Here, we propose a new algorithm to improve the parallelization performance of message passing interface (MPI)‐communication in the MPI‐parallelized fast multipole method (FMM) combined with MD calculations under three‐dimensional periodic boundary conditions. Our approach enables a drastic reduction in the amount of communication data, including the atomic coordinates and multipole coefficients, both of which are required to calculate the electrostatic interaction by using the FMM. In communications of multipole coefficients, the reduction rate of communication data in the new algorithm relative to the amount of data in the conventional one increases as both the number of FMM levels and the number of MPI processes increase. The aforementioned rate increase could exceed 50% as the number of MPI processes becomes larger for very large systems. The proposed algorithm, named the minimum‐transferred data (MTD) method, should enable large‐scale and long‐time MD calculations to be calculated efficiently, under the condition of massive MPI‐parallelization on exascale supercomputers.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Wiley", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1002/jcc.26524", "subitem_relation_type_select": "DOI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "\"This is the peer reviewed version of the following article: [Andoh, Y, Ichikawa, S, Sakashita, T, Yoshii, N, Okazaki, S.
