a Bayesian model through the mathematical research of the automatic tuning when the environmental conditions change dynamically. AT(automatic-tuning) for eigenvalue solvers, Fast Fourier Transform, and iterative solver with preconditioning were exploited on a cluster system or a multicore computer system.
