Most of these algorithms can be classified into atom decomposition which aims at load balancing and space decomposition which aims at the minimization of communication cost. This paper proposes several new hybrid algorithms which consider the both.

Among these hybrid algorithms, small-cell based force decomposition algorithm shows the best performance; it achieves more than 10% speedup compared with the conventional space decomposition algorithm.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"66","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"61","bibliographicIssueDates":{"bibliographicIssueDate":"1999-03-04","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"21(1998-OS-080)","bibliographicVolumeNumber":"1999"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:56:39.398933+00:00","updated":"2025-01-22T19:15:44.508482+00:00","id":25895}
