MegaScript regards independent sequential/parallel programs as tasks and executes them in parallel. The current implementation is based on a centralized control architecture which consists of a master host and slave hosts. The former controls and manages the latter, and the latter execute tasks. However, the architecture lacks scalability because the master host will be the bottleneck for the large number of slave hosts. Although we have proposed and developing a new implementation based on a hierarchical model, which reduces the load of the master host, its communication is still inefficient. Therefore, we propose an efficient communication scheme for the hierarchical model.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","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":"2012-07-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2012-HPC-135"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
