It is required to make clear electronic states of the conductive polymers in order to design materials which have electrically stable conductivities. The electronic states are represented by the time-dependent Schrodinger equation and a linear system of equations is derived from its discretization. In this paper, we considered the two-dimensional Poisson's equation as a model problem. We applied two sparse matrix storage formats, or CCS format and a new skyline-type format, to hold the coefficient matrix of a linear system of equations which is obtained by discretization of the Poisson's equation with one-way dissection ordering, where the coefficient matrix is sparse, symmetric, and positive definite. The performance of the formats was evaluated and the new formant was found to be efficeint.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"10","bibliographic_titles":[{"bibliographic_title":"研究報告ハイパフォーマンスコンピューティング(HPC)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2017-12-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"19","bibliographicVolumeNumber":"2017-HPC-162"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":184899,"updated":"2025-01-20T03:08:51.247577+00:00","links":{},"created":"2025-01-19T00:52:10.613648+00:00"}
