On the other hand, it is also well known that it requires huge amount of time to find good codes, especially in evaluating a code that has been calculated. We deployed GPGPU on our machine for reducing the calculation time. Our approach with GPGPU results in the fact that it runs more than 4(appx. 4.927) times faster than the one without GPGPU.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告数理モデル化と問題解決（MPS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-02-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2010-MPS-77"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":68005,"updated":"2025-01-22T00:24:00.757487+00:00","links":{},"created":"2025-01-18T23:28:09.672162+00:00"}
