講演要旨:

Communication hiding is a well-known approach for realizing the higher performance of applications. Especially, to get ideal parallel performance with strong scaling, effective communication hiding essential. However, in some applications, we can not hide communications as we expect. In this study, we modelize communication hiding for each application and system. By this model, we judge the communication hiding is useful or not. In this talk, we discuss the validity of the model with general stencil problems.
