We focus on the execution time of network simulator ns-2. This paper also evaluates and compares the performance of a PC cluster, which is commercially available. Through simulation experiments, this paper shows the cluster using conventional PCs can achieve the performance comparable to the PC cluster of the commercial version. However the improvement becomes saturated due to the overhead of the job scheduling, if the execution time of a simulation is relatively small. In the environment where simulations produce large files stored in a shared disc, the execution time become large due to the bottleneck of the shared disc and the network bandwidth. Tuning of the simulation system, for example using local discs, is needed.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福井工業大学"}]},"item_10002_relation_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"TF00009477","subitem_relation_type_select":"NCID"}}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鹿間, 敏弘"}],"nameIdentifiers":[{"nameIdentifier":"17554","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shikama, Toshihiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"17555","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-05-15"}],"displaytype":"detail","filename":"kiyou4007.pdf","filesize":[{"value":"6.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kiyou4007.pdf","url":"https://fut.repo.nii.ac.jp/record/2430/files/kiyou4007.pdf"},"version_id":"f8b2668f-ab9f-455a-8361-2f28246fcf64"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"PC cluster","subitem_subject_scheme":"Other"},{"subitem_subject":"PBS","subitem_subject_scheme":"Other"},{"subitem_subject":"network simulations","subitem_subject_scheme":"Other"},{"subitem_subject":"multi-core","subitem_subject_scheme":"Other"},{"subitem_subject":"Torque","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"複数PCによるネットワークシミュレーションシステムとその性能評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"複数PCによるネットワークシミュレーションシステムとその性能評価"},{"subitem_title":"A Network Simulation System with Multiple PCs and Its Performance Evaluation","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"2","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-07-24"},"publish_date":"2010-07-24","publish_status":"0","recid":"2430","relation_version_is_last":true,"title":["複数PCによるネットワークシミュレーションシステムとその性能評価"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-20T13:56:45.896723+00:00"}
