this paper, we discuss a parallelization method for plasma electromagnetic particle simulation codes. Plasma particle codes are composed of particle subroutines, electromagnetic field subroutines, and fluid subroutines. The present method is based on combination between data division method for particles and area division method for fields and fluid. The parallelization number is independently set in each subroutine so that the code achieves best computing performance. With estimation of MPI communication and caluculation duration time, we establish a formula to evaluate the speed-up. We applied this method to a plasma particle code: a hybrid code. High parallelization performance, the speed-up is as high as 13.59 as a predicted value and 14.45 as an evaluated value in 16 PE system, is achieved.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"131","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌数理モデル化と応用（TOM）"}],"bibliographicPageStart":"118","bibliographicIssueDates":{"bibliographicIssueDate":"2002-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG07(TOM6)","bibliographicVolumeNumber":"43"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
