We also show that we can describe a behavior corresponding to backtracking. Our scheme accepts a lower-level description than the original LTC. A task can be created not only to process a continuation but also to process a specified part for parallel execution. The low-level description can be used for the distributed computing such as cluster computing. Since the low-level description is sometimes undesirable, we also discuss its high-level description. We also enhanced GCC to reduce allocation overhead and maintenance overhead of nested functions. The results of preliminary performance measurements on various shared-memory parallel computers exhibit near-ideal speedups and quite low parallelization overhead.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"377","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"368","bibliographicIssueDates":{"bibliographicIssueDate":"2004-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG11(ACS7)","bibliographicVolumeNumber":"45"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T22:45:36.684012+00:00","links":{}}
