An optimizing compiler that directly analyses shared-memory source programs is indispensable for improving theperformance of software DSM systems.The purpose of compiler optimization is to generate codes reducing thecommunication and instruction overheads for software cache-coherencemanagement.The optimizing compiler  performs interprocedural points-to analysis andinterprocedural shared-access set calculations by using intervalanalysis to solve redundancy elimination equations along with lazyrelease consistency model.It generates the codes that avoidfetch-on-write. We have implemented this optimizing compiler, Remote CommunicationOptimizer: RCOP.We also have implemented the lightweight runtimesystems on an SS20 workstation cluster connected with the FastEthernet (100BASE-TX).  The experimental results using the SPLASH-2benchmark suite show that the combination of the optimizing compilerand software DSM is very effective.Our proposed system had highspeed-up ratios for the FFT and Radix programs, that is, challengingapplications for software DSM (about 4 times faster than sequentialprograms on 16 processors).","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"897","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"879","bibliographicIssueDates":{"bibliographicIssueDate":"2001-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"42"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"並列化コンパイラ"}]},"weko_creator_id":"1"},"created":"2025-01-18T22:46:29.433279+00:00","updated":"2025-01-23T01:52:28.757955+00:00"}
