As processor design has been transiting from homogeneous multicore processor to heterogeneous multicore processor, traditional Amdahl's law cannot meet the new challenges for asymmetric multicore system. In order to further investigate the impact factors related to the Overhead of Data Preparation (ODP) for Asymmetric multicore systems, we evaluate an asymmetric multicore system built with CPU-GPU by measuring the overheads of memory transfer, computing kernel, cache missing and synchronization. This paper demonstrates that decreasing the overhead of data preparation is a promising approach to improve the whole performance of heterogeneous system.

This study aims to elucidate the content and format of school safety standards to clarify the roles and responsibilities of schools in realizing school safety. Toward this end, difficulties in operating school safety standards at various sites were classified into four small groups with a total of 26 educational administrators, superintendents, and researchers to listen to the opinions of experts in the field and analyze related data. As a result, we comprehensively analyzed in-depth interviews with the respondents who are working at provincial offices of education regarding the proposed school safety standards. We also analyzed the necessity of developing these standards and examining the appropriateness of their content and format. Results were derived from four aspects, including the field applicability of such standards. The study draws the following conclusions. First, it focuses on setting the direction for the development of school safety standards. Second, it highlights the exploration of the system and content of these standards. Third, it pertains to the preparation of a draft of these standards.
