We constructed a prototype system of HMCS with a general purpose scientific parallel processor CP-PACS and a gravity calculation parallel processor GRAPE-6 connecting them via commodity-base parallel network. On the prototype of MCS, a micro-scopic gravity calculation on GRAPE-6 and a macro-scopic radiative-transfer hydrodynamics calculation on CP-PACS are performed simultaneously to realize detailed simulation on computational astrophysics. Both systems are connected via parallel network controlling system named PIO (Parallel I/O System). On each time step, all data of particles are exchanged between two systems hiding communication latency with a special algorithmand buffering effect by PIO. In this paper, we describe the overall concept of HMCS, its application and system implementation, and the performance evaluation of a prototype system.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"229","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌ハイパフォーマンスコンピューティングシステム（HPS） "}],"bibliographicPageStart":"219","bibliographicIssueDates":{"bibliographicIssueDate":"2002-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG06(HPS5)","bibliographicVolumeNumber":"43"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":17841}
